Spent a couple of hours tonight experimenting some more with the QHY5L-II and saturn. I had a bit more luck working with the 2x powermate, but images seem blurry and noisy.. I'm not exactly sure what I'm going wrong. It is difficult to focus at that focal length, so I'll definitely need a mask or something to help out with that.
I also played around a bit at native focal length with similar results as last time. I sort of wish I had a color cam to try out and see what I could do.
I did discover a bug with FireCapture 2.3 Beta 10 where the long exposures (greater than 1sec) seem to just loop at the same number. I posted to the group to report the issue. I star hopped from Saturn over to M51 (through the C14), syncing along the way, to try a longer exposure with the camera, but could only successfully do 1sec. I was able to barely see M51 at 1sec (no structure or anything, just enough to know that it was on the chip), so it should be interesting to see what happens when I can run 30 or 60 seconds.
