My first attempt at M31

[Earl]

This is what I have managed to get out of my image... It looks a bit pants

Revelation D80 56 images 30s 800 ISO

I guess it could be worse

The first image is pretty good. But i don't think you're getting enough data. Can you take longer subs? What F ration are you taking the subs at. Too slow and you won't get the data you need.

My morning remix..

this is not an easy thing to do

Hi Earl

I think that's very good for a first attempt - as Mark has said - longer subs would give you more data - also you could turn up the ISO on the camera (if you're using your DSLR) and try an LP filter - I've got an Astronomik CLS CCD on mine and very pleased with it.

Cheers

Dont longer subs blow out the core even more?

maybe 2 sets of subs, short for the inner then longer for the outer.

I think there is far more data in my unprocessed image than i am able to get out at present as everything is starting to bloat quiet bad.

Not at all bad is that......... try playing with the colour and also flip it vertically.

Here's a quick mid-morning effort.

maybe 2 sets of subs, short for the inner then longer for the outer.

That's exactly what I would do. Treat the core and the outer as two separate targets. You can also process areas separately in photoshop by duplicating layers and changing the levels of areas independently.

Cloudwatcher, (you may have already done this) but could you do a primer/guide on processing images.

Your skills are very high and I always struggle to bring out the best in any subs I have taken.

OOO now I am happy !!! thats really nice

If you could do a step by step tutorial that would be awesome

Here is a link to the DSS generated TIFF

I need help with processing too, I'm getting the data but I think I'm too heavy handed with levels etc. A step by step even just on one target would be amazing. I can't believe how much data you've pulled from the original, gobsmacked. And rather depressed!

I have read that many times, and it appears to miss steps out or expects prior knowledge

A much more broken down step by step guide is required.

Hi,

I had a wee go at your M31 here, I am certainly no expert, just getting going really.

Tell me what you think of this and i will explain my process. Didn't take much really.

Might of blowen out the core a bit and i think the colour balance isn't perfect but like i said i'm no expert.

[Earl]

I actually have a work in progress, which is a massive improvement on my original, im just waiting on an answer from a friend why im unable to creat new layers on the image.

I have a friend of 20 years who is quiet frankley a Photoshop God!

and of course when I get into this.... I move away from him !!!

DOH

[msinclairinork]

Sounds like a good guy to know

[Earl]

Thanks Peter !!!

I do struggle with written guides and been dyslexic does not help LOL!

[Psychobilly]

Glad you found the link useful

I just find it so much easier to watch someone do something and see the effects as they happen...
