Trying to decide not to get an OAG. Still... Must satisfy my curiosity and try one. Almost there. Evidently, there is star elongation in these images but I find it hard to find.  Of 37 or so light frames for each, I lost just 4 to bad star trailing. Can't be too bad I try to tell myself...

So here we are. Still with the f8 and with everything as tight as it should be -I think-. Cassiopeia still, imaging each night about 2 hours up to the meridian, trying desperately to remember to stop about 10 minutes before the flip so avoiding the telescope tube crashing into the mount.
