It's interesting to hear your comment.
Cookbook CCD - been a while since I've heard that name. I started out in astronomy when they were around, late 90's. I never had the chance to buy one before webcams became popular and I got one of them instead.
I suppose the thing with the DSLR's is they produce pretty images for low cost, as compared to 'deep' images the SBIG style cameras produce. And I guess for a good looking image it doesn't matter what the limiting magnitude is as long as there's some nice detail and colour visible.

Geeday Roger,
You are correct that the DSLR can produce pretty pics for a low cost and it doesn't matter what the limiting mag. is. I suppose ideally us astrophotographers need two cameras. A filter-modified DSLR for those big clouds of nebulae, and a Monochrome CCD Camera for those distant/small galaxies.
Best Regards
Paul
