Finally had a clear enough night (with no wind) to go out and run the scope for a bit. After taking Dave's scope off and putting my guider back in place, things set up and came together pretty flawlessly. I've taken 10 5min Lum exposures of the Rosette while the sky was quite clear, and I'm now queued up to do some 15min HA exposures, but there appears to be some high cloud now, so we'll see how it goes. I've just got one frame from the camera so far, and the HA is absolutely amazing!
I did notice that I've got some high frequency moaning in the RA axis when moving at high speeds.. I assume it's a combination of the cold, and probably my fiddling around with the spacing of the gears when I was investigating the source of my backlash. I'll have to go out in the daytime and fix that.
