Diagonal noise streaking

@raywuk This kind of noise is known as walking noise. It unfortunately is impossible to get rid of during post-processing and the only way to prevent it is to apply dithering while taking images.

Many thanks, another step up the learning curve.

This is my image (screen shot) after integration and applying crop, remove light pollution, calibrate background and calibrate star colours. For my first ever astro image I'm pleased with the result but if anyone has any guidance to further improve it id be most grateful .

@raywuk Very nice but I would expect more color in M31.

Yes, that's what i thought, but the question is how?

Any pointers appreciated.

Like i said earlier this is my first attempt at Astrophotography so its all a very steep learning curve.

@raywuk I took the screenshot that you posted here and opened it in an image viewer and played with the color saturation. That gave me this:

That was done with little effort to do it well so if you take the time for it then you can increase the color saturation of the galaxy without making the background too colorful.
