Description

This GIF animation shows the Sirius system. I videoed Sirius with my ZWO ASI 1600MC, adjusting the gain and exposure time until the White Dwarf, Sirius B or the Pup became visible from time to time to the upper right of Sirius A. The video frame rate was ~ 25 fps and over 2 minutes I collected 3200 frames. Sirius B was visible in ~ 500 frames. I used VirtualDub to laboriously remove the images which did not show it. I don't know of any software to do this automatically.

Sirius B is clearly visible as a tiny point of light at about 1 o'clock. Additionally I stacked the resultant video file with Autostakkert and sharpened with RegiStax to produce an image where Sirius B shows up as a separate bluish spot in that position.
