thanks, but as noted in my sig, it's a 294mc, not a cooled camera, and i plan to stick with non-cooled cameras.
the idea of adding a refractor to the mix has definitely been in my mind, though, and i have one that Errol recommended on my wish list at Astronomics.
btw, i can't view the diagonal link you kindly provided in either Safari or Chrome. does the link work for anyone else?
