Fast newts, coma, small chips
Hi all
I'm looking at going to a fast newt for imaging, I guess I'm happy with the focal length of my ED80, not happy with the aperture.... I'll probably get a 8" f/4 newt....
I'll probably give it a try without a coma corrector to begin with, as I'm getting an Atik-420, which has a reasonably small chip - should I cough for a Baader now, or does anyone think she'll be right with the small chip???
Is anyone imaging on small chips, fast newt, sans coma corrector???
