oh wait you werent supposed to know about those

Mountainous areas are horrible for seeing unless you're on the highest peak

harsh matrix
harsh matrix
#

ill go to the highest peak there

runic violet
#

Good luck with that

runic violet
#

If you want to cheat at planetary you should look towards Florida, Texas, Arizona, and socal

#

Also urban centers are great for planetary because the air can be quite still as a result of trapped heat

Look like the Canadian bacon industry's gonna keep running their smokers at full blast until Tuesday sadly

Bortle 1 skies in southern Texas justright

frosty shard
#

Best skies I've ever been in

harsh matrix
runic violet
#

You gotta have bortle 1 at 10k feet

#

That'll blow your mind

#

Only a few sites in the US like that

harsh matrix
frosty shard
#

Unfortunately I've only been up to 10K feet in the daytime

runic violet
#

Sierra Nevadas, Mt. Graham in AZ, Mauna Kea

#

Appalachians are a bit too light polluted

frosty shard
#

Oh, but when I was a kid I did get to go to Palomar Mountain

#

There was a winter camp there

#

Unfortunately I never got to see the observatories

#

But it was the first time I'd ever seen snow

runic violet

harsh matrix
undone sedge
#

its also too humid over here...

runic violet
#

Humidity is very bad for transparency

#

Can be good for seeing though

harsh matrix
#

turned my bortle 3 site into a bortle 5 site roughly

undone sedge
#

yeah
i do notice whenever I get good seeing here i get worse transparency, and vice versa
its always humid

harsh matrix
#

that was super disappointing

undone sedge
#

spring, summer, fall, and winter

#

being close to the mountains doesn't help either

runic violet
#

Clearly your conditions are telling you to do only widefield DSO and planetary imaging

undone sedge
#

thank god i'm keeping my frac reduced nowadays kekw

frosty shard
#

I'm giving my conditions the middle finger

runic violet
#

Aren't Madison summers supposed to be good

harsh matrix

#

real

harsh matrix
#

that's a fun focal length to shoot at with an APS-C

frosty shard
harsh matrix
#

i wish i had one of those but theyre so far out of my price range it's not even funny

runic violet
#

Canada moment

undone sedge
#

once i've got both i wont technically need to reduce, the speed will come with two scopes

however more speed is always appreciated, especially since i'll never see sampling down to 1"/px with my seeing and the rayleigh limit on them

runic violet
#

Svx80t and sv70s are pretty cheap

#

Svx102 is not that far from your RC and is basically the same price as a 10" RC

frosty shard
# runic violet Aren't Madison summers supposed to be good

The other issue is the very high nighttime humidity in general, so you absolutely need dew mitigation for any telescope with a forward lens. My RC hasn't dewed over internally but it's often ended up dripping wet, as has my tripod and my eyepieces

undone sedge
#

though tbh i think i get better stars with my native flattener so i might not even bother reducing when i have the second one online

runic violet
undone sedge
#

especially with easier mosaics from 2x scopes

harsh matrix
#

on my trip to the bortle 3 site with my RC8 it dewed over

#

but fortunately that was long after the night ended

#

i was honestly shocked

#

id never seen my RC's dew up before

frosty shard
runic violet
#

No shield?

frosty shard
#

*Oops sorry

#

Shield, no strip

runic violet
#

Okay good

frosty shard
#

Got that mixed up

runic violet
#

The strips are kinda pointless imo

#

Unless you are a hyperstar user

#

You're intentionally putting heat in front of the light path...

frosty shard
#

We've been out several full late spring and summer nights and the corrector has been free of dew

runic violet
#

So it can't be that bad

#

There are dewy nights where the shield is not enough

#

But those are nights where SCTs should just pack up

frosty shard
#

I remember a night in Virginia Beach where my 3" f/8 spherical Newtonian on a dinky altaz mount totally fogged up, primary and secondary mirror

runic violet
#

Yeah real humidity is living near an ocean

#

Or large body of water

frosty shard
#

Or in my case, between a massive swamp and the ocean

#

We'd also get smoked out too due to swamp fires in the summer

#

And the mosquitoes were so bad that the city would have to pull out trucks to spray neighborhoods with insecticides and repellents

runic violet
#

Worst I've gotten is Newtonian secondaries dewing in socal from the marine layer

#

That's it

#

On a 12"

#

Everything is dripping wet but the primary is too large and too protected to dew

frosty shard
#

That scope might have had some opening near the primary cell but that was back in 2011 or so

#

I don't remember

#

It was the hobby killer scope I started with

runic violet
#

I'm now in Arizona so dew is a non-issue AwkwardSmile

frosty shard
#

Unfortunately my current issue is that dew may have damaged my tripod

runic violet
#

No marine layer, always dryer then bone

runic violet
#

Was it a bird Jones or on a shitty mount

frosty shard
runic violet
#

Spherical at 76mm f/8 is actually really good

#

It's less than 1/6th wave rms

#

Probably 1/8th or so

#

Maybe poorly executed

frosty shard
#

Also 0.965" focuser and terrible Ramsden eyepieces with it

runic violet
#

That.. would do it

frosty shard
#

My next scope was a Celestar 8

#

Night and day difference

#

I still have and use the Baader Hyperions I got with it

harsh matrix
#

starting to look pretty crazy

#

just did an old fashioned HDR on the tips pillars

runic violet
#

achromats can only do narrowband at the wavelength they were nulled at without any SA

#

they can't do both Ha and OIII too well, only one or none of them

#

guidescopes are not made to be diffraction limited and usually have a crapton of SA to be unusable for imaging

#

a semi-apo doublet will do better with narrowband since the problem is minimized

#

but a triplet is more likely to have decent performance at all wavelengths

frosty shard
#

I actually got it as a super finder primarily

runic violet
#

that's an exception

#

its made to be used for imaging as well

#

its also more expensive

harsh matrix
#

much happier with this HDR though HOLY

#

it's subtle but it makes a difference

#

LOOK AT ALL THE LITTLE BOK GLOBULES HOLY

harsh matrix
#

the RGB stars i got are tiny

#

these are not blurx'd

#

after blurx with very small sharpening, the small ones become about a pixel in size

#

2.25" FWHM for the entire RGB image

#

the segment ill use is likely much smaller

#

yes the stars ill be using, aka the ones that are on axis, are 2.1" in size OMEGALULDance

#

some of the smallest stars ive ever had

harsh matrix
#

here it is guys

#

first real process of my SHO M16 data with those RGB stars

#

the first one im real happy with

#

ill sleep on it, see how i feel tomorrw, then i may post it

#

it takes a fat dump all over my attempt last year MadwithJoy

tight lodge
harsh matrix
#

i was using a bad telescope with an OSC cam i wasnt totally happy with

#

that was ultimately the limiting factor at the time

#

it's that tasty resolution im talking about though

#

that's what is significantly better

#

i have twice aperture

#

now you can blink between this year's and last year's

#

my frac had some really weird optical defects too

#

so there is some amount of image shift and the stars arent in the right place... if that makes sense.

tight lodge
#

The colors in yours from last year are a bit more saturated than mine

harsh matrix
#

it's more down to the color balance i opted for

#

also i simply just didnt have as much Sii last year

#

thanks to using an OSC cam with already bad Sii QE MadwithJoy

#

and shooting at f/7 in the same skies

proven coyote
#

Osc ewwwwww

tight lodge
#

Also, why is your OIII more transparent than mine?monkaHmm

harsh matrix
#

i tend to process with an emphasis on depth and clarity so you will see my image appear to have more depth and transparency

#

that's something i tried really hard to do

#

it could simply be down to how saturated your image is tbh

#

wait @tight lodge does your image have Sii?

harsh matrix
#

you may either not have enough Sii or you saturated the image too much

tight lodge
#

In fact, I has so little SII and OIII that I couldn't balance the channels properly. So the trick that I did was to have the outer region in Foraxx and the core in SHO

tight lodge
#

M16 is gone for me now🤣

#

Now I hope that next weekend is clear so I can get a glimpse at Helix nebula

harsh matrix
tight lodge
# harsh matrix NOOOOOOOOO

Let me tell you why I'm just skimming over these targets. They are exotic targets for me.
Usually I have a window of 2 to 3 weeks to image it, and because if my job, I can only image in the weekends.
Mostly I want to image them just to add them to my catalogue. I'm well aware they are bad because I have yo shoot them very low in the horizon and only for couple of minutes.
Once I'm done with these (Helix is the last) I will lock on a project tho

#

First is the Cygnus wall in NIR HO or NIR SH. Not decided yet.

#

Because this, really boosted my moral when it comes to IR processing

harsh matrix
#

these were the smallest stars ive gotten in memory kekw

#

it's on the verge of refuting Whooptie's claims

#

technically it kind of already does MadwithJoy

#

if i can grab a focuser that isnt balls, it can probably get sharper images more consistently

harsh matrix
#

i think i want to come back to M16 with my 533 to shoot a bit of NIR just to see what i get

#

I had really hoped to reveal a lot more structure on this thing, which i did

#

but JWST's data is a lot more tasty looking

#

i want to see if i can get those hidden stars to show themselves

tight lodge
#

Too bad I'm not verified. I have the perfect emoji for that statement kekw

But

#

Are they only real because thats what our eyes are telling us?

runic violet
#

yes

#

also what surprised me is that there's reflection in the eagle

harsh matrix
#

Thats some tasty resolution

#

My broadband stars look blocky as hell and they arent even that small compared to yours

#

Wtf 😭

#

Sitting on a mountain looking ahhh

# runic violet hehe

But how about this? Technically is narrowband, but all the channels are colorized to their real spectrum colormonkaHmm
Tis real color?

I hate it when discord is duping my messagesAstroTilted

Its like diet broadband

looks like a whole lot of Ha

SII is deep red but also very low strength

He doesnt have much Sii

tight lodge
harsh matrix
#

Im getting an H-beta filter

#

I will have to destroy it because it will be useless

runic violet
#

no you can just copy your Ha channel and paste it at 486nm

harsh matrix
runic violet
#

for visual tho

harsh matrix
harsh matrix
#

I have a 10 nm H-beta and Oiii for visual

runic violet
#

yeah i didn't bother with the 10nm h betas

harsh matrix
#

Its like cheating in bortle 3 but useless here at home

runic violet
#

do you not have a uhc

#

either way any of those three filters will be better than unfiltered in LP

harsh matrix
#

Which if I ever bother doing visual here at home I will use

runic violet
#

uhc is quite effective in dark skies

harsh matrix
#

Is it?

runic violet
#

that's kinda the point of it

harsh matrix
runic violet
#

h beta + oiii

harsh matrix
#

Oopsies AwkwardSmile

runic violet
#

you have them separated

#

if you're solely concerned about object visibility and not about structure the order of importance is 1. uhc 2. oiii 3. h beta

harsh matrix
#

I dont recall trying the UHC out there.

#

Its a huge help here at home though

runic violet
#

but that leaves out a lot of details

harsh matrix
#

I could see the Veil nebula unfiltered there

runic violet
#

a lot of h beta objects are solely h beta objects

#

oiii/uhc objects usually have something to offer in all three filters

harsh matrix
#

Well the H-beta oiii filter made Lagoon look like a live photograph in my dob

#

Blew my mind

#

Same thing with the east and west veil nebula there

runic violet
#

i.e. California nebula, Cocoon, Sadr region, any SH2 region

harsh matrix
#

I saw the crescent neb with it as well

#

It was really cool

harsh matrix
#

Wtf

runic violet
#

examples not up rn would be the horsehead, seagull, and flaming star

harsh matrix
#

Oh yeah definitely

runic violet
#

you see the most on the Veil with a uhc because the hydrogen and oxygen are separate features

#

however the oiii filter gives you the most contrast so people say its the filter for the veil, although you are sacrificing the hydrogen component

#

Lagoon likewise is brighter and more extended with a uhc but you get more contrast with a oiii

#

Crescent is far more visible by uhc than oiii

#

though again in b3 the contrast with an oiii may help

harsh matrix
#

Fudge

#

I gotta give the UHC a go out there next new moon

runic violet
#

the darker the skies the less the contrast gain with oiii

harsh matrix
#

Assuming transparency isnt too bad again

runic violet
#

oh when i say uhc i mean like a 12nm bandpass that barely transmits both h beta and oiii

#

not the super broad filters

#

those have their own niche

#

lumicon/astronomik uhc being an example

tight lodge
harsh matrix
#

Thats pretty much what I already have

runic violet
#

when you said 10nm h beta and oiii

#

that's one filter?

#

not two?

harsh matrix
runic violet
#

cause that wouldn't be 10nm

harsh matrix
#

I dont remember what band pass it is

runic violet
#

501-486 = 15nm at least lol

harsh matrix
#

I think its 20

runic violet
#

yes UHC in visual lingo means a filter that passes h beta and oiii and nothing else, with maybe the exception of Ha

#

passing Ha is irrelevant because we're insensitive to it

#

ok so you are already using a uhc

harsh matrix
#

24 nm oops

#

I couldn't remember off the top of my head

#

Its not actually explicitly specified either

runic violet
#

what is it

harsh matrix
runic violet
#

anyways this is not really a uhc, its a wideband or lp reduction filter

#

its too broad to be a uhc

harsh matrix
tight lodge
# harsh matrix

Yeah... the IMX585 can be a pain when it comes to long wavelengths IR

harsh matrix
#

That sucks lmfao

#

Get tricking into thinking you discovered a PN

#

Instead it was a quality issue with a filter OMEGALULDance

runic violet
#

but yeah people buy separate OIII only and H beta only filters

harsh matrix
#

I would have but I didnt really have the funds at the time and I just wanted something that I knew would do the job during my first trip out there.

#

It ended up paying off

#

M42 looked insane...

YO @frosty shard @vapid patio HPS said they'll be getting more stock of those focusers some time this month!

harsh matrix
#

They said if you order one now, it guarantees you get one once they arrive

If thats the case, I may put the RC8 down for the time being because the filter offset nonsense is driving me mad MadwithJoy

#

Ill place an order soon myself

#

By soon, like, later today kekw

Ok sick I might be saving up for a 571 as I relized I dug myself into a hole with getting such a small sensor

#

I cant go bigger scope without bigger sensor

harsh matrix

the 571 is a hell of a lot of fun

#

im going back to my ares for the time being though as i want to test all of my filters and the 8x1.25" EFW ive yet to use

got lots of fun gear to test in the coming weeks, and i think my quattro is near perfectly collimated rn

it wil be up to the challenge

okay order placed

i am going to eagerly and impatiently await the shipment of that hardware kekw

i cant wait to see what this scope does with an even better focuser lmao

harsh matrix
# oblique sun why

Their newtonian mirrors are proven to be worse than 1/4 wavelength with will be highly detrimental to the sharpness of your image.

harsh matrix
#

Did he swap out the focuser?

vapid patio
#

no

#

but the stock one seems fine ish compared to gso ones

#

its much stringer

#

stronger

harsh matrix
#

Its garbage

#

If that one doesnt have a linear rail on the bottom of the drawtube, its straight trash

#

Its so flimsy that the focuser gives you flexture

#

Not to a subtle degree either.

#

Literally different corners in your images depending on the side of the meridian your scope is on.

#

The version with a linear rail on the bottom of the drawtube is slightly better but still trash.

#

It wont handle a loaded mono set up

#

However, there is a saving grace to the quattro

#

The CYCK focuser is dirt cheap and built like an absolute tank

#

It is vastly superior to any other focuser you could even dream of buying for a similar price.

#

Im not speaking from what ive heard about the CYCK focuser either

Oh, by the way, how much will what my telescope is seeing move when I move the secondary mirror when collimating my RC?

vapid patio
harsh matrix
#

And never touch the middle screw

#

Leave that one be

#

The secondary movements are fortunately very subtle and easy to control

vapid patio
#

so i heard AstroTilted

harsh matrix
#

Its really easy to command to where you want it to go.

vapid patio
#

my friend with the same rc as you cant collimate it to save his life. he says he barely moves it and the star disappears

vapid patio
#

maybe he is doing the middle one lol

harsh matrix
#

Thats really bad if thats the case

#

Moving a screw on the secondary of my RC8 barely even moves the field

#

I can do a quarter of a turn and not even move a star a quarter of the way across my screen

vapid patio
#

and is there a good way to collimate without having to get a new software? or you swear sharpcap is the way to go

vapid patio
#

idk if you tried in nina and gave up

harsh matrix
#

The reasons I use sharpcap are to get immediate feedback of my movements, I can regulate how much movement I make in real time, I can reverse a movement immediately if I think I went too far, and you have reticles to use in Sharpcap

vapid patio
harsh matrix
#

The thing about collimating the secondary is you need the star you want to collimate on to be perfectly in the middle of your screen with minimal deviation from the middle before you make adjustments

#

Your initial slew can probably get you close but if you use one of the X reticles, it will show you the exact center of your optical axis.

vapid patio
#

asiair had a nice reticle and a live mode smh smh

harsh matrix
#

Then you can make any small adjustments to center your star perfectly

vapid patio
#

does this look bad bad?

#

or super easy

harsh matrix
#

When it comes time to collimate the secondary, you need to return the star to the center of the image after every adjustment as secondary adjustments must be done on axis.

while it wasnt dialed in all the way, it was WAYYYYYYYYYYYYYYY closer to being perfect this time, so two nights of very small adjustments and now my corners are perfect on my 533 wholesome

that should tell you something

@tight lodge its just easier then peering into tiny hole while trying to adjust mirrors

There was this dude, for 2 weeks straight he was like... your colimation is not good enough, do it again. So I spent 2 weeks colimating the telescope every day. Everytime I was saying... this is good enough, the guy responded with "Yeah, but not good enough. Do it again!"

@tight lodge did you need a coma corrector with your scope?

#

Just thinking like 585 sensor is so small I wonder if its a need

vapid patio
#

@frosty shard your a smart guy what do you think

frosty shard
#

Are you asking about the coma corrector bit? I have no idea with Newtonians

#

But I think the 585 should be small enough that you can get away with not having one

vapid patio
#

That's what I was thinking

harsh matrix
#

it just hit me that my RC8 has a better and flatter field than my redcat

#

😭

frosty shard
#

At least with my IMX533

harsh matrix
#

i know a dude with the carbonstar rc8 running it with a 571, unreduced, and he gets a dang near flawless field

#

here's a ready made, out of the box imaging newtonian astrograph!

#

yo they updated the marketing images for the RC8 decoupler

#

this thing actually looks like it decouples

frosty shard
harsh matrix
#

i might try to get my hands on one

harsh matrix
#

well teleskop-express

#

the issue this may have with my equipment though, is that this eats up enough backfocus that directly threading my reducer to my focuser will cause my camera to not reach focus

#

i dont know how to work around that...

frosty shard
#

Also looks like it got pushed back to December for availability

frosty shard
harsh matrix
#

YAY

#

we can ship to the US

#

from these guys

harsh matrix
#

it says expected to be available from january of this year

frosty shard
#

DD.MM.YYYY

harsh matrix
#

im dumb dumb

#

it's a relatively cheap solution to an annoying problem

#

costs half as much as Nate's custom made solution too

#

i like seeing this photo because it is a lot more reassuring

#

i was worried it would be like a copy/paste of the 10" with some not well though out choices made to retain access to the primary collimation screws

#

wait

#

they already made the instructions for installation available

#

okay yeah, going by the installation instructions, this is a bonified decoupler

#

it removes all stress placed into or on the collimation mechanism

#

ill definitely buy this and give it a try when it becomes available

#

i think any cost is worth killing this astigmatism for good

#

any cost that is below $500 AwkwardSmile

harsh matrix
#

they included an internal baffle thing too to stop stray light

#

something the stupid "collimation ring" sold for these RC's for years now didnt include

#

the connection is ACTUALLY direct

#

the focuser ACTUALLY transmits all of the weight into the primary

#

why did GSO think this was a good idea

#

actually looks premium

#

installation is pretty straight forward

#

now im excited to get my hands on one

vapid patio
#

@harsh matrix OH HELL MAH THATS A WHOLE YEAR OF MONEY FOR ME

harsh matrix
#

same here tbh

#

if i saved every cent i got for a whole year i could buy one of those

#

but life doesnt work that way now does it?

vapid patio
#

Sadly doesn’t 😔

#

@harsh matrix I think I'm gonna hold off on my 650$ quattro I could pull the trigger on right now

#

Or should I? AwkwardSmile

harsh matrix
#

you should hold off imo

#

if you find a good deal on a used RC8

#

like 800 to 900, youre already spending on a scope that fixed about 90% of the problems that quattro will have

#

if you already buy a focuser upgrade for the RC6, then that will not be an issue either

#

all you have to worry about are the coupled mirrors once all is said and done

#

the quattro is actually a laundry list of problems

#

I got my RC8 for $750

#

and the dude paid the shipping which was 110 or something 😭

#

he was okay with it for some reason

vapid patio
#

@harsh matrix you forgor camera

i know a dummy with a quattro 250p and a 585 and he gets good results when he actually tries

vapid patio

that's where im at rn

or you could get this

#

it would probably be a nightmare though

vapid patio
#

mine is i would say 900

vapid patio
harsh matrix
#

ez

#

just grow another 600 dollars on your money tree

#

i see the quattro you are looking at i believe

#

this one has the "better" of the two focusers that come on the quattros

#

another thing to look out for with this quattro is if he is including the coma corrector or not

#

if it even came with one

#

definitely dont buy the quattro @vapid patio

#

the 200P doesnt come with a coma corrector

#

so if that guy didnt buy one separately and isnt including it with the scope, you are fuqed

#

yes having a coma corrector is that important and the coma corrector is 400 dollars at a minimum

#

that's probably why it hasnt sold

#

not because of the price but because there is no mention of a coma corrector

#

the 6 inch quattro is the only one that comes with a coma corrector

#

the rest dont

#

jesus

#

this one sold but its proof you can knab one for cheap

vapid patio
#

@harsh matrix OK I READ IT ALL

#

sorry for caps

#

ok i wont

#

@harsh matrix should i go carbon?

harsh matrix
#

it's not nearly as annoying to move around as a steel tube scope

#

plus you have less weight concern for your mount

#

easier time guiding for that reason

vapid patio
harsh matrix
#

most RC8's are carbon fiber afaik

#

there arent many out there that are not

#

new prices, doesnt seem to change much there either tbh

#

but i havent actually actively looked for steel tube RC8's

#

oof this is a more complicated question than i expected

#

there are a bunch of other things that can affect the new price than just the tube

#

generally these turn up much cheaper on the used market

Turns out if you want to use an RC8 on an eqm35, you can

#

I have wondered this whole time

#

It balances well

runic violet
harsh matrix
#

I already know it can't handle an 8"

#

MY EQM35 does guide extremely well

#

But it has high frequency oscillations that make it unsuitable for imaging with long focal length scopes.

#

In RA specifically

#

The dec rarely ever needs to move

runic violet
#

Oh visual

harsh matrix
#

Yeah kekw

#

The reason I didnt buy an 8 when I first got an RC is the same reason I didnt go straight for a 10 when I bought the 8

#

I didnt/dont have an adequate mount.

harsh matrix
#

If you want an 8 to use for visual on occasion until you can get a better mount, I think its worth it

#

Especially if you have dark skies

#

Aka anything not bortle 7 and higher since below bortle 7, its not as bad imo, a CLS filter helps a ton.

oblique sun
#

well that does not apply to me

#

im b7 and higher and i dont really plan on getting a better mount anytime soon

already tested it with highpoint and yk what happened

harsh matrix

Those are normally returned for a reason and 9/10 times they are going to arrive at your door step completely fuqed

oblique sun
#

yea thats what i was thinking

#

sometimes there is a bit of luck, like i returned my tube rings cause i just didnt need them but i doubt thats very common

#

especially with a full scope

#

i just dont know what to buy tho

#

it doesnt look like agena is restocking gso anytime soon, i emailed them and they basically just said "idk man"

@harsh matrix you have a Touptek AFW right? And 1.25" filters?

harsh matrix
frosty shard
#

I'm trying to figure out if there's a better way to solve the screw hole leaks than electrical tape

harsh matrix
#

But my filters are mounted and the mounts are thick enough that they block off the holes

#

I actually didnt tape up the holes for unmounted filters on my ZWO EFW 1.25" and its fine

frosty shard
harsh matrix
frosty shard
harsh matrix
#

and while it doesnt seem like there would be light pollution from "home", it's still going to have a wild effect on your narrowband images

#

I dont know of a better way to cover those holes other than electrical tape, so if you want to put this to the test, you will have to think outside the box

frosty shard
#

Oh yeah the effect is definitely visible

#

And yeah I just find it frustrating that there isn't enough clearance on the opposite side of the filter wheel for me to just put the mounting screws in reverse

#

If there was enough clearance then solving that issue would be trivial

harsh matrix

i thought about trying that too but i dont see a way that it would work

There's a lot of color splotches that are coming from a lack of integration, so saturating that much makes those splotches pop out.
