If anyone reading this is considering the Atik 414EX for example, galaxy work, check out this full frame sensor shot of the same object by Mr Crouch using a similar F/l scope. Knowing that my shot is not cropped, it will help you gauge just how small this sensor is. Again, no biggie for me - I have the FSQ + 6D for wide field work
