Description

This animation compares two stacked images: 20x 2-sec iso100 exposures, and 6x 5-sec iso800 exposures. The first series attempts to detect and split Sirius relatively faint companion, while the second series has a more standard processing and provides some stellar context.

It is center crop, covering 10.2 x 6.7 arc. minutes. Sirius A and B are approximately 9 arc seconds appart. The little bump at one o'clock of Sirius glare, is at the exact position predicted for the Pup.
