Lunar Imaging Session - July 11, 2014

The sky tonight is clear so I use this opportunity to test out the William Optics Megrez 90FD refractor as well as the Feather Touch 10:1 dual speed focuser on the Meade 8" f/10 SCT. Seeing is bad so I wasn't able to crank up the magnification. I tested the Megrez 90FD, a 90mm f/ 6.2 doublet ED refractor coupled with a generic field flattener and Canon EOS 500D DSLR to test on the Waxing Gibbous Moon at prime focus. Afterwards, I switch OTA and tested the Meade 8" f/10 with the Feather Touch 10:1 dual speed focuser to see if I can achieved before focusing then the original SCT focuser which is very bad with lots of backlash. I initially tested with a Canon EOS 500D DSLR at prime focus and needed 2 frames to capture the entire Moon so I mosaic the 2 images of the Moon. Afterwards, I use the ZWO ASI120MM webcam at prime focus of Meade 8" f/10 SCT and tried out the Vallis Bouvard region. I can say is I'm happy with the results despite the poor seeing and hope to do further testing in the days to come. Below is an image of the Waxing Gibbous Moon take at prime focus of William Optics Megrez 90FD refractor.
Here are the images taken using the Meade 8 f/10 SCT.
