Originally posted by totsmuyco Canon came up with a camera specifically for astrophotography. Does anyone know what's the difference between that camera and a simple DSLR like Pentax. After all, I've seen a lot of fabulous astro shots by some members here.
Both the Canon and Nikon "Astro" camera's are not about the built in Astrotracer we have in our camera's they have different filters on their sensors to capture extra light frequencies that normal sensors cut. So they are more for attaching to telescopes with equatorial mounts and computer controlled movements, to take lots of pictures for deepsky stacking.
I have rarely seen any stacked photo of the Milkyway these days, from either Canon, Nikon or Sony ect camera's, that has been as sharp as the single frame shots we get from out camera's, let alone when people start stacking our images as well.
I will say, for me, and ease, I still just use the jpeg directly from my K-1 mostly, using Darkframe Noise reduction, and am always happy with how simple it is to get great pictures, without having to bother with any PP. I think , that's something that puts a lot of people off trying Astro, but, the beauty is, With a Pentax, it's easy as. They really outdid themselves with this feature.
