Hey thanks... this looks like it will really come in handy the next time I try the night sky out.

I tried some moon pictures through my Celestron C5 (5" SCT) last night, but I couldn't get the focus right. The rebel viewfinder sucks! I'm gonna look into that Angle Finder C. Kinda pricy though.

one thing the page doesn't seem to mention (but maybe i missed it) - you should put your viewfinder cap on during your exposures and darkframes because it keeps stray light from entering the camera.

Is this important during the exposure itself? I always understood this a being important while light metering etc but not for the actual exposure. Does anybody know?
(I think when the mirror comes up it blocks the way for light into the camera/sensor - but I don't know for sure)
