2019 October 01 - Sirius A+B at Hokoon

Sirius has a very dim yet heavy component. The huge difference in brightness (at magnitude -1.5 and 8.5 respectively) makes resolving the 2 components very difficult.

Camera: ASI1600MM Pro, cooled to -13.5C
unbinned
cropped 800x600
Taken from 20:19:41 UTC and 20:20:41 UTC
