Jupiter 12/3/15
First full stack with the QHY5L-II, fair seeing, Celestron Edge HD 925 @ about f/45.
RGB RGB RG composite and derotated in WinJUPOS, in total 4300 frames for RG610 filter, 2800 for Green filter and 2800 for blue filter. lost the final G and B sequences due to poor seeing.
Prior to the imaging session i used Metaguide / firecapture and a mag 3 star with RG610 filter for frankly easy in-focus airy disk examination in fair seeing, for collimation. I was off by about 1/32 of a turn on two screws, maybe less. The difference was so shocking i nearly fell off my chair. The sequences i pulled were far far better than even the night of good seeing back on 3rd march! Can't wait for good seeing night.
