Good evening all, I am very new to astro photography and I appear to be struggling. If anyone is willing to help I would really appreciate it. I live in a bortal 6 area so I purchased a IDAS LPS-D2 Light Pollution Suppression Filter for my Canon 5d MkIII. Anyway, I have been learning bits as I go along and decided while the sky was clear last night I would take some images for stacking. I have never stacked before so followed some instructions that I found online. I proceeded to take my darks, bias and images however because of the filter everything comes out green, how do i return colour to my images? I had a go at stacking the images but the final image was not much different to one of my 2m exposures. I understand I have a lot to learn and patience is going to be the key, have I done something wrong when stacking?
The below image is one of my single 2m exposures
The image below is about the best I can do, nowhere near what I was hoping for to be honest but it is my first attempt.
All advice would be appreciate,
Dave
