This was First Light for my Celestron C6 with its new Starizona HyperStar system.
It is 20 minutes of data, on a night of a nearly full moon with many high level clouds. You could barely make out the Big Dipper naked eye. I need to do some tweaking to get the cable routing better to reduce the diffraction patterns, but not a bad first outing.
