Description

Saturn with its moon Rhea at dawn on Wed 26 Apr 2023 AEST (collage version).

First light with the new ASI678MC planetary camera. It was about a time for an upgrade as I've been imagining with Skyris 236C for the past 5 years now. Spent few nights optimizing FireCapture settings and trying out various F ratio combinations. In the end F16 worked best with ADC in the train, happy with 78 fps. ASI678MC's Sony chip has 2 micron pixels which is an improvement on 2.8 micron Skyris sensor.

WinJUPOS composite of 8 drizzle stacks, just under 14K frames in total. Greater image scale helps with identification of finer features within the belts, hopefully southern hemisphere will put on a show this opposition. Taken half an hour before sunrise at 6:08 am Canberra time.
