Nobody noticed the tape measure was on the wrong way around!
With only 4mm or so showing and the other 30mm obscured it reads
34mm That's not good!
First night out last night but only with the
smaller DSI II chip. Stars looked crisper to focus but the seeing was
bad. This CCD never shows off-axis elongated stars anyway, even working
at F5.
Hopefully by Thurs nite I should have a test shot with the QHY-8.
