Ok, I understand. I've also found a few galaxy images around the same focal length I'd be at.

Could you point out some specific images? I've tried searching but I seem to turn up images using an FLI 16803, not an ICX-694.
[QUOTE=RickS;1235529]The only disadvantage of the 694 is its small size which is fine for typical galaxies but not so great for large nebulae.
Theoretically, I can solve the large nebulae with mosaics, so while it's not ideal, at least it's not impossible.

What am I looking for here? What budget do I need to get something to work with the ICX-694? Even with the fully configured QSI, I'd still have some budget left if I'm going to go further into the deep end.
