Description

Still got a lot to learn about imaging at longer FL - very glad I started on shorter scopes initially. This is not my best, but it's a step in the right direction - seem to have finally nailed using the OAG wth PHD2, and also got my guiding calibration better (helped also by tighter PA). RMS was around 0.7" for the whole session once setlled down, and dipped under 0.5" for some periods - which means it's close to the magix 1px on the 3.75um camera I'm using. Very happy with that. The less good part is the smudgy stars - need to work on my collimation, clearly I haven't tamed the RC8 yet in that respect. Understandably, that also seems to upset Hocus Focus too, so I had to manually focus for this session.
