Diagonal noise streaking
Hi, this is my first attempt at APP and indeed my first go at Astrophotography.
Ive used APP to stack my 52x120secs images using all the 'automatic' defaults up to integration but when i zoom in on the integration image there is a pronounced diagonal noise streaking on the image.
(not sure if its showing up on this screen shot)
The 52 lights were taken with a Canon 600D DLSR on a RedCat51.
Like i say, this is all completely new to me so any advise will be much appreciated.
Forgot to mention i only had 10 Darks(120sec), Flats, and Bias frames.
@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.
