[terse ginkgo]

Needs access

[onyx flicker]

There u go

[terse ginkgo]

cheers

[terse ginkgo]

Slightly missed focus no?

[onyx flicker]

Focus should be good there’s def some trailing because i haven’t gotten my autoguider to work

[terse ginkgo]

this doesnt look like good focus tbh

its soft. Slightly missed

do you have bahtinov mask? Or how did you focus?

also its weird because one side looks better than the other.

[onyx flicker]

Yeah I use a bahtinov mask

[onyx flicker]

I mean it’s possible it’s the filter or something idk what else it would be

[terse ginkgo]

how was the camera rotated?

horizontally or vertically?

[onyx flicker]

Horizontally

When pointed at the target it was prob 45degrees or something tho

[terse ginkgo]

Okay, so then it could be cheap focuser. And that the weight of the camera is causing it to tilt slightly

[onyx flicker]

It’s not cheap tho it’s possible it was tightened all the way I keep it a little loose

[onyx flicker]

Rotator also could’ve been a little loose

[terse ginkgo]

Anyways here you go pretty decent results with a 400-500 dollar scope.
However I would recommend you to have a look at those stars, something seems off to me.

[onyx flicker]

Yeah thx I’ll def be looking into it

[onyx flicker]

That’s most likely from the narrowband filter slightly changed the back focus and just kept it will def be looking into it

[terse ginkgo]

nope

its tilt

and a bad one

[onyx flicker]

Yeah idk then only thing I could think is it’s the camera I modded it myself maybe I didn’t align the sensor back exactly which I really hope not

[terse ginkgo]

Its not the sensor. And its not backfocus. Backfocus would make stars look like this

My guess is that its the focuser itself.

but I dont have any experience with this.

[onyx flicker]

The focused is kinda apart of the telescope don’t think I can really change it

[terse ginkgo]

So look into it, ask in #🤓-ask-a-nerd on what to do with tilt. And provide these images.

[onyx flicker]

I tried to see if anything could possibly tilt the only thing I could get is the adapter to the camera

Everything else just moved the entire scope

[onyx flicker]

Also what tool did u use for the camera tilt analysis I’ll see if i can rule out some stuff using older images and stuff

[terse ginkgo]

in siril, Image information - abberation inspector

and for the tilt

this command tilt [clear] in the command line

or just tilt works

[onyx flicker]

Ok

[onyx flicker]

So I ran that command but nothing happened

[terse ginkgo]

need to platesolve the image first

[onyx flicker]

Ok

[onyx flicker]

Can you do another tilt analysis on another image of mine I can figure out how to platesolve I’ll send the link in a sec

Nvm got it

[flint kraken]

Blurx will work nicely on this

[onyx flicker]

Yeah it does I used it for the original

[flint kraken]

good soup

I would definitely recommend figuring out the tilt

[onyx flicker]

Yeah idk what going on with that I did a tilt analysis on multiple other pics and it’s just all over the place even when it’s facing the same way and rotates the same way

[zenith oak]

its def the focus

you can see that the neb is out of focus

[terse ginkgo]

Theres multiple issues there. I know its slightly out of focus, he also has a bad tilt on that data.

[zenith oak]

prob the issue of his camera. I think the sensor might not have been placed back properly when it was modded

[terse ginkgo]

Maybe, but idk tbh. He later checked other images he got, and the tilt differed. Wasnt constant at all.

[zenith oak]

thats weird

[terse ginkgo]

I still think it could be issue with the focuser tube.

Like shifting or something from the weight of the dslr

[zenith oak]

yes could be

[onyx flicker]

I think I fixed the tilt problem it prob was the rotator it wasn’t on right

[onyx flicker]

The focus was prob because the focuser tightening nob was loose
