Ritchey–Chrétien enjoyers thread

[harsh matrix]

It is designed for the RC

Ive heard people ask about those before but I havent heard much about how well they work

[high aspen]

you got it?

[digital nexus]

I bought it

[harsh matrix]

What i can say is it looks to be built like an absolute tank

[high aspen]

based

[digital nexus]

He ships it Monday

Another link

[digital nexus]

How’d you know it’s made for the rc?

[harsh matrix]

People talk about whether or not they should buy these for their RC's all the time

Also it is M90

Same thread used by the stock focusers and all of the extension tubes that come with the scope

[digital nexus]

ok. Sounds like these focusers aren’t sold anymore

Is it a feather touch?

[tall summit]

Went trough a mirror cleaning and collimation last night

[high aspen]

spikey

[tall summit]

tri-Bahtinov mask

didn't have opportunity to test on a denser star-field, does it look collimated enough?

[high aspen]

uhhh

maybe?

[harsh matrix]

Nope

[harsh matrix]

Looks good at a glance but you'd need to crop in on stars in the middle before I could tell you definitively.

[digital nexus]

@harsh matrix You decoupled your RC? how did you do that

[harsh matrix]

I bought a new decoupler design from TS Optics, I had to drill holes in the aluminum back plate

There are no decouplers available to the RC6, to my knowledge

[digital nexus]

I found a 3d printed one

I could prob get that made in metal ?

https://www.thingiverse.com/thing:6257205

[harsh matrix]

Maybe?

[digital nexus]

either way not sure im comfortable drilling holes

somebody on CN does it for people i think

[harsh matrix]

Yes

I dont believe he makes one for the 6 but I could be mistake

I wasnt comfortable drilling holes either but I did it

Like I said, its not really necessary for a light OSC setup

[digital nexus]

somebody with a 2600mc / filter drawer had problems

[digital nexus]

idk if youd consider that light or not

[harsh matrix]

I wouldnt call that light

[digital nexus]

bro why is it so ugly

[harsh matrix]

@frosty shard the seeing at Starfront is equivalent to mine

I dont believe i can afford a pier there, right now, but if I can nail a good job, I would be able to do it.

That would be where the RC8 goes

It is by far my most ironed out rig with the least amount of issues (it did perform quite poorly last night, worried polar alignment slipped, not something worse, could have been wind too)

[undone sedge]

i would definitely get a rotator if you send it out there

...and go personally for the install too so you can make sure stuff is right

[harsh matrix]

I plan to do that

[harsh matrix]

I am thinking that is necessary too

[frosty shard]

heh if you have space and they allow it, bring the Dob too and enjoy the dark sky

[harsh matrix]

Back focus is going to be hard

[harsh matrix]

That would be fun asf

[undone sedge]

i know a guy who has a svx90t there and, a few things:

a) no rotator so they had to manually set the rotation, took them a couple tries (it slipped though so he needs them to redo it now)
b) a cable got unplugged and it took them 3 days to get to it

i've heard the cable management they do there is awful

so yeah.

[harsh matrix]

I have heard that too

That's a reason id like to go in person to drop it off and watch set up

[undone sedge]

yea

[harsh matrix]

I would like to figure out a permanent cable management set up too.

[undone sedge]

i would too, even though i'm halfway across the country yk

[harsh matrix]

Probably need to relocate the mini PC and get a power box that is remote controllable too.

[undone sedge]

this

the wanderer plus is a good value imo

software is nice, comes with a temperature sensor too

[harsh matrix]

I forgot about the wanderer stuff till I saw a flat panel on CN that is 250 mm for 350 bucks

Very good value as far as large flat panels are concerned.

[undone sedge]

agreed

[harsh matrix]

Yeah so I got some more things to solve with the RC8 then

[undone sedge]

i'm wanting a couple rotators for my 102s just so i dont need to turn the entire focuser

[harsh matrix]

I think i need to include the dew shield too

I dont trust no dew shield there, where I cant fix dew problems if any arise

[undone sedge]

will let me not have a headache with my cables every time i change rotation, since my powerbox is on the focuser (finder shoes)

[undone sedge]

yea that too

[harsh matrix]

Hmmmm

I forgot that cables can twist and stuff with a rotator

[undone sedge]

the temp sensor on the wanderer box does humidity + dew points

[harsh matrix]

I need to heavily invest in cable management

Figure out something that works remotely

[undone sedge]

usually if you restrict it to like, 180 degrees it's fine

[harsh matrix]

Thats what im thinking

[undone sedge]

can't do more than that on my scopes anyway because of my gigantic efw

[harsh matrix]

Dont need to go more than that for any reason

[undone sedge]

could also fix this by mounting my power box on the handle under my minipc but ehhh

this lets my cable management be cleaner, so i'll cope

(...and rotators are just a QOL improvement in general)

[undone sedge]

yea. the wanderer empire application makes setting the mechanical zero position & setting a rotation limit (from the zero position) pretty easy

it'll usually convert rotations if they're outside your range too

[tall summit]

@digital nexus congrats witha new scope!

[digital nexus]

thank you

[undone sedge]

if you want it i have the M54 one that i probably wont use because my SV070T has a wonky reducer

[harsh matrix]

Hell yeah

[harsh matrix]

[undone sedge]

the main reason i got it is because the moonlite is awful with rotating but i'm replacing it anyway

so that's a non-issue now

[harsh matrix]

I need M56

😭

Also how would I use that with a reducer?

I have limited back space

Back focus

[undone sedge]

i think the next biggest is M68

so you can probably get an adapter

[frosty shard]

Man why couldn't GSO focusers have M54 threads

[harsh matrix]

Yeah id have to get an adapter, that's fine

[undone sedge]

i'd personally do rotator -> reducer -> camera train
that's what im gonna do with my 102s but with the native flattener

that way it won't add to the backfocus

it'll just shift your focus position by like, 10ish mm

[harsh matrix]

Ah but I have camera <- AFW <- OAG < - reducer and I am 0.5 mm too far out of back focus as is with no way to collapse it down further

If the rotator consumes any back focus, I cant use a reducer

[undone sedge]

yea i'd do
camera <- AFW <- OAG <- reducer <- rotator

no backfocus added

[harsh matrix]

I have about 40 mm of back focus to work with

Reducer is too long to thread onto the rotator

[undone sedge]

oh does the reducer like

go into the focuser?

[harsh matrix]

Yes

[undone sedge]

bruh

[harsh matrix]

I wont be able to reach focus otherwise

[undone sedge]

hate that, my sv70t is the same way

[harsh matrix]

Because of the decoupler

It barely reached focus with the reducer threaded onto the focuser before I decoupled everything

I was reaching focus with the focuser like 5 mm out

Max

[undone sedge]

damn

[harsh matrix]

It's extremely tight with this reducer.

Maybe I could get a 0.8x reducer/flattener?

[undone sedge]

yeah i wont be able to reduce with the rotator on my 102s
not bc of focus distance, but since the threads are so gargantuan

[harsh matrix]

Since I dont need as much speed under those skies?

[undone sedge]

yea maybe

[harsh matrix]

A 0.8x reducer/flattener shouldnt consume as much back focus i dont think

[undone sedge]

i dont think it should

[harsh matrix]

Alright

Great

More things to buy probably

Im not terribly upset about that idea because the Apex-L creates vignetting that doesnt correct

It interferes with every other aspect of taking flats too

[undone sedge]

damn

[harsh matrix]

I had perfect flats and perfect stacked lights when I did RGB and SHO at native

That's about the only other factor I can blame.

[undone sedge]

yea its bascially the same feeling with my reducers, tilt is fine with my native flatteners but it's a PITA with the reducers

[frosty shard]

meanwhile, this is an actual image of me waiting for an imaging project to finish at f/8

[harsh matrix]

I eliminated my tilt

[harsh matrix]

Real

[undone sedge]

i can't be bothered to fiddle with it on my reducers tbh

[harsh matrix]

Thats why it took me >60 hours to do fish head

[undone sedge]

especially when it's perfect on my native ones

[harsh matrix]

Thats just weird

[undone sedge]

basically this but f/7 lmao

[frosty shard]

I'm all in it for the sharpness and zero chromatic aberration so it's a sacrifice I'm willing to make

[undone sedge]

agreed

[frosty shard]

especially once I venture into UV imaging

that is where refraction goes to die

[undone sedge]

my fracs quiver when they hear UV imaging

[frosty shard]

-# the glorious Ritchey–Chrétien calls

[undone sedge]

my seeing is more ass than vel's LMAO

[frosty shard]

I mean mine's not great either

but on the other hand, when it is great, I take full advantage of it

Some of my IC 10 data is utterly ridiculous

FWHMs of like 1.7"

I managed to stay at a dark site all night when the seeing said "yes."

I have not repeated that since

[harsh matrix]

Oh BTW for reference, all of my images from and prior to May of this year, back to October of last year, were shot at 0.8x reduction across both scopes.

I had to add a 25 mm spacer or so

Which if I use a rotator, and I get a 0.8x reducer, gives me about 10 mm of focuser travel assuming I thread the reducer onto it.

[digital nexus]

Do I need anything to collimate the rc6

[undone sedge]

'tis pain

[harsh matrix]

Also threading the imaging train onto something gives me more confidence than simply putting the imaging train on there purely by compression, long term specifically.

[harsh matrix]

Absolutely not

Maybe software

But no hardware

Lasers are useless

[frosty shard]

Nothing other than hex keys (I do recommend using hex keys over a hex screwdriver just for clearance around the focuser extension if you adjust the primary)

[undone sedge]

yea i think i've gotten down to like, about 1.5-1.6"
i think i've had sub-2" seeing on only 2-3 occasions

[digital nexus]

So the 3 side screws?

I wonder what hex key il need

[frosty shard]

For the secondary a hex key or screwdriver is fine, there's no clearance issues

2.5 and 3 mm for the push-pull screws I believe

[digital nexus]

I haven’t seen the back of the scope

[frosty shard]

I think 3.5 mm for the secondary, it might be 4

A little annoying you need different sizes like that

[digital nexus]

How does the hex keys work on the secondary, like do I need to loosen one side before turning another?

[harsh matrix]

Normally I feel it out

I dont try to worry about any particular methodology beyond making sure my final adjustments are all tightening.

[frosty shard]

The back of the RC6 will look similar

The adjustment screws are paired around the focuser extension

[digital nexus]

il have to be careful with how long that is. I don’t have a pier

[harsh matrix]

Oh @undone sedge I lied

[undone sedge]

https://tenor.com/view/anakin-liar-star-wars-lying-gif-8634649

[harsh matrix]

A 0.8x reducer should add about 75 mm of back focus

That is more than enough to compensate for the issue I currently have.

That will work for sure

[frosty shard]

From the DSI method document

[harsh matrix]

As long as the flattener part doesnt have to consume back focus

Thats what it looks like

Although the 6 interacted differently with reduction vs this 8

[digital nexus]

Is that for the back only…?

[harsh matrix]

[frosty shard]

Yes, the front (secondary) is just tighten/loosen, pretty straightforward

[digital nexus]

Il ask ChatGPT

to summarize the dsi method

[frosty shard]

I can do it better

[digital nexus]

The seller said he had the primary collimated and never touched it again. So I’m hoping il just need to mess with the secondary

Hopefully it’ll be good when it arrives actually

I’m doubtful though

FedEx and other shipping services aren’t known for their careful handling of scopes….

[frosty shard]

• Adjust the tilt of the primary mirror to eliminate coma - in the camera preview look at a defocused star and try to get the star to look evenly illuminated on all sides
• Once coma is eliminated, adjust the secondary mirror to eliminate off-axis astigmatism. You'll need to compare stars at different points in the field, but you want the ones on the edges to be oval and pointing towards the center
• Keep doing this until the field is nice and even

This is what nulling coma looks like

Here's what unbalanced astigmatism looks like

[digital nexus]

What software will help with this

[frosty shard]

and that's the goal with the secondary adjustments

[frosty shard]

@harsh matrix you recommend MetaGuide right?

(It's free)

[digital nexus]

That dsi doc said I had to align the top of the camera sensor?

How do I know what’s the top

[harsh matrix]

That and Sharpcap

Actually

You cant use metaguide with an OSC cam

Disregard that

[digital nexus]

fun

[harsh matrix]

Yeah Metaguide bricked my ZWO 533MC Pro drivers

[frosty shard]

Bruh what

[harsh matrix]

I thought it killed the camera for a while

[harsh matrix]

Yup

It started getting extreme banding

[digital nexus]

https://cdn.discordapp.com/attachments/1379949653990309978/1406674163841634426/37046348-D9F7-4AF1-BC35-167AEE656C19.gif

[harsh matrix]

Nothing I could do would fix it

I genuinely thought the camera died

[digital nexus]

ok so never install metaguide got it

[digital nexus]

What does sharp cap help with

[frosty shard]

capping, sharply

[digital nexus]

ok

💀

[harsh matrix]

You can view your collimation adjustments live.

Also planetary

I collimate with sharpcap primarily

Metaguide is more useful when the scope is coupled.

Oh for the RC6, if that guy got the primary nailed down, I would never touch it again tbh

You can get away with exclusively adjusting the secondary

It's much easier to do it that way as well.

[digital nexus]

thats what he said so il take his word for it

this is what he said

actually maybe this means he didnt have it collimated?

Well he did collimate it before so maybe its good... idk

[frosty shard]

GSO RCs do hold their collimation extremely well

[digital nexus]

that might be the first pro ive heard

[harsh matrix]

Lol

They also have some incredibly well figured mirrors

[digital nexus]

oh yea AI coating LMAO

[harsh matrix]

Their newt mirrors are hit and miss, often outright bad but their RC mirrors are crazy good

[harsh matrix]

I wasnt talking about the coatings

Im near certain they've been upgraded to some quartz hybrid thing now

Thats all besides the point

[digital nexus]

" Primary mirror: Hyperbolic primary mirror with enhanced Al coating to 95% reflectivity, with protective quartz layer

Secondary mirror: Hyperbolic with enhanced Al coating to 95% reflectivity; protective quartz layer; O.D. of secondary cell is 3” "

[harsh matrix]

I was talking strehl

[digital nexus]

strehl

huh

[harsh matrix]

Bruh

[digital nexus]

oh thats an actual word not a typo

damn

[harsh matrix]

Yup

The Strehl ratio defines how close to optically perfect a mirror is

1.00 being perfect and 0 being the absolute worst

GSO RC mirrors have a minimum strehl of 0.9

@frosty shard and I have mirrors with strehls that are likely much higher than that

[frosty shard]

I estimate 1/10 wave or less RMS error

at least on-axis

tested through visual inspection of aberrations with a high powered eyepiece

[digital nexus]

Have you used your RC for visual?

[harsh matrix]

Briefly

It gave me the sharpest view of the moon i have ever seen

[digital nexus]

lunar gonna be sick

[harsh matrix]

Duuuuude

[digital nexus]

i heard contrast is poor cause the obstruction, did you notice that>?

[frosty shard]

It's a hit to contrast in planetary viewing, but not to the point I'd consider it bad at all

[frosty shard]

For DSOs, wide fields, and large exit pupils, the CO is way less relevant

[harsh matrix]

My RC6 did this

[digital nexus]

im gonna put my 2x barlow and planetary cam in and see what i get lol

[harsh matrix]

Do it

[frosty shard]

Deconvolution will restore much of your resolution

[harsh matrix]

It is going to be a banger

[digital nexus]

I never done a serious attempt at Lunar

this will be great

I dont need guiding right?

[frosty shard]

Nope

[harsh matrix]

Nah not for planetary

[digital nexus]

good good

thats what i thought but had to be sure

[harsh matrix]

All you have to do is keep an eye on drift and make sure it doesnt move out of your fov

[digital nexus]

DSOs are going to be hit or miss until i figure out how im going to guide. Glad I can do planetary

How does collimation affect lunar/planets

[frosty shard]

I used my RC extensively for exploring Virgo and Coma Berenices for galaxy season, and it goes so hard

[frosty shard]

Funny you ask this

[digital nexus]

the ragdoll gonna be sick for visual. I hated using my dob cause i had no idea how to find stuff 💀

[frosty shard]

So one of the reasons why RCs have a bad reputation with collimation is that you need to check off-axis stars for astigmatism. The reason you have to do this is because if you null out coma across the field, you also null astigmatism in the center

That is actually a good thing for planetary

Because as long as it looks reasonably collimated, it is

(This is not true for the moon just because it's much larger of course)

But for small targets like planets (and perhaps even planetary nebulae) you actually don't have to worry very much

[frosty shard]

I am very interested to know how it works for visual, since I got my Wave 150i in part because it has visual users in mind

If the Ragdoll checks out for visual I'll definitely get one as a secondary mount in the future

[digital nexus]

The ragdoll has an alt az mode

I want to use Go-To, so im not sure how im going to do that accurately.

my current thought is to temporarily have my 533 in the scope,. plate solve in NINA and use that for Go-To

i dont want to find stuff lol

[frosty shard]

I only ever use EQ mode for visual

[digital nexus]

it seems to be a pain changing from EQ to ALT AZ mode so im prob not going to

[frosty shard]

and actually I was testing this out with another member of the local astronomy club who hooked up his guide scope to NINA and used it to plate solve across the sky

It works really well

The only reason I don't do this is because I keep my visual configuration very simple and lightweight

fast setup/takedown so I can catch a bus home lmao

[digital nexus]

oh crap

yea i could use the guide scope/cam

thats genius

Itll be a bit awkard if im doing it with the RC but it could work

[frosty shard]

also don't just take our word for RCs being good for visual, ask the 1000+ people who have looked through my scope lol

[digital nexus]

ok to be fair though

95% of those people dont know the basics of astro

its easy to impress people lol

[frosty shard]

That is true, I'm just here to make as many people into RC enjoyers as I possibly can

[digital nexus]

This has been my most successful lunar image

So as you see, I haven’t done it in a while

[frosty shard]

Oh buddy. You're gonna knock your socks off with the RC6

[digital nexus]

Wanna guess what i used to take that?

frankly its impressive for what i used lol

[frosty shard]

Did you use a phone camera

[digital nexus]

yep phone

[frosty shard]

Actually pretty good

Was this with the Askar?

[digital nexus]

no no no

the askar is pretty decent for lunar

[digital nexus]

I used 25x70 binos with my phone cam held up to it LOL

[frosty shard]

Actually even more impressive

Tbh I'll never stop doing smartphone astrophotography just because it's a fun challenge

[digital nexus]

This is actually probably my best lunar

this was Askar and DSLR

ignore compression

id have used my 533 but i didnt own it when the eclipse happened

[frosty shard]

Though humble, this is my favorite smartphone capture

That's M82 and its massive H-II region is actually visible in the image

[digital nexus]

that is impressive

[frosty shard]

I was not expecting my phone to pick that up

with a 5" SCT as well

I mean visually my 5" SCT is pretty good but the RC8 blows it out of the water

[digital nexus]

Im not sure if il prefer my 6" dob or RC6 for visual

Probably the RC6 simply because the dob has a crappy helical focuser and only one vixen dovetail

[undone sedge]

heh

[digital nexus]

RC6 + 2x Barlow + sv305 pro.

Gonna be one hell of a lunar FOV.

[undone sedge]

28” cdk is cheating tho

[frosty shard]

Ohh yeah that's definitely cheating lmao

[digital nexus]

RC + 533

Literally perfect

[frosty shard]

Now I want to get an adapter and try to take a smartphone image of the Orion Nebula with the RC

[frosty shard]

Unfortunately with the 8" I'm limited in field with a 533

[digital nexus]

thats some crazy detail though

[frosty shard]

And I'm limited by having a mono cam

[digital nexus]

ew

[frosty shard]

The problem isn't even having a mono cam! It's that most software for stacking sucks and doesn't have a nice way of handling mono image registration

I need to write my own software to do it

I have 16 GB of lunar frames sitting here doing nothing

[digital nexus]

so at this point, im probably limited by seeing?

[frosty shard]

Yup, lucky imaging is the way here

[digital nexus]

is seeing something i actually have to worry about now? omg

huge milestone

the RC also makes my astro spending a total of $5,000 now

[frosty shard]

Have you built a mosaic in SIRIL before btw?

[digital nexus]

no

Ive only tried a mosaic once, m31, and my mount killed itself

those subs are gone too

never even opened them up

Gone with my mini pc

along with 10 hours of my m31 project

:/

[frosty shard]

What happened

Power surge or something?

[digital nexus]

I was setting up to get some more M31 data

i was all done setting up

tried to turn on my mini pc

nothing happened

it just died

[digital nexus]

in theory i can recover the data

its just a hassle since i dont have any extra headers and itll be a pain to power it

i got a new mini pc though

[vapid patio]

@harsh matrix figured it out it was in the synscan software a a altitude limit so i just saw it in nina ascom error

anyways

[harsh matrix]

ah

@undone sedge i may just not shoot reduced

this guy on instagram, astroyyc, is shooting with an RC8 from there

unreduced

he's getting incredible results

[vapid patio]

work in progress only 1hr ha, 1hr each channel

gonna really commit to m31

[vapid patio]

looked at his atrbin

i would say you are better

[harsh matrix]

i am highly doubtful

[undone sedge]

yea tbh there’s a certain point of low lp that shooting native can be just as good as shooting reduced in the city

i worry about doing f/7 from my b6/7 house but idk if i’ll ever image from my house again after what happened back in august

i just don’t trust the suburbs nowadays

[frosty shard]

Redid the denoising with my own TGVDenoise implementation

[bleak solar]

Finally it is working 😭😭

[high aspen]

rct

[bleak solar]

What does that mean? 😅

[quartz meadow]

Ritchey Chretien Telescope

[bleak solar]

… oh

Yeah I should have guessed 😅😂

[harsh matrix]

Okay I know why

I asked him about what he thinks about his experience

He said the one thing is is disappointed with is how long it is taking the staff to learn the ropes, regarding collimation.

Their methods have been pretty slow and inaccurate, but improved since Spring of this year.

Basically, theyre not great at collimating them RC's

But theyre getting better

Most likely his images are collimation limited and he has been unable to take full advantage of the seeing

Like me he dialed in his collimation to the point of perfection

And the staff doesnt quite do that

[vapid patio]

Ah ok makes since his m16 was rc6 level so I was a little confused

Staff?

Like he has his on a dark sky sight thing

[harsh matrix]

His RC8 is at Starfront

Did you miss that?

[harsh matrix]

@undone sedge like me, this astroyyc guy on IG found out that a rotator isnt going to work when using a reducer

He also imaged with a reducer from home but found he couldn't make one work with a rotator

Instead he opted to shoot at native, which the dark skies there allows the tradeoff to be worth it.

He said the data on a new moon at f/8 is very much worth it.

[harsh matrix]

I could definitely make Starfront work right now, actually.

I just need to be more disciplined with how I spend my time and money.

And not be financially irresponsible

(Tbf all purchases, both necessary and unnecessary have already been made)

I havent bought a new piece of gear in a while, only a mini PC

I need an actual sleep schedule too so im not as tired

Actually it would probably be a good thing for me to do because it will force me to get my act together

[high aspen]

real

[sinful sapphire]

even the german craigslist is sending me notifications to buy the RC8

[harsh matrix]

Guys

Guys

My rig will work on a lite pier at starfront

I can afford it

[high aspen]

you need get it then, smh

[high aspen]

why would you go starfront?

[harsh matrix]

Because I don't have frequent access to dark skies

And I can afford a lite pier there

I cant afford any other site.

[high aspen]

oof

[tight lodge]

I didn't know Kleinanzeigen is considered as creepy as Craigslist

[digital nexus]

How much pain will I have with the rc6 out of 10

So far I’m thinking a 7

[high aspen]

5

[harsh matrix]

$600 for a wanderer astro flat panel

rotator is $400

power box is $300

looking at spending another $1300 before tax

i dont know how much tax will be and where to buy these so i dont get tariffed

[high aspen]

astroflation+usflation in one doesnt sound fun

[high aspen]

are you already having regrets 😭

[harsh matrix]

more like a 6

light leaks make the scope more annoying to use than any of the quirks of the scope itself

[digital nexus]

damn how do I know if il have that issue

[harsh matrix]

Its almost a guarantee

Light leaks around the drawtube of the focuser

[digital nexus]

and how can I prevent it

[harsh matrix]

Basically every focuser ever has a gap around the draw tube

[harsh matrix]

Either do what Cuiv did and plug it up with tape or make a more elegant thing like i did

[digital nexus]

what’s your elegant thing

[harsh matrix]

I made a little fabric cuff to go around the drawtube to stop any light reflecting up through the gap

I dont think it is flawless and it needs some work to be there 100%

[digital nexus]

Do you have a video on how cuiv does it

I’m gonna be afraid of where I can tape, don’t wanna mess up focuser

[harsh matrix]

nope

[digital nexus]

found it

https://www.youtube.com/watch?v=5ogIaGn67bQ

Stuck at a bus stop instead of doing outreach

(it's game day so the buses are packed)

[high aspen]

oh god

[high aspen]

yello reflectiv jaket :3

i wonder how a ceramic secondary holder would be

like yea, easier to break

but the less thermal expansion

[digital nexus]

What rig do you have in there

So for the RC6, how long will my imaging train be? How many adapters am I gonna need?

I’m still confused on the backfocus stuff

[high aspen]

you should have enough adapters

[digital nexus]

I’m not worried about that; I’m wondering how many il need

Because I’d rather not have a really long imaging train.

[high aspen]

i think its 1 to 2

[digital nexus]

I don’t have a pier so a collision could happen

[high aspen]

i risk collisions too :/

which is one of the big reasons i want a moar compact guy

-# other than it looking cute

[high aspen]

1 big 1 smol

im guessing

[digital nexus]

this will be fun

Jupiter is actually huge damn

[frosty shard]

My only rig, the RC8

[digital nexus]

What mount

[high aspen]

yea

rct unredoosed

[digital nexus]

I’m being told I shouldn’t use my sv305 pro and 2x Barlow

It’s too much?

[high aspen]

woaw

[high aspen]

imo, do whatever you want

[digital nexus]

The max Barlow i should use is 1.5x I guess. But with my 533 I can use 2x

[high aspen]

i think the main issue is probably reduced levels of light

[high aspen]

yeasoundaboutright

smoller pixels and that

you would need a biig picjel sensor to barlow moew

i want a chonky pixel sensor

like a 9um

or something

[digital nexus]

Yes that

[high aspen]

longer exposure = more blur

[tight lodge]

I can answer that for him. He has the SkyWatcher WAVE 150i

[harsh matrix]

an exercise in futility

[digital nexus]

I call this the Christmas Tree Light Nebula

[frosty shard]

Also update, I did end up doing outreach until I got clouded out with a totally clear forecast

I also gave someone material for a journalism class project

It might end up being a story in the campus newspaper

[sinful sapphire]

It’s the closest comparison I got

[high aspen]

ir cont subbed onion

it looks evil

[vapid patio]

How much?

[vapid patio]

I HAVE A RC6 ITS LIGHT WORK

No light leaks

Little to no tilt

Ez collinate

And you can get ccdt67 reducer

I have all stock focused

[vapid patio]

But I never had any

[digital nexus]

Why don’t I believe you 🙁

[vapid patio]

Even ask veloren

He’s been through it all with me

I was super scared to collimate then it was like oh this is easy

@digital nexus

This was early this year I have a different camera now

For this I had every single sub had star trails bc I sucked

But man it still came out great

[digital nexus]

What cam and how are you guiding

[vapid patio]

This was asi533mc pro

And I had a oag with a baddd sensor a asi120mm

[digital nexus]

Was that with a reducer?

[crisp flower]

As Long as u dont get a laser to rely on its quite okay
I tried with one and i couldnt get it to Work properly for the life of me
I have an eyepiece now and do it with it and the dsi Methode,its fairly simple

[high aspen]

@frosty shard should i get a 9um pixel sensor for the sillies

[digital nexus]

I’m not worried about Collimation mostly

I’m worried about light leaks, the coupled primary mirror, and guiding lol

[vapid patio]

No

[crisp flower]

Ooop my bad

[digital nexus]

Well I’m kinda worried abt it

But more abt the other stuff

[crisp flower]

Did u buy it already?

[digital nexus]

yes

he’s shipping it on Monday

[crisp flower]

Id wait Till u have it and then you will see what Problems U Encounter
But dont make youself too crazy with thinking about them already

[digital nexus]

I’m still confused on this dsi method tbh

I need a video lol

[crisp flower]

Its pretty confusing at First
Ive Not found any Videos about that Method so far, otherwhise it would be Here in this channel

[vapid patio]

Couples if I remember right causes astigmatism? It’s only if you have a super heavy back

[digital nexus]

So you use the camera, defocus. Just like a star test

[vapid patio]

And I have a asi585mm pro 7x filter wheel “full” btw and a oag and I’m chilling

Never had a light leak

Yep all of it

[digital nexus]

which rc6 do you have

[vapid patio]

Astro tech

Which one did you buy

I mean they are all kinda gso rebrands so same same

Unless you go carbon

[digital nexus]

White GSO

Ugly ugly ugly

[vapid patio]

Oh perfect

So pretty much the same scope “mine is also white”

[digital nexus]

I need someway to make it not ugly

Black vinyl maybe?

[vapid patio]

I have a lot of changes but this is my last photo

Btw don’t ever get a carbon fiber tripod

Like ever

[digital nexus]

uhhhhhhhhhh

Too late

[vapid patio]

At least the zwo one

[digital nexus]

I bought the zwo one

[vapid patio]

Gulp

What sensor do you have

[digital nexus]

533

[vapid patio]

Oh nvm

[digital nexus]

what

[vapid patio]

Since it’s carbon fiber it has more flex and it causes isolations. Me and veloren tried it. It’s just your guiding will have long drifts let’s say from .40-1.00

But you are wide enough you will be fine

585 sensor is small

[digital nexus]

I heard adding counterweights or actually any weights into the bag helps

[vapid patio]

Yeah dude that with a 20 pound counter weight

[digital nexus]

I never had to with my gti

[vapid patio]

Oh sick I have gti too

I like to flex my guiding with gti

[digital nexus]

I had a gti

[digital nexus]

I averaged 0.5”

sorry

[high aspen]

when i get my rc we all gonna be matching

[harsh matrix]

you dont live in an area with light pollution that is all that bad

i am willing to be that with the moon out, you have problems in broadband

[vapid patio]

Ohhhhhhh yeah yeah yeah your right

[vapid patio]

Real

[digital nexus]

@harsh matrix So the RC6 comes with the GSO Focuser, and that TS optics focuser. Will the additional GSO focuser tilt plate work with the TS optics one?

[high aspen]

amma get a carbonfiber one >:3

[harsh matrix]

Yes

[harsh matrix]

yeah, i dont even have neighbors with lights on all night and the leak is bad enough, when uncontained, that i get useless data

that's how much light comes out of the sky even when it is perfectly clear

my neighborhood is actually beginning to replace old lamp bulbs with bulbs that have little hats that aim the light down at the ground

that surprised me

unfortunately they alone cannot reduce my light pollution by enough to be noticeable right now

[digital nexus]

What bortle are you?

[harsh matrix]

8

[digital nexus]

ouch

I’m a high 5… wonder how bad it’ll be for me

[high aspen]

im mid 5

[digital nexus]

Should I spray paint the rc6

[silver ibex]

No, paint makes it heavier smh

[frosty shard]

You're sacrificing too much resolution IMO

[digital nexus]

I can’t tell if that’s a joke or not

😭

[bleak solar]

when i use my rc6 in the cold what do i need to keep in mind?
Tomorrow I can finally use it for the first time

[frosty shard]

I would vinyl wrap it tbh

[digital nexus]

That needs a heat gun right?

Id go crazy if I left a wrinkle lol

[frosty shard]

It does...but at least it's reversible

[digital nexus]

Hair dryer work?

[high aspen]

what fl would make it optimal? (with an unreduced rc6 it predicted to be okay)

[silver ibex]

I mean, it's a joke but it's also true lol

[frosty shard]

I haven't done it myself...it looks like you can do it in a pinch with a hair dryer but for best results you do want a proper heat gun

[frosty shard]

I mean it's more about f/ratio than focal length, but I'd prefer to have something like 5 or 6 um pixels

[high aspen]

ah

[frosty shard]

You could of course drizzle to get the resolution back

[silver ibex]

I'm fairly certain that drizzling decreases SNR, specifically drizzle-n implies n^2 less SNR. I could be wrong.

It definitely depends on the drizzle method and parameters too

[high aspen]

truew

[high aspen]

drizzle reduces snr yes

but that would just make it in line with the 5-6um pixels snr

flip

[silver ibex]

1cm pixels?

😭

[high aspen]

i have a 1cm pixel

i have a ldr

big pixel sensor fr

gonna do astro like a radioscope

[frosty shard]

Color transform of my Heart Nebula data

Debating whether to start getting S-II data or continue with the H-alpha and O-III

The only issue is that battery capacity is now a limitation

[high aspen]

pibk

[high aspen]

Hbeta

get geem

[frosty shard]

I don't have an H-beta filter

[high aspen]

do you at least have g filter

[frosty shard]

I do but I don't want to shoot broadband from home

[high aspen]

ah

get si

[frosty shard]

I actually was thinking though, the Statue of Liberty and NGC 3603 are both fantastic targets for H-alpha/H-beta

Because they have very different levels of dust extinction despite being next to each other in the sky

[high aspen]

arent hbeta and halpha same structure?

[frosty shard]

(NGC 3603 is like 3x farther)

[frosty shard]

Yup but NGC 3603 is reddened by dust

[high aspen]

ah

[frosty shard]

It would be very evident in that nebula pair

[high aspen]

isee

thse peopes sell good cheap filters

i like them

[frosty shard]

Anyone got a target in mind for the nebula comp?

[high aspen]

use a 5x barlow and image an emission neb in a diff galaxy

[frosty shard]

Unironically one of my ideas

[tight lodge]

NGC206 in RGB HOO

[high aspen]

great minds think alike

[frosty shard]

There's some great nebulae in that region

[alpine flame]

hi fellow RC enjoyers

i have a questionm

im planning a purchase of a 16" RC soon

and i have a big question

how do u collimate an RC? i have catseye for my newt but theres no way i can use that on a RC right?

[frosty shard]

holy crap

[frosty shard]

1. DSI method.
2. DSI method.
3. DSI method.
4. DSI method
   I could keep going

Do not even bother with a laser or Cheshire unless it's way out of whack

They do not give you the precision needed to get proper collimation

[alpine flame]

exactly

EXACTLY

no way im going for a laser

i had it for a bit on my newt and it was terrible

[harsh matrix]

@tight lodge did you say gemini flat panel?

who said gemini?

this doesnt look like it has a hinge

[frosty shard]

Collimating on a star is always the way to go. You might lose some imaging time but it's a worthy sacrifice

[alpine flame]

is there a method, im not sure how do you determine secondary and primary error

[frosty shard]

http://www.deepskyinstruments.com/truerc/docs/DSI_Collimation_Procedure_Ver_1.0.pdf

[alpine flame]

this seems complicated as shit

i need to read it a few more times

[frosty shard]

tl;dr:

1. Null coma across the field by adjusting the primary mirror tilt
2. Balance astigmatism across the field (not just in the center) by adjusting the secondary mirror tilt
3. Repeat until the procedure converges on collimation

[alpine flame]

well the procedure itself isnt that bad

i just feel like

i wont be able to spot the tiny star errors

[frosty shard]

If you get it soon: I recommend using Mirfak as your collimation star, because it's surrounded by its cluster and you can survey the whole field

If you're using NINA the aberration inspector comes in handy

[digital nexus]

bruh ive read it 3 times and im confused too lol

16” RC tho? Do you have an observatory?

[alpine flame]

no

maybe soon

we will see

[digital nexus]

What r u putting it on

[alpine flame]

i can carry it its fine

[alpine flame]

CQ350

[digital nexus]

How much does it weigh

[alpine flame]

which im aslo gonna have to get

[alpine flame]

uhhh

wait

[alpine flame]

36KG

i can fit that somehow

[digital nexus]

Isn’t the payload capacity of ur mount 35kgs

[alpine flame]

thats for photography

visual is 40

i have fit many

[digital nexus]

oh so ur doing visual?

[alpine flame]

many

scopes

[digital nexus]

ok

[alpine flame]

over the weight limit

on my EQ6

its gonna work

or im gonna get a GSO one but idk

it is lighter by a few kg but

im worried about the quality

we will see

i still have to think this through soon

[digital nexus]

Aren’t all RCs basically gso rebrands

Idk for the big ones actually

[frosty shard]

Not the big ones but any that are smaller than about 12" are GSO

[alpine flame]

I've posted many messages about the scope my club has that I've spent about 3 years trying to get working. I'm in Wisconsin and the cold weather seems to have contracted the screws locking the primary mirror and screwed up the collimation that I finally think I fixed last summer. Finally, a clear night tonight so I hoped to make a small adjustment to the primary and try some imaging.

Nope. The mirror is a mess again and I've tried the DSI Method again, but no matter what I try I've never been able to get that to work. I make sure the camera is oriented with the scope properly so I tighten the bright side of the star, but once I center it again I see no change.

Our club president suggested at a recent board meeting maybe we should get a different scope. I thought I had it figured out and said I want to give it another chance, but after tonight I'm ready to get rid of this thing. I've spent 3 years, probably well over 100 hours, Takahashi scope, Glatter laser, software, a new focuser....etc. and this thing still kicks me.

I had plans of being well into doing online public outreach, let kids control the scope through the internet, and a lot of interactive things online and in person. I've gotten nowhere with my ideas thanks to the collimating pain.

this is what a guy wrote about the GSO one

which makes me question it a lot

[frosty shard]

Do you know where in Wisconsin? (I live in Madison...)

I may offer to help this user out

[alpine flame]

its a blog from 2022

but i will drop the link hold on

Thanks

I may swing by Door County someday since it's a really good dark sky area

[alpine flame]

i wish i had proper dark skies here

[harsh matrix]

im boutta send my RC8 to Starfront

[digital nexus]

I wonder how cold it got for the screws to contract damn

[harsh matrix]

sick of bortle 8

[alpine flame]

must have been really really cold

[alpine flame]

i have heard people that regret that

idk for me it would be a dealbreaker

[digital nexus]

soo note to self. Don’t use the rc when it’s negative outside ok

[alpine flame]

cause its just not it

its cool and all u have clean data

but

its taken on the other side of the world

[digital nexus]

sending your scope away doesn’t seem like the same experience

yea you get data, but not the experience

Not the process of setting up

[alpine flame]

i would miss the option to say that THIS image was taken from my backyard

[digital nexus]

yep

[frosty shard]

I do dream of having a 16" RC someday, and I debate whether I'd want to send it somewhere remote and get the best astrophotographic data possible, or setting it up permanently at home and being the coolest neighbor ever

[alpine flame]

home.

[frosty shard]

Especially since I'd want to do visual with it (and share that with people)

[alpine flame]

i think im gonna get this one

https://www.firstlightoptics.com/stellalyra-telescopes/stellalyra-16-f8-lightweight-m-lrc-ritchey-chrtien-carbon-truss-telescope-ota.html

[frosty shard]

there is a better option: get two

[alpine flame]

but the price damn😭

i mean

buy once cry once

[digital nexus]

2 RC8s vs 1 RC16

[frosty shard]

I'll always want to have an RC8 in my arsenal, it's such a good all-rounder

[harsh matrix]

I live not too far away from Starfront

i can drive it there and drop it off

im like 5 or 6 hours away tops

[alpine flame]

id personally not go below 10"

[harsh matrix]

i can pre manage the cables and stuff too

[alpine flame]

not that bad

or just send a seestar there😭

[frosty shard]

For the decoupling issues? My rationale for picking an 8" is just that it's grab and go enough that I can take it out for outreach where I live

[alpine flame]

seriously

no offense)

but what dumbass would send a seestar to starfront

the sensor is gonna destroy the data

[alpine flame]

i like big scopes

more options ald photons

[frosty shard]

I mean I wouldn't want it to be my only scope, just my portable all-rounder even if I have a big chungus observatory scope

[alpine flame]

hell yeah

honestly if ur b8 i get it

im b4 and im getting sick of it

i want darker skies

[harsh matrix]

Yeah

brother

[alpine flame]

i guess im too greedy

[harsh matrix]

I shot 31 hours of broadband on M33

from my club's bortle 3 site

it obliterates any and all data i could ever get from home

[frosty shard]

I genuinely have thought of traveling around the world and bringing my RC around to do visual outreach

[harsh matrix]

and I got that quality of data much faster than had I done it at home

[alpine flame]

valid

i mean you gather data fast here

in B4

im just worried

its not enough for IFN

and dust

i got this in 2hrs

its not perfect data but it works

it was like 60% moon too

[high aspen]

i think if i ever get a big scope ill have to hand make it

[alpine flame]

but im just not sure

if its enough for the faint stuff

[frosty shard]

45 minutes in B7 (left) vs. 6 minutes in B4 (right)

[high aspen]

buh

[alpine flame]

okay Damn

that is huge

starfront is B1 no?

[high aspen]

if i make some good mirrors i think i would genuinely have to give some mirrors to people for less than the manufacturers offer (shipping cost + the amount in materials)

[harsh matrix]

infinitely better than me

[harsh matrix]

yes

i will shoot at native

so i will get bortle 1 speed with full RC8 capability

[high aspen]

😰

[harsh matrix]

my telescope will be unleashed there

it is so limited here it isnt even funny

[high aspen]

its all fun and games until the star front seeing becomes diabolical for the next 4 years

[harsh matrix]

nah

[frosty shard]

I think even with bad seeing I'd rather be at a B1 site

[harsh matrix]

my seeing has been stable for the last 3 years

i have the same seeing as they do

[high aspen]

climate change gunna shift the currents

[harsh matrix]

it will be the same year over year

[harsh matrix]

even if that was the cast, i could get a 0.8x reducer and manage, but id rather not

[high aspen]

im directly under the strongest part of the jet stream (above the uk), idk how i actually get good seeing

[digital nexus]

do you guys have any tips for me to quickly move my mini pc, 533, and filter drawer from my Askar 71f to RC6, and vice versa?

[alpine flame]

man i wish

europe sucks

we get like 1,5-3" seeing here

sometimes better

but this is average

cause jet streams

[high aspen]

give everything a shoe and screw loads of holders for everythig onto each scope for hotswappability

[harsh matrix]

our's goes up to 3" or 3.5" on the worst of nights

I never saw above 4" until I went to that bortle 3 site

that isnt even in the same state as me

[high aspen]

mines averaged at 3.5 for the last few days

[digital nexus]

what dew heater should I get for the rc6

[high aspen]

i somehow managed to get 2.2 one night

idk how

[harsh matrix]

im looking into that rn

[alpine flame]

preferably

none

[harsh matrix]

but for mine

[digital nexus]

How do you guys know what your seeing is, how do you know it’s 3 or whatever

[harsh matrix]

i can update you once ive found something

i got a few suggestions to go off of

[high aspen]

i use my fwhm, theres probs a better way

[digital nexus]

I was recommended this https://www.amazon.com/Dew-Heater-Strip-Telescopes-Instruments/dp/B0FD8ZYMBK/ref=ast_sto_dp_puis

For primary mirror

He uses it on his RC8

[high aspen]

i only have issues with the secondary

[alpine flame]

i saw one guy with this, i go tthe version for the newt and im very happyhttps://www.teleskop-express.de/en/telescope-accessories-5/dewcaps-and-heater-90/altair-secondary-mirror-heater-for-8-10-ritchey-chrtien-telescopes-7326

[harsh matrix]

shouldnt need one for the primary

[high aspen]

also, i think my mirrors stickiness is gonna start effecting my images soon

[harsh matrix]

i just got recommended this lol

i need to find a vendor that sells it in the US though

[alpine flame]

well its a good idea

[harsh matrix]

aint no way im buying from europe again

[alpine flame]

altair sells it

isnt it a us

[high aspen]

europe is just cool like that

[alpine flame]

company

[harsh matrix]

im pretty sure they are european

[alpine flame]

yeah they are

UK

[harsh matrix]

yeah

[digital nexus]

I messaged the RC6 seller about some stuff.

He said no light leaks ever, no Collimation issue when going to a new altitude.

He did mention some diffraction spike issues due to the way GSO held the primary mirror? It left some black areas on the outer edge of the mirror?

[alpine flame]

you can mask that

[digital nexus]

yea he includes a mask for it

I wonder how bad it is tho that he felt the need for a mask

[alpine flame]

masks are pretty normal on beveled mirrors

[harsh matrix]

bottom part is normal

[digital nexus]

He said he last collimated it August, and it’s been packaged ever since. Sooo I hope I don’t have to lol

He replaced it with an RC8 so I guess this RC6 didn’t give him a huge issue to stay away from RCs

[harsh matrix]

this is about the worst it gets

this drives some people crazy but i dont even notice it ngl

[digital nexus]

what’s it look like corrected

[harsh matrix]

my quattro doesnt have anything like this and it actually annoys me

[digital nexus]

just the 4 main spikes?

[harsh matrix]

yes

[alpine flame]

do u have it masked

[harsh matrix]

well it should just be 4 spikes

[alpine flame]

im a quattro owner too

mine is a bit

modified tho

lol

[digital nexus]

I don’t think it’ll bother me too much, but since i have the mask il just use it

[harsh matrix]

you may have some flaring if your filters are dirty etc.

[harsh matrix]

yes

the quattro is way too controlled for my tastes

it's actually boring

[alpine flame]

which one u got

[alpine flame]

how dare u

[harsh matrix]

my RC vs my Quattro

the stars have no character with the quattro

😭

[alpine flame]

do u have thicc vanes?

[harsh matrix]

very

theyre flocked

[alpine flame]

which spider u got

[alpine flame]

well thats the reason

[harsh matrix]

backyard universe

[alpine flame]

why they look like that

[alpine flame]

w

same here

which quattro u got

[harsh matrix]

my quatt is heavily modded too

150P

[alpine flame]

i got the 250P

[harsh matrix]

the only thing that is stock on it is the tube itself lol

and the mirrors

i guess

and the primary springs

[alpine flame]

exactly lol

[harsh matrix]

i dont believe he changed the cell either

but uh

after i got the collimation perfect, it hasnt slipped, even slightly

[alpine flame]

Wait lemme show it to u

[harsh matrix]

[alpine flame]

looks like this rn

i wish i had pics of the inside

its insanely dark from the flocking

[alpine flame]

its cause of the spider

the spider holds collimation SO well

its unbeliavable

i think i collimated like 2 months ago, and it still holds very well even though i keep moving the scope

@harsh matrix can u modify a RC in a way u would modify a newt or no?

maybe flocking it?

[digital nexus]

should I have gotten a Quattro instead

[harsh matrix]

the road to perfecting the quattro is not one for the weak

a GSO RC works out of the box by comparison

[harsh matrix]

it comes with knife edge baffles

[harsh matrix]

not really

not without doing some irreversible damage to things like the primary holding cell

I drilled through it to modify mine

[high aspen]

altair has their own store front which is cools

[alpine flame]

Great!

I wouldnt have the balls to do that

[harsh matrix]

https://telescopes.net/kendrick-gso-rc-telescope-secondary-mirror-heater-fits-shroud-diameter-3.html

[harsh matrix]

i was sick of oval stars when collimation and tracking were perfect

frustration will drive you to accomplish anything you wish

[high aspen]

it looks like a nosecap

[harsh matrix]

That one requires soldering with the thing already installed

I dont think I'm going to get that

Deep Sky Dad sells a pretty rudimentary one but it should still do the trick.

[high aspen]

buh

[harsh matrix]

Also I get that people keep bringing up the "but you wont be getting the data from your backyard anymore" thing but seriously

I already am not much enjoying imaging from home.

I almost burnt out in August because of it.

For one.

For two, I have another rig.

Im still going to be suffering, but with faster rigs that dont get as negatively impacted as the RC.

Plus, I have almost no access to targets between M31 declination and Horsehead's declination

Here at home, because we have a giant tree that nobody wants to take care of that has eaten up most of my sky.

That means I get almost no access to the galaxies and galaxy clusters I would like to shoot.

Starfront is a way for me to better utilize the RC in the way which I bought it for.

It is crippled here, and it feels bad.

[tight lodge]

Yes😅

[harsh matrix]

there is not a motorized version for a scope my size

[tight lodge]

What's the diameter of your tube?

[harsh matrix]

203 minimum

probably about 240 mm

[tight lodge]

203mm is the diameter of your primary mirror. Most likely the diameter of your tube is 230mm in which case, they do sell flat pannels of that size

[harsh matrix]

they do of that size yes but they dont have a motorized one

unless it isnt available on the sites i looked at
