I always naively thought you couldn't see M31 from Oz but PeterK set me straight, cheers Pete. Ever since I've grabbed 5 mins here and there (because of my observing position) in osc. The other week I decided I'd better setup where I intended putting the obs and actually check the views :screwy: Managed a few hours of mono instead of a few minutes between trees. I thought I'd already posted this but xelasnave prompted me and after giving it a quick process himself gave me some ideas, cheers Alex! Given the contribution of Ha I don't know whether it was worth so much time but it's all learning to me :)

Yours is beautiful and makes my attempt look like putting lipstick on a bull.
Well done.

A fine result, and I'm sure that getting hours of data was far more satisfying than a few minutes here 'n' there. :thumbsup:

Great looking images John. How much time does M31 spend above the horizon at your location? It doesn’t get much above 14° here in the ACT - stays really low - and is visible for only a few short hours.

Mate, you're way to modest. It was your great effort that inspired me to try harder - thank you! I still think yours has a lot better detail, core notwithstanding ;p



Thanks Warren, the first time I saw it, between the trees, took my breath away. I knew I had to move the rig someplace better but I am learning and keeping the rig within hobbling distance was necessary. Finally I was confident enough to leave the rig unattended.



Thanks Dave.



Cheers Alex. That was 4 hours, 8:30-12:30 and by that time we were at about 10° and the star count was a lead balloon. The highest it got was about 22°.

Yes I am too modest that's for sure ..my humility is just part of me so there is little I can do..

I tried to work on the core but things did not go as I wanted unfortunately and all of a sudden I got bored and went off to play guitar...

But your subs are really first class..I look at your subs then look at mine and I feel I should give the game away...your dedication to details has me wondering if such an approach actually has merit.

So what else have you got?

Great image.
I tried it last Saturday on a dark site and while I could see it on the screen, the wind was that bad that I had to throw out many subs.

Thanks Alex, you are far too kind. I'm a "first principles" learner generally, get the fundamentals right and the rest will follow, in theory anyway :lol: I'd rather throw away a night or two than try and "fix" it in post.

I might have a Triangulum somewhere. I really need to store/sort my data by target then date rather than the other way around. Your expression/question reminds me of the "Ya'll got an more of them pixels" meme :lol:



Thanks Wilsil, what a shame. I can only off the advice I was given: short exp at least give you less overall time culled. I almost always do 30s for this exact reason. Granted stacking can be a bit of a chore, relatively. Also, high(er) gain and short subs get reasonable results in less than perfect conditions, check out my high gain experiments for example, they were done in very poor seeing.
Looking forward to your result ;)

Nice work, John. I can't see Andromeda from my usual locations, so hat's off to you for capturing it.

Cheers,
V
