Ritchey–Chrétien enjoyers thread

[harsh matrix]

understandable

this is 2 hours of lum from my backyard with the full moon

@frosty shard I was talking to the friend of the guy i bought my RC from, this friend told me about the scope, and he said that he thinks the baffle extension might be too long

I think he is crazy, even still

but im looking at this data

and there are no dust motes...

aside from that

beautiful edge on spiral

im going to go hard on it this season

[frosty shard]

Oh sicc, from tonight?

[tight lodge]

Wait... You fixed the RCT?

[runic violet]

No I'm not

[vapid patio]

Thanks bro

Anything pixinsight I missed? I'm out of the loop for sure

Anything blurX?

[tight lodge]

V1.1 of MAS

[vapid patio]

Ok cool cool and has pixinsight come out with a new update?

[tight lodge]

Yes sir

[vapid patio]

Cool thanks man

[sinful sapphire]

i need all of you to cross your fingers for me because if everything goes right and I am really lucky

I could own a 10'' Truss Ritchey-Chretien by summer

[frosty shard]

JOIN US

[sinful sapphire]

pray for me

i found a really good used deal i can profit on

[frosty shard]

Satanic ritual incoming, currently tracing the pentagram

[vapid patio]

@harsh matrix What’s your backlash settings

We have around the same weight on our focuser

[high aspen]

meowogram

[harsh matrix]

what autofocuser do you have?

[vapid patio]

Zwo eaf

[harsh matrix]

[harsh matrix]

then I can't help you

you have to figure that part out on your own

[vapid patio]

Dang it

Well what’s yours so I get a idea

[stiff mason]

Gang should i get an 8 inch RC or a 10 inch rc i feel like 8 inch what do yall say

[runic violet]

Lol what mount

[stiff mason]

I will get a harmonic later on probably something like a ragdoll 20 pro or MlAstro sl33

Well i will get the harmonic first

[harsh matrix]

i think you could pick either of them with those mounts tbh

i know a dude running a 9.25" SCT on an Umi 20S

he gets insane numbers for a harmonic

stuff my am5n can't hope to achieve

[runic violet]

You have to trust those numbers

[vapid patio]

@harsh matrix How do you test to see how much backlash you need

[runic violet]

I.e. need oag, phd2 not asiair

[stiff mason]

It's because of the low pe which is at a reported 10 arcsecond

[harsh matrix]

run an autofocus run and see what the graph looks like

[vapid patio]

Ok cool thought so

[harsh matrix]

if it has to "ramp up" before there are significant changes in focus, then you have to count how many changes it made before that change in focus occured

[runic violet]

Why not noot

[harsh matrix]

then based on your step size, multiply that number by your step size for a baseline

might need some fine tuning to get it perfect

[vapid patio]

Got it thank you

[frosty shard]

Do you want a portable setup or a permanent one? I'd say that's the deciding factor

My 8" RC is pretty portable with a strain wave mount

I feel a 10" would start to get unwieldy

[stiff mason]

Well i will be taking it off and on so portable id say but idk how awkward carrying a 10 inch will be

[high aspen]

10 ;3

[frosty shard]

Eh actually perhaps a 10" would be fine - I'm coming at this from the perspective of not having a car and not having a yard to set my scope up in

[stiff mason]

Yeah the weight isn't my biggest concern it's the size of the telescope because 30lbs the size of a tungsten cube will be easy to carry but a 30lb carboard box not so much

[runic violet]

10" closed tubes have like 16" diameter tubes

They're giant

The truss is even more on steroids

Not sure why it's that important if one has a car though because you just take it from the car onto the mount

[stiff mason]

Yeah thats my problem really from the car to the mount from the house to the car altho the ladder isnt too difficult

[harsh matrix]

okay the full night before DBE

looks a bit weird but tbh, not as bad as i was expecting for full moon luminance with a shorter baffle tube

[frosty shard]

That's the full field (IMX533 + reducer) right?

[harsh matrix]

yeah minus the cropped artifacts from stacking

[runic violet]

Do you understand why a longer baffle tube is a problem

[harsh matrix]

yes and no

The reason I think having it shorter is a problem is because you could already see past the secondary mirror directly outside with the stock extension

so shortening it is counterintuitive, on the surface

[runic violet]

It can't be too short for obvious reasons

But it can't be too long because it starts intruding in the light path

[harsh matrix]

[runic violet]

Likewise it can start providing internal reflections when it does so

[harsh matrix]

yeah ofc

[harsh matrix]

it already is doing that with out an extension

[runic violet]

The ray traced optimum is what you want and nothing else

[harsh matrix]

but if the internal reflections are not so severe that they render the data useless, such as in this case, this could realistically work...

[runic violet]

There's always going to be internal reflections you have to dampen by flocking/painting

But intrusion into the path makes it an order of magnitude worse

[harsh matrix]

hmmmm

so I told you

I had to break the extension I made strategically to test this

which makes it stick 3 or 4 mils out too far

I am going to take measurements of it and redesign it in a way that works better

the result could get even better

also like I said, i painted the tubes too

so as far as that goes, cant do much more there, but I can repaint the primary mirror retaining ring which could possibly improve things further too, because I flocked it for a while, then removed it because it was coming off, now it's shiny again

maybe you can look for yourself, but none of this appears to be from dust sooooooooooooo

huge win?

this is almost 4 hours of data under the full moon

if there's a problem, it would show by now

[frosty shard]

Oh man that looks so much better

[harsh matrix]

right?

this is so weird to me

but it makes sense if you take the theory into account

we went from this to the result above in about 2 weeks

this had dust motes

and the above example does not

this was less data on a moonless night

[runic violet]

It's good that I saw that msg

[harsh matrix]

which one?

that I thought you were crazy?

I see there was a method to the madness now

oh wait im a dummy

yes it is good that you saw that one

[runic violet]

Something something give up on rc

[harsh matrix]

yes

[runic violet]

Sct joke somewhere in there

[harsh matrix]

that one

yes

my galaxy season is saved

[runic violet]

As if scts have no problems with scattered light ever

[frosty shard]

A true Ritchey–Chrétien enjoyer improvises, adapts, and overcomes

[harsh matrix]

so now I want to try to improve things further but adding baffles to the inside of the baffle tubes made things worse...

I have to be rather strategic about the next choices I make

[frosty shard]

Though I don't blame you for being frustrated with the baffling problems at all

[harsh matrix]

Nobody online mentions that they discovered this problem by having stock baffling that was TOO LONG

[runic violet]

I'm more of a gregorian enjoyer these days but same difference

[harsh matrix]

so on my end, it feels like im the only person in existence to stumble upon this

💀

[runic violet]

There are at least two cn threads

[harsh matrix]

now im interested

well uh

i wasnt expecting full moon lum to look so good

maybe i get some color when it goes away

[runic violet]

Wouldn't it make more sense to get color while the moons out lol

And lum when it's gone

[harsh matrix]

yes and no

i did notice, last night, that the disc of the galaxy is warped

i love seeing this sort of thing in such clear detail

[runic violet]

Go image the integral sign galaxy

[frosty shard]

This is what caused my friend to sell his C6 and get an Askar 120 APO

[harsh matrix]

i do not believe ive heard of that before

[harsh matrix]

[runic violet]

Cursed image quality

[desert locust]

what mount u gonna use

[frosty shard]

Imma be honest there's a certain quality these kinds of internal reflections provide to images that I actually like...but at the same time I want to, like, opt into that

I actually had a stupid idea for getting more impressive diffraction spikes in my images: put a layer of saran wrap on my spider. Easily reversible if it has unwanted effects

[harsh matrix]

LMAO

okay i thought i had an example of light spilling over into the frame from last year

but then i noticed

look at how bad i had things a year ago

😭

[frosty shard]

Looks exactly like the flat artifact I had!

(But worse)

[harsh matrix]

that stupid PoS reducer

[frosty shard]

I totally need to hit up M109 though

[harsh matrix]

did it look a little sum like this?

[frosty shard]

Oh no, but you can see the evidence in my IC 10 image

[harsh matrix]

there's dust motes in there too

[harsh matrix]

ohhhhhh

was it the NIR issue?

or was that on every filter too?

[frosty shard]

The greenish halo around the galaxy is from the flats being unusable due to that reflective adapter in my imaging train

It showed up in every broadband image, but it was worse in NIR because I took NIR data at home during higher moon phases

[harsh matrix]

OHHHHH

yeah i had that stupid adapter too for M109

[frosty shard]

In Bortle 3 it was not very significant

[harsh matrix]

apertura should know better

that was a complete waste of our time

[frosty shard]

seriously and it's such a simple fix too. Especially important since M56 adapters are rare

[harsh matrix]

yup

[frosty shard]

I bought another one btw, but that one was also reflective!

(From a different manufacturer, off eBay)

I got it because it was knurled and that makes it easier to remove if I need to, but I just flocked it and it's caused no issues since

You can see it in my NGC 2403 attempt as well

[high aspen]

cat!

[frosty shard]

I really need to get more broadband data on it soon

[high aspen]

yuss

it mini m33

[harsh matrix]

https://app.astrobin.com/i/sivxlq

[frosty shard]

I am also very tempted to do a straight SHO image of M82

[sinful sapphire]

im going to torture the hell out of an EQ6

[high aspen]

whrn u gunna shoot morr

[harsh matrix]

[harsh matrix]

when weather dont suck

[frosty shard]

Once the nighttime low temps are above -10 celsius

[high aspen]

of this

[sinful sapphire]

or maybe ill get a Ragdoll 20

idk if an EQ6 pro can handle a truss RC10

[high aspen]

sad :c

[harsh matrix]

it probably can

[frosty shard]

oh right I should prioritize some Persus Cluster data

[harsh matrix]

they can take a lot of abuse

mine could

[sinful sapphire]

oh i know

[high aspen]

[sinful sapphire]

i saw someone put a 300 PDS on one

[high aspen]

can i file dommnthegears of it

[harsh matrix]

say what now

[high aspen]

i gave up on tyiping

jead hurts

[harsh matrix]

[tulip iris]

Tbh im not the right guy to ask for those things, i use siril thi

[harsh matrix]

extension redesign complete

identical dimensions, just slightly narrower press fit design to comply better with my printer's tolerance

also have gaps in there to let the material bend into position instead of having to be forced in

*identical to the one i downloaded off the web a year ago

cant modify the model directly in fusion

[high aspen]

oo, fancy

[high aspen]

are you gunna flock it

[harsh matrix]

no im going to paint it

it is a perfect fit lmfao

[harsh matrix]

Okay interesting

Something i noticed back with the totally bone stock baffle tubes was that they'd glow bright enough to create a feedback loop between the tubes and the secondary mirror, where the glow from the tubes would bounce up to the secondary and get sent to the camera.

I see no glow from the tubes on the secondary mirror whatsoever.

[harsh matrix]

before and after the temporary solution was removed

right side is with the permanent solution in place and a couple of other things done to remove light leaks and stop internal reflections

that ring in the middle is due to the baffle tube

another coat of paint on some previously painted things too

just more darkening overall but using most of the stock metal parts without flocking

honestly the non ABE'd flat is really clean too

oh god this is a flat with the same system back in may of last year, also a luminance flat

it's so drowned out by stray light that you can't make out any of the features underneath

this is a sky flat

could be part of why

new config is a lot more even

[harsh matrix]

i have not found any examples of people with a tube too long online

[harsh matrix]

was hoping to maybe build a model of the RC by using the radius of curvature in that topic on CN but everyone is assuming the focal length of the system is 1600 mm which is just not correct

i need it to be roughly exact if im going to design a proper baffling solution

[stiff mason]

Wait a minute hubble optics makes a CDK 10inch telescope

Same type of telescope that are super popular like planewave cdk17 and stuff except yk it doesn't weight as much as an african elephant

[tight lodge]

You will have to do some ugly math and scripting in fusion360 to get the radius of curvature of a hyperbola😅

[sinful sapphire]

Yeah

Corrected Dall Kirkhams aren’t that rare

There’s a reason they’re a popular observatory telescope however an RC is still superior

[runic violet]

A CDK in the current market is just a RC that's faster and easier to collimate

[stiff mason]

How so

[sinful sapphire]

No refractive elements

And iirc sharper

Though the optics need to support that

CDKs are easier to manufacture and collimate

A good CDK outperforms an average RC

[runic violet]

RCs are not sharper they're both going to be diff limited

[sinful sapphire]

Oh yeah right 🤦‍♂️

I forgor

[runic violet]

RCs also need refractive elements from a corrector anyways

[sinful sapphire]

mmmm not always

The self correction of RCs is enough for the smaller end of sensors

Though for the purposes of observatories yes you want a corrector

[runic violet]

Running slow is not a great move

Especially for small sensors

[sinful sapphire]

Fair

[runic violet]

So in the end everyone's going to use a reducer/flattener

[sinful sapphire]

Tbf I just generally love the Ritchey-Chrétien design so I’m biased

[runic violet]

Cdks are easier to collimate and manufacture

Because neither mirror is hyperbolic

[sinful sapphire]

Yeah I mean CDKs

Reading back I phrased that really badly

[sinful sapphire]

What shape is the secondary again?

[high aspen]

meeow shaped

[sinful sapphire]

I know the primary is elliptical

Wasn’t it spherical

[runic violet]

yes that's why its so easy to collimate

[stiff mason]

Yeah but at least like CDK are supposed to be aberration free in a large image circle

[sinful sapphire]

CDKs are quite literally uncorrected Cassegrains with an inbuilt corrector

So no different to an RC with a corrector besides the mentioned upsides

[runic violet]

Cdks are generally faster instruments

For amateur purposes they're superior to comparable RCs

The delta rho is even nicer but is a bajillion

[stiff mason]

But an RC with a corrector is the same F ratio

[runic violet]

Cdk14 is natively f/7.2 and goes to f/4.7 with reduction over a larger field anyways

The apex is nice but it doesn't have a huge illuminated field

[high aspen]

what about wynne corrected class casses

basically rasaing a parabolic mirror

[stiff mason]

Isnt it the corrector that makes it f7.2

Also generally speaking most CDK ive seen are more expensive than equivalent RC

Like the 10 inch CDK from hubble optics is almost 5 thousand dollars while a GSO 10 inch RC is about 3 thousand

[runic violet]

There's a reducer that goes on to push it to f/4.7

[runic violet]

No because those aren't equivalents, the equivalent to a Hubble optics CDK would be a Hubble optics RC which doesn't exist

Planewave/observable space makes both cdks and some rcs

GSO RCs are really cheap because they have cheap mechanics and mass produced mirrors that are roughly made

They're a nice bang for the buck but they're not premium grade optics like HO or planewave

Strehl is usually ~0.9 with fairly rough surface accuracy that creates a lot of scattered light

The reason why the high end suppliers don't really make RCs is because the design doesn't make much sense for them since cdks are more suitable, as for why GSO makes RCs is probably because they're not suited to fabricating the corrector and would rather make good enough hyperbolic mirrors

[frosty shard]

This is the Correct Mentality™

[sinful sapphire]

IGNORE facts

EMBRACE Ritchey-Chrétien

[quartz meadow]

BE the chad

[sinful sapphire]

DESTROY refractors

[frosty shard]

ELIMINATE coma

[quartz meadow]

AND be the Knight in shining white armor

[runic violet]

muh noot

[stiff mason]

HO is roughly about the same they have 0.95 surface accuracy

Also I've been looking into the SBIG AO-X and at least on paper it should provide significant improvements in seeing in small to midrange aperatures like 6-10 inch telescopes as their aperatures are small enough that they are only looking thru 1 atmospheric cell which only cause low order front wave errors like tip and tilt instead of high magnitude aka boiling

So theoretically it can provide diffraction limited results for an aperature like a 6 inch

Also it does basically remove any mount wobble as well

Like those caused my mechanical and wind

[runic violet]

In strehl terms 0.9 and >0.95 are very different

~0.82 is the diffraction limit for reference

[runic violet]

It's just a very nice OAG that consumes a lot of backfocus, it does not do a whole lot aside from that

[stiff mason]

I mean

[sinful sapphire]

the kind and humble 0.994 OOUK 12''

[runic violet]

10 hz is not a lot

[stiff mason]

Yeah but still better than nothing

Idk

Ig we gotta wait and see whether a proper AO becomes available to us amateurs that doesn't cost an arm and a leg

[runic violet]

vs an OAG or ONAG, idk

ONAG is probably the better idea

Remember even if you could push to 50 Hz the guide star SNR and measurement is the main limiting factor

Multistar guiding is likely more effective then this anyways on a well functioning mount

[harsh matrix]

[tight lodge]

[harsh matrix]

looks really nice

[stiff mason]

Yes

[stiff mason]

Yeah but a mount cannot fix the wonder of a star

[runic violet]

We're not getting AO anytime soon

What exists for amateurs that costs an arm and a leg is only effective in NIR

Optical AO is extremely difficult

[frosty shard]

This is actually making me wonder

One of the big advantages of the RC design is that without coma, you get minimal field distortion as well and star positions are very accurate (good for astrometry/mosaic stitching without distortion corrections)

[vapid patio]

Is having a permanent pier really that much more beneficial then with a tripod

[frosty shard]

How much of that is negated by the atmosphere

[frosty shard]

I mean in terms of consistent setup and stability, piers are fantastic. But you lose portability, which may be important to you

[vapid patio]

Hmm ok with my bigger setup I wanna make it permanent but wonder how much of a rms difference it will make

I already use a CGEM tripod “ same same as eqr-6 pro”

[desert locust]

im gonna look into this

[runic violet]

What are you comparing to

With a CDK or any glass corrector you automatically have a wavelength problem

[desert locust]

whats the cheapest adaptive optics out there?

[stiff mason]

Well there is like two and it's not really Adaptive Optics it's more of an active Optics

There is the SBIG AO-X and the starlight express one

[desert locust]

I want the one that does atmosphere not mount only

[stiff mason]

Those ones do reduce the effects of the atmosphere to some extent but nothing diffraction limited and also the biggest improvements are for small apertures

[desert locust]

its prob not a worthy buy for me but I will look into it

[stiff mason]

Like

[desert locust]

at 1000 mm it prob wont affect much

[stiff mason]

There is an improvement there

[desert locust]

what was the no correction one

[stiff mason]

Top is no correction

[desert locust]

its says 1hz

[stiff mason]

Yeah 1hz is just normal atmosphere

[desert locust]

oh

[stiff mason]

At least i think

[stiff mason]

Here is the website https://diffractionlimited.com/product/ao-x/

[desert locust]

I wish there was one for smaller sensors

[runic violet]

Also this is a simulation and not real life performance

[desert locust]

ahh

[runic violet]

Real life performance is hard to track down because the only reports come from people with terrible mounts from 10 years ago

[sterile pendant]

I have the AO-7 and even if it does not correct so much about turbulence, it almost erase every little movement from the mount and the scope ! Even if there is a bit of breeze, it can correct it.
So expensive, yes. But you have in return an almost perfect mount !

[stiff mason]

Which in of it self will improve image quality

[desert locust]

so guiding on steroids

[sterile pendant]

I even tested using the raquet at low speed and found it can correct it 😂

[sterile pendant]

Pretty much

[runic violet]

It's a really good oag

[desert locust]

whats the raquet

[sterile pendant]

Also, the 10Hz isn't the limit ! It depend on the sensor used for the guiding. And at the time, it was pretty terrible... Nowadays, you an litteraly film stars

[desert locust]

wdym film stars?

[sterile pendant]

Sorry for my english.... I want to say the telecomand ? The racket ? The thing to move the scope

[sterile pendant]

I know a project and it goes at 150fps

[desert locust]

oh

is this the same thing but for smaller sensors? https://diffractionlimited.com/product/ao-8a/

[stiff mason]

Controller*

[runic violet]

Tip/tilt frequency is 10 Hz

That's the limit

[sterile pendant]

Yes, the main problem is always the mount in a first place. It is everytime worst than everything else

[runic violet]

The ao-x can allegedly go up to 50 Hz

But it doesn't matter because you're unlikely to have the requisite snr in any given position

[stiff mason]

There is a guy on YouTube who made his own deformable mirror lol https://youtu.be/TPyQI7bJo6Q?si=AcSWEUPP4ZdRd9wO

[sterile pendant]

No, you can go at 15Hz actually when you have a bright star

[desert locust]

what if you had an ONAG

or do ONAG's not have brighter images?

[sterile pendant]

Yes, good demo, but not good enough for now... I can't wait the evolution of this project !!!

[runic violet]

This is not a limitation imposed by the star necessarily but by the mechanics

[sterile pendant]

https://www.btregon-astro.org/compensateur-de-tip-tilt/

[sterile pendant]

My correction was 15Hz I assure you 😅

But most of the time you are stuck at 5fps or less...

Because of the low sensitivity of the old sensor

That is why ! I will modify my AO-7 to adapt with a modern optic divisor !
Like this, I am not always forced to use the SBIG S-T7. Good guy, but he need some rest at that point 😂

Only damn problem, the long backfocus... But, with a Cassegrain, no more problems !

[high aspen]

he made a glass ceramic mirror too :D

i love that guy!!!!

(he was the one that inspired me to look into ray optics)

[frosty shard]

@harsh matrix do you know offhand what your backlash compensation is for your Gemini EAF?

I may pull my rig out and I want to set some sane defaults for autofocusing

also do you use the Hocus Focus plugin?

[harsh matrix]

I do

[harsh matrix]

85 out

[frosty shard]

And do you know your step size for autofocus?

[harsh matrix]

Not at the moment.

[tulip iris]

@harsh matrix Id like to get an oag, any ideas on which one?

[frosty shard]

Do you have a filter wheel?

The SVBONY one is fine in that case

[harsh matrix]

I really like the QHY OAG-M Pro but you need a specific filter wheel to use it.

I like the Askar OAG quite a bit too but the Svbony one might be better value

[tulip iris]

Nope

[tulip iris]

Ah i saw it

[tulip iris]

Yeah maybe

How abt zwo one?

[alpine flame]

Antlia has a OAG + filter drawer combo

Liek a single adapter thats an OAG and a filter drawer at the same time

I know its really rigid cause its cut from a single block of aluminium

Im not sure how much is costs tho

[tulip iris]

Ill give it a check rn just wait

305 bucks

[alpine flame]

Well

Not great

But not a lot more expensive if u got an OAG and a filter drawer separately

The OAG L itself from ZWO costs 250 eur here

[tulip iris]

Yeah…

[alpine flame]

@tulip iris Maybe it would be worth it to consider it

[tulip iris]

If u get the L one yes

I was considering the standard too

But idk if an rc6 w a 120mm mini can work w that

[alpine flame]

120mm sensor is fine for the standart OAG

But bigger prism more light

Id get the L, its safer if U wanna upgrade

[tulip iris]

Yeah i thought abt that

[tulip iris]

Thats right

Atp id get the the svbony one but ehhhh

Idk last time i got a svbony thing was the canon t ring and the tolerance space between thr pin that locks the bayonet and the rest of the body of the t ring was just too much

Since that moment i stopper buying svbony

[runic violet]

I would really get a more modern sensor

Oag at high FL with that only really works in the Mw

[tulip iris]

Asi 220 is okay?

[tulip iris]

Pls dont tell me i have to buy a 400 buck sensor

[runic violet]

290 is more modern

[runic violet]

220/sc2210 is the second best thing you can get

[tulip iris]

It costs 400 bucks

I dont wanna spend this much for a guide camera i wont use for anything else

[tulip iris]

Mhm okay, even tho i heard its more sensitive but w oag maybe not too great

[silver ibex]

Maybe he can get a 178?

I use one, it's ok

[tulip iris]

178 its another damn expensive one

Aint it an old sensor too?

[silver ibex]

The player one should be 300€ after taxes

In Italy

[tulip iris]

Yeah i know thats the one adviced for oag but its crazy, i should spend in the best case 600 bucks

[tulip iris]

300?

Uanm e a rov e pigliat😭

[silver ibex]

Sedna-M

[tulip iris]

My bad

[silver ibex]

Direttamente dal sito della Player One

[tulip iris]

Ah now makes sense

[tulip iris]

Colgo l’occasione, sono compatibili con le zwo? Pk tengo la 533 da poco

[silver ibex]

Sono due cose separate, non si interfaccia mai con la fotocamera principale

Se invece intendi se è compatibile con asiair, boh

[tulip iris]

Forse é meglio discute in privato se in italiano btw magari qua si triggerwno che ne so

[high aspen]

use a 585 as an oag cam

[silver ibex]

Bruh

[tulip iris]

Bruh

[high aspen]

[silver ibex]

Put a filter wheel on the guide camera too

[tulip iris]

Ill go for the 2600 atp

[silver ibex]

And an oag in the guide camera's path

[tulip iris]

U forgot the flattenet

[silver ibex]

OAG inception

[high aspen]

my 585 is gunna be my guidecam :3

[silver ibex]

imx455 as a guide camera

[desert locust]

is imx 585 anygood for a guide cam

[silver ibex]

Completely overkill imo

In bigger telescopes it makes sense though

[tulip iris]

Imx 461

[silver ibex]

Like, I can see that being used in, say, a 14" RC

[tulip iris]

Thats the point

[desert locust]

I have a uranus c, and I might get an rc, Im gonna upgrade to uranus m pro, so a 585 seems good

rc by rc 8 or 10

[tulip iris]

Im just broke guys dont say those things🥀

[silver ibex]

It's not 1.25" though

[silver ibex]

You'll need some adapters

[tulip iris]

Dont do that, or at lesst if so consider u gonna spend at least double the price of ur scope

[tulip iris]

I have rc6

[desert locust]

for the rc 10 compared to 8?

[tulip iris]

Indipendently by the sizw

Its the rule of thumb of rc scopes

If u plan on going cheap forget that

Its not gonna happen

[silver ibex]

Yeah, the difference in price between 8 and 10 is insane

[runic violet]

It's the best

[tight lodge]

585 is good all around.

[desert locust]

if im gonna get a 10" scope it will be an rc 10

but 8" would be f/5 newt

rc 10 like 2200 right?

or I could get an sct from cloudy nights

[harsh matrix]

guys I won't lie

this is pretty darn good

for data with a moon out

and some passing clouds

i deleted the subs i could see clouds in but as i forgot to blink and delete as i went, i had to pick them out in WBPP SFS

yeah i think it stacked some clouds

really not bad then

[frosty shard]

Damn the full moon really do be ruining images

[harsh matrix]

nothing

no dust

i think some of this weirdness is because i may have had high cloud all night without knowing

a little bit might be ifn too 💀

[harsh matrix]

that is what it does best

but it cant seem to ruin them much more than giving me a strong gradient now

that's 3 hours and 21 minutes of data

cant wait to see what else this scope cooks up tbh

[harsh matrix]

I did get a teeny bit of IFN

the small slightly lighter fuzzy patch above this star

I'd say this was the most successful test in months

it's essentially flawless

no glaring issues

other than the clouds

@frosty shard how's that collimation

i dont know how it's this low at all

my corners look awful

[frosty shard]

Is that native FL?

[harsh matrix]

looks like I have unbalanced off axis astigmatism

[harsh matrix]

no it's with the reducer

i hate the reducer for one reason only

it makes collimation an utter nightmare

[frosty shard]

I wouldn't even bother with any adjustments at that point tbh

[harsh matrix]

me neither

except if i put the 571 back on here

this will be horrible

[frosty shard]

The seeing must be pretty bad then if those are your HFRs

[harsh matrix]

luckily that big sensor should make it easier to identify what adjustments need to be made

[harsh matrix]

ASTAP always estimates really high

[frosty shard]

oh it's also estimating on the M81 nucleus too

[harsh matrix]

Pix was saying my average FWHM for the night was around 3.96 pixels

[harsh matrix]

yes

it's not very smart

2.89" FWHM

oh you know what else it could be

i figured out my back spacing for reducer elements with the ZWO EFW and Askar OAG is way off

im 3.5 mm over 55 mm back focus

this is where the back focus is with the 533 and the apex

so i need to find some way to shave off 3.5 mm

[harsh matrix]

okay

RC picked up IFN

that's a first

not a small amount either

the background is filled with it

I did another round of DBE thinking it was something I missed

no, that was all IFN 💀

it looks like cloud haze or something

that's a first for either of the RC's I have owned

usually when I shoot a spot I know has IFN, the IFN gets buried under a mountain of other problems which makes identifying the stuff impossible.

plus, those problems created a massive SNR issue

now with a shorter baffle tube extension, I'm using more of the primary, which made the scope even faster

guess I just forgot how much there was here

my frame is literally all IFN outside of Bode's

[sinful sapphire]

Ceres-462M costs like 180

Unless you had the unwise decision to get an asiair

[harsh matrix]

@sterile pendant at this moment in time, it appears that the cause of all of my troubles... was the stock baffle tube extension being 25 mm too long... from the factory.

[runic violet]

Bruh

Properly modded newt > GSO rc > cheap newt >>>> regular sct >>>> edgehd imo

[high aspen]

i thought the tube was too long!!!

[high aspen]

i think you got some ifn

[sterile pendant]

Aaah !
Interesting !
And now everything is resolved ?

[harsh matrix]

seems to be

[sterile pendant]

Do you think it is possible there is the same problem for the 6" ?

[harsh matrix]

nope

my Carbonstar RC6 did not come with an extension and had obvious light leakage issues from around the secondary mirror

the tube was only 150 mm long and did not have any extensions

afaik the 6's do not come with an extension from the factory

but my 8 came with an extension long before they were standard and it was just cut out to be 50 mm long which just so happens to be too long

[sterile pendant]

Damn 😭😂

It took a bit of your time this problem 😅

Hopefully, it look like the end

[harsh matrix]

way too much of it

luckily it seems to be done eating up my time

now it is time to put it to use

[sterile pendant]

Do you have some clear sky ?

[harsh matrix]

Yes

[sterile pendant]

What a luck…

[tall summit]

I can confirm that

[tulip iris]

Wow das crazy

How much integration?

[stiff mason]

What mount you gonna use

[stiff mason]

Damn

[harsh matrix]

3 hours and 21 minutes

[frosty shard]

I might finally get to image again tomorrow

Hopefully checkout of the autofocuser won't take too long

Tbh, worst case I can just find focus with the Bahtinov mask and then mess with the autofocuser after moonrise

[desert locust]

whats wrong with scts?

[desert locust]

if I get a 10" ragdoll 20 pro or regular ragdoll 20

[stiff mason]

Ooh same

[desert locust]

I alredy have the ragdoll 17

[stiff mason]

Nothing really they are pretty much the swiss army knife of telescopes you can use them at f2 or f8 both at native fl or add a reducer and use it at f5 they are super versatile but the optics aren't as good and clean as say an RC

[stiff mason]

What's your guiding like

[desert locust]

I havent got guiding yet

[frosty shard]

Many SCTs have stray light problems because they're not really baffled

[desert locust]

ah, ok

[digital nexus]

Spend the extra for the pro

The features have saved me lol

[desert locust]

I know they have better pe, but what else

[frosty shard]

exhibit A:

I have seen this artifact in almost every SCT I've used (visually)

Even the EdgeHD versions

[digital nexus]

Physical limits/sensors. it’ll always find home regardless of what software say. So I use the button to force going home when my software messes up.

[frosty shard]

An advantage not to be understated

[stiff mason]

Why not

[desert locust]

just got the mount recently

[stiff mason]

What is your guiding like

[high aspen]

ah yes the

[stiff mason]

Oh nice

[high aspen]

o)> artefact

[digital nexus]

I’ve only used it like 5 times. And I kept swapping guiding

I’ve tried a 30mm guide scope. 50mm, and an OAG.

So I don’t have long term data, but so far I’ve gotten it to be around 0.5-0.7” my recent session. This is with the OAG. I’m still tweaking my settings of course.

[stiff mason]

Damn yeah those SCTs will not survive a second in bortle 9 lol

[frosty shard]

Imagine shooting the honse with one

[stiff mason]

What about tracking what is the longest sub you've taken with it

[stiff mason]

Imagine having a bright street light 10 meters from your telescope

[digital nexus]

5 minutes. I haven’t attempted anything higher since I typically stay between 2-5 regardless

[stiff mason]

What about FWHM how good has that been

[digital nexus]

Haven’t looked at it. But that’s more affected by your scope and camera combo

[runic violet]

They have no redeeming qualities for deep sky compared to RCs

[stiff mason]

Your mount wobble will play a big role in it as well

[runic violet]

The only thing here a sct can do that a newt can't is f/2 and the optical performance there is poor

[digital nexus]

yea but since my scope/camera is different from yours idk how useful it would be. But either way I haven’t checked

My seasons all been meh cause I’ve had technical issues

Recent session was great but my EAF didn’t work in -3F. So I threw out the data :/

[stiff mason]

What scope and camera do you have

[digital nexus]

Askar 71f and 533mc pro

I haven’t used my RC6 yet

[frosty shard]

The artifact is worse when there's a bright star in the field than when you have streetlights around (assuming you don't point near the streetlight)

[stiff mason]

Fair

[stiff mason]

You should

[digital nexus]

I can’t

I was waiting until I know guiding is 100% good to go. It’s also cold AF. I’m not learning how to collimate this thing in -8F. Like that ain’t happening.

I got a reducer from brain so that’ll make me more confident on guiding though

Also gonna get an EAF for it

[runic violet]

Almost every aspect of SCTs is worse compared to a gso RC, from strehl to contrast to CA to even mechanical stability, field performance can be comparable if you leave the sct at f/10 (edgehd) otherwise it's worse

[tulip iris]

What

Why my 4hrs look shit compared to yours 😭

[harsh matrix]

12 hours of LRGB

bad DBE on the lum, idc rn

[harsh matrix]

because mono is unfathomably OP

[tulip iris]

Looks very nice actually

[tulip iris]

Ah i forgot u use mono

[harsh matrix]

it has some color balance issues, mainly because my red channel has far better signal than green and blue

so there's always a red bias in my broadband from home 😭

[tulip iris]

Yeah but doesnt matter tbh

Result is very promising

[stiff mason]

Indeed

[tulip iris]

Can somebody gimme a tip on what settings should i use when dithering

I feel like im not doing it correctly

[versed roost]

how does one pronounce ritchey chretien

[tall summit]

for what its worth, I personally dither every 3rd frame by 5 random pixels

[desert locust]

hope and prayers

[vapid patio]

dang doing great

mono really shines with Ha on galaxys

in rgb aswell

[vapid patio]

Rich-ee Kray-tee-en

or like

Kray-tyan

[tulip iris]

I do every 3 frames but by 8px

[stiff mason]

Creatine?

https://tenor.com/view/flexing-flex-arnold-arnold-schwarzenegger-body-builder-gif-18454197

[high aspen]

that is not just from creatine 😭

[stiff mason]

Ik

But creatine does help in muscle building so

[harsh matrix]

i expected a single blue sub in my yard to be completely devoid of life

but no

quattro f/3.45 go brrrrrr

the quattro is the one thing that may restore my hope for HaRGB type images

[harsh matrix]

uh okay

pop off

got a few issues but I wouldnt say it is unusable

GYATTT

I did use sky flats and some clouds snuck into those which wasn't supposed to happen

so that could be a minor part of it

not a deal breaker since I plan to crop a little anyway

[high aspen]

nb or bb?

[harsh matrix]

Broadband

paracorr is here now

gonna try to squeeze in first light after this sets tonight

we will see if all of this weirdness is fixed or not (with the 571, the 585 will probably be perfect)

[high aspen]

thats pretty

mini gradiens

tho

[harsh matrix]

Yes

Unavoidable with the current config

They might be gone with the paracorr

[high aspen]

we can ony hoep

the paracor looks silly, isn it meant for eyepeices?

[harsh matrix]

It can do both visual and imaging

Paracorr V2 specifically

[high aspen]

oo nice

[frosty shard]

Welp. My dreams of imaging tonight appear to be dashed. Wind just massively picked up

[harsh matrix]

Did you ever measure the baffle tube?

[frosty shard]

Oh right I'm gonna see if I can do that

I am at the club dark site so idk if there is tooling to do it here, but I'm gonna have a look

Also the autofocuser does work!

[harsh matrix]

Get ready for the best FWHM's you've ever seen

[tight lodge]

Whenever it's not windy

[frosty shard]

Even with this wind...man I should have done this earlier

[harsh matrix]

woooooowwwwww

@high aspen I got a better DBE

no more weirdness

also cropped out the corners because they seem to make it way worse

[tight lodge]

I should really have a close up look of it

[harsh matrix]

Yes you should

And then maybe we can do another collab to try to steal IOTD

[frosty shard]

I was thinking about imaging the Parade of Animals

[frosty shard]

A little more data on Abell 426

[harsh matrix]

@tight lodge Paracorr first light is here

post DBE

the remaining weirdness should easily correct out with flats

My RC basically has this exact artifact and that appears to take care of itself now

even when it doesn't, I can suppress it with DBE enough for it to not matter anymore

it should handle the 585 flawlessly

that's the hope

[high aspen]

looking good

[high aspen]

oh wow, thats like really good

[harsh matrix]

yeah

especially considering the moon being out too

not sure what the dark part is

seems like it was present before but always calibrated out possibly?

and if it isn't, I haven't popped my ultimate on this scope yet because the stock CC was longer than the focuser draw tube

I can still paint and/or flock the drawtube

[high aspen]

maybe something on the secondary or primary?

or on the sensor?

[harsh matrix]

definitely not on the sensor

and there's not a big enough splotch of something on either mirror for it to be on the mirror

what's confusing is while it looks like it was present before, it didn't seem to change shape or size whatsoever

[high aspen]

buh

sensor damag?

[harsh matrix]

no

it isn't present on my redcat and it's a totally different size/shape/position on the RC8

whatever it is, it doesnt appear to be in my imaging train

it appears to be with the scope

ohhhhhhhh boy

what if it is the dew shield

I captured something entirely unrelated

i dont know what this was or how to identify it

back to back lum subs that were 3 minute long each

[frosty shard]

Where in the sky?

[harsh matrix]

next to M106

M106 is in the right half of the frame

if it was a plane it had to be slow asf

so probs not a plane

[frosty shard]

Probably not tumbling satellites either

That is a wildly small scale

[high aspen]

line!!!

[frosty shard]

speaking of small scale

[high aspen]

ama say smol debris that exploded

[harsh matrix]

yes there's a line

[harsh matrix]

but exploded twice?

why would it be the exact same magnitude 3 minutes apart?

[high aspen]

waiit whaa

[harsh matrix]

and not the whole way through the frame?

[high aspen]

huuuu

thats weird

[high aspen]

first time was bright enough to give itself spikes

diffraction spikes

[harsh matrix]

yes

can still see them in the second frame but they're total ghosts

wow honestly

very impressive

very

now @ 9 hours of broadband on this thing

w/ a quite well managed background all things considered

[high aspen]

insane detail

[harsh matrix]

am sniffing this out with blue light filter on so... don't go too hard

[high aspen]

i a lot of the time end up doing that

[harsh matrix]

I expected all of these tiny filaments to be complete mud due to the light pollution

I am very happy they are not

this should make a very nice HaRGB image

maybe Sii if that data was good

[high aspen]

i think 850nm is almost uneffected by light pollution

bc the atmosphere looks completely black

[tight lodge]

Is this with the 571?

[high aspen]

hubble var neb is gunna be fun with my 850nm filter

i wonder if the ir data is being used to subtract from the g filter

the diff in dustyness is crazy

[tidal hearth]

Soooooo

Mr pickles made me get interessted in rc

Originaly i wanted a celestron c8

Is a omegon carbon 203/1624 good ? Costs around 1500€ and i will decouple it as he told me

[high aspen]

i think most gso rc's are built the same

[tidal hearth]

As i understood by what he told me i dont need a corrector when using a 585 or 571

[high aspen]

you shouldnt need one no

you can run native no aberration

[tidal hearth]

Amazing

About collimation, is it any different then on a newt?

Bc i used a newt for being mobile and it didnt work for me since i allways had to recollimate… so i sold it but now i want something with much focal lenght xd

[high aspen]

yea

star collimation is the way

[tidal hearth]

I mean i got a ocalˋ

So its better for me to star colli, alr

[high aspen]

i think you can use that to start with the alignment

sometimes they come collimated a decent way so you should check that too

[tidal hearth]

If i buy it teleskop-express.de they will collimate it before shipping

So it should be easier to collimate it when i get it

Any upgrade you would perform except decoupling?

[high aspen]

https://app.astrobin.com/equipment/explorer/sensor/152/sony-imx183-mono?i=np6ffd

way

660 hours and no awards or anything

[tidal hearth]

Ahahahah

But that Ha damn

[high aspen]

honestly dont know

i would like an rc bc its a decent scope

[tidal hearth]

What i thought about is adding 2 heatbands for the mirrors and 3 fans on the back for cold air

Simular to this

[high aspen]

the fans is a good idea

[tidal hearth]

Prob gonna order my rc at end of autumn

Before that i want a askar103 so i can still drive around without worying of collimation (ik im a bad guy)

[high aspen]

i clean mai mirror :3

even had flash on

[tidal hearth]

Please get a mirrormask

.-.

[high aspen]

soon™

[tidal hearth]

Backyard universe got you covered ma guy

[crisp flower]

It clean

[runic violet]

No you need it for a 571

[crisp flower]

Its the RC i got and im pretty satisfied with it

Did they get more expensive tho? Because Mine was about 500 less :/

[runic violet]

You don't need it for a 533/585 at native but I would not use it at native because especially with the 585 that's basically oversampling

[tulip iris]

Hows it possible, ive been checking prices every like 3 days and its always been around 1500 the carbon 8”

[runic violet]

I mean, a decoupled rc holds better than most newts but is more frustrating to collimate, a nondecoupled rc is a can of worms depending on heavy the image train

[tulip iris]

The steel tube is 1000

[crisp flower]

Because i cant read 😭

I have a Steel tube thank u for pointing it Out!

[tulip iris]

Dw

[tulip iris]

Thats what i thought

@crisp flower How good is the one u have? I got the smaller 6” but literally i need to change everything

[crisp flower]

Tbh im in Love with it
I Had some reaaaally big Problems with it in the beginning because i was using the wrong Method to collimate it but ever since i got it right i have Had No issues and its performing great

[tidal hearth]

Alr

[crisp flower]

Except of some relfections i Had in my Images but those we're caused by shiny surfaces in the extention Tubes of my 533

[tidal hearth]

I will add a mono 585 with filterwheel and oag 😂

[crisp flower]

I have Not used it since i got them fixed but soon i hope

[tulip iris]

Like, same tbh, no i did the mistake that when i bought it i was slightly clueless abt the flaws of the system so i soon figured out the focuser and shi like that, other than that same, even tho idk if my collimation is good cuz i never collimated it since i got it

[runic violet]

I would 100% slap a ccdt67 on that

[tulip iris]

Shiny sufraces in the 533? What i use them too but i i didnt see anything

[tidal hearth]

Well thats not the reason why i want something with much focal lenght :/

[crisp flower]

The First time i got it it took my over a month to get it right but now its fairly quick

Theres also Not really a need to recollimate because it holds it so goddamn well

[runic violet]

There's not much point to that focal length with such tiny pixels

[crisp flower]

Nono the extention Tubes Leasing to the camera system

[runic violet]

Can't beat seeing nor physics nor any mount limitations

[tulip iris]

I think i can agree cuz mine is here since 2 yrs and i havent collimated it yet

[tidal hearth]

I will prove u wrong xd

[tulip iris]

Even tho 1 yr i didnt really use it bcz i havent got time

[tidal hearth]

I already proved many wrong with my saxon heq5 that is 21 years old

[tulip iris]

Which ones u talkin abt? Rc ones or zwo?

[runic violet]

I mean look at your current fwhms / guiding numbers

[tidal hearth]

And 600mm apsc no guider 3 mins exposures with almost perfect stars

[tidal hearth]

I get down to 0.2 total with a 21 yo heq5

I will buy a ragdoll 20 pro

[runic violet]

0.2 arcsec?

[tidal hearth]

Uhhh

[crisp flower]

Neither
I have a touptec rebrand

The surfaces within the RC are all fine but every single one from the camera and Guide Cam are shiny

[tidal hearth]

Its just 0.2 and the (a number with ´with ´

[runic violet]

0.2 doesn't mean much without units

[tulip iris]

Ah okay, yeah it can happen tho oof unlucky

[runic violet]

But you need to figure out what your limits are before just deciding to go for a billion mm of fl

[crisp flower]

Yea i guess

I dont know how Long i wouldve Run around with These If @frosty shard didnt hint me towards em

[tulip iris]

Btw i think hes referring to the number on the left of the arcsec values, like idk what unity is that, its just a number

[tidal hearth]

This was with my 21yo heq5 the worst number i see in nina

[tulip iris]

Do u use the 533 on native fl?

[crisp flower]

Yessir

[tulip iris]

Just cuz i do lmao, idk maybe too much oversampling

[tulip iris]

I feel like im doing somethibg wrong

[crisp flower]

Why

Why so U think so*

[runic violet]

Whats your guiding setup

[runic violet]

Pixels

[tidal hearth]

Oag with a gpm462m

[tulip iris]

Mathematically if u got an aversge fwhm its oversampling but idk, ngl sky fwhm changes day to day so i dont stress too much abt it

[tidal hearth]

This still has 21yo bearings and grease

[tulip iris]

Exactly thanks i lowkey forgot abt rhat

[runic violet]

What scope

[high aspen]

mine moves 0.3 pixels but that dont mean shit when its actually moving 0.45 arcsec

[tidal hearth]

That was when I had my Quattro 150p reduced to f3.45

But now I run a sv555 😅

[crisp flower]

Got it
Im Not looking too hard on fwhm atm (i think im having some issues with my collimation and These are adding to fwhm i think)

[high aspen]

if i get an f4 scope amma reduce it to f3

0.75x cc

[crisp flower]

Whyd U Switch from the 150p?

[high aspen]

wants to collect less light

[tulip iris]

I may actually be affected by the same, ngl i dont have the tilt backplate plus im still sticking w that linear crayford focuser they privide it w which is ass and doesnt even have a screwable side so i have to use compression ring lmao

[tidal hearth]

Bc I wanted to stay mobile and only had one scope

And as a apprentice I didn’t had much money for a second scope setup

So I sold the Quattro

To get a sv555

[tulip iris]

[tidal hearth]

But now since I’m done with my apprenticeship I want to get back in for a second setup that will stay at home

[tidal hearth]

[crisp flower]

Im also running everything Stock
Im thinking im having issues because i could Go to about 1.2 average Star size when doing an Autofocus Run and now i am averaging about 2.1

[runic violet]

But what's the best

[crisp flower]

Xddd i got it but i still think its sad

[runic violet]

And have you measured fwhm

[crisp flower]

I feel that
Sold my beloved phq80 and c8edge for the RC and some extra

[runic violet]

585 native on rc8 is 0.37"/px which requires 0.7-1" seeing which you don't really get almost anywhere but the most topographically perfect places

[tidal hearth]

Got no pic but I remember is 0.42‘‘ or so

I average around .6-7

[runic violet]

So unless you are getting 1-1.5" fwhms frequently enough this is too much FL for that cam

The guiding number only tells me the mount isn't a huge problem

[tulip iris]

[tidal hearth]

Well at some positions it got some problems xd

[runic violet]

It could be better but it's probably going to be better with higher FL oag

[tidal hearth]

That’s why I need new bearings

[high aspen]

was the rc worth it tho

[runic violet]

c8 edge is no loss

[tulip iris]

At least u got the linear bearing focuser right? Does it slip or is it fine? Lmao i thought my issue was that a 850g dslr was overload but slipping even when using a 533 without cables is lowkey crZy

[tidal hearth]

Well 21yo

[tulip iris]

Wait u forgot to mention the part where its 21 yo

Im jk

Btw for that age rms aint bad at all

[tidal hearth]

Fun fact it got a skywatcher heq5 sticker on the side but it was sold under Saxon

[tulip iris]

Why havent u thought abt getting a rowan belt mod?

[tidal hearth]

It runs amazing? So no need to change it now

😅

[tulip iris]

Mhm okay but it could be better than amazing too w that

[tidal hearth]

The problem is I looked it up

[tulip iris]

Just smoother movements yk

[tidal hearth]

And this is lot the same as the skywatcher heq5

This one is still a Saxon

[tulip iris]

I didnt follow up really, whats the issue u gotv

[tidal hearth]

And even the bearings are different size

[tulip iris]

Ah so no compatible

[tidal hearth]

I need to find one fitting the Saxon heq5

Go finding one

[crisp flower]

100%
Tho i still Miss the phq

[tulip iris]

Ah atp just stick w watchu got and change the mount definitely

[crisp flower]

Bit i cant use two big Setups atm

[tidal hearth]

Yep will mainly use the ragdoll 20 pro then

The heq5 will stay at home when I wanna go somewhere else

[crisp flower]

It doesnt Slip i thonk

[tulip iris]

Why go harmonic? A good ol eq6r never disappoints

Has better pe too

[tidal hearth]

Ragdoll 20 pro is a am7

But cheaper

[crisp flower]

Except when it Burns a hole in its Motherboard Like Mine did

[tidal hearth]

For 2000€ I will get the ragdoll with tripod and pier

[tulip iris]

Okay, cuz im researching a good focuser to switch mine w and idk i just found 350€ ones, my wallet

[crisp flower]

It Worth tho

[tulip iris]

Whatever it is, its harmonic, well idk if u count on portability and no worries abt weight balance okay

[tulip iris]

Shortcircuit?

[tidal hearth]

Also i want it for portability

[runic violet]

Harmonics only make sense for portability and not much else

[tulip iris]

Crazy i have my gem28 rocking and its all great

[tulip iris]

Ik, any tips for the focuser by any chance? Idk which one to buy😭

[tulip iris]

Unless its for that i wouldnt advice it

My overloaded mount tracks better than any harmonic u want, unless u talking abt things such as a wd20

[crisp flower]

Probably

[runic violet]

Baader steeltrack hehe

[tidal hearth]

Well I got the tools for smd soldering

[tulip iris]

@runic violet just cuz ur here atm, native fl rc6 and 533 is good or should i buy a reducer?

Nope tbh
I Heard of some that are great Here but i cant remember their Name xd

[tulip iris]

Crazy tho, humidity shouldnt get into those places

[runic violet]

I will always advise a reducer because 99% of the time the FL is not terribly useful and the increased etendue/fov is more useful

Unless you find yourself on an ocean plain or on a tall mountaintop lol

[tulip iris]

I didnt find any proof of people attaching it to rc scopes, like i checked the markets here and all the ones they sell are for scts and newts and fracs

[tulip iris]

It aint that easy

[tulip iris]

Okay dw!

[runic violet]

Googled and I found them

It's the Baader m90 adapter that you need

[tulip iris]

Is it really like that?

[runic violet]

If you want the reality check measure your fwhms

[crisp flower]

Yup
Was really confusing to See ngl

[tulip iris]

My height relative to the sea is 100m🤣

Idk dude i swear id trust whatchu say

Ccd67 or gso reducer?

[runic violet]

Do you think you have good seeing

[tulip iris]

The model tho, i gotta buy the refractor one?

[tidal hearth]

I repaired a brpken stellavita, asiair plus and upgraded vram on a rtx 2070 super

[tulip iris]

Otherwise i was thinking abt a ts one which is 350 bucks but seems good

[runic violet]

I doubt the ts one is worth it

[tulip iris]

I feel you, sometimes is good to give a look at your stuff, i usually do a check on the insides of the mount, like i just check the engine covers belts and motherboards

[runic violet]

Unless I'm grossly underestimating the cost of a steeltrack for you

[tulip iris]

Tbh it depends, on some nights meteoblue says i got even 1 arcsec of seeing

[runic violet]

Don't worry about refractor, your RC uses a m90x1 thread

It may be marketed towards skywatcher fracs that also use that thread but it's the same thread

[tulip iris]

If u want i can send u a screen of what weather app says atm, even tho its raining so

[runic violet]

Meteoblue is always wrong but the fact it says you get 1" at best tells me enough

Most people get like 0.3-0.5" out of meteoblue because it's so dumb

[tulip iris]

Its this one, just to show u atp

[runic violet]

So I'm guessing you don't get very great seeing

[tulip iris]

Tbh i have no idea

[runic violet]

Wouldn't recommend

That thing floppy

[tulip iris]

Nah i trust watchu say

[runic violet]

Maybe what it needs is loctite to work properly but not worth the risk

[tulip iris]

Okay so i just get the m90 flange thats what matters

[runic violet]

Don't, search the cost
