Description

Having tried to capture Sirius B a few times and failed, it was nice to finally get a clear shot of it. To facilitate favorable diffraction spikes, I used a cardboard mask, as well as a blue filter. The distance between Sirius and Sirius B is about 10 arcsec, which corresponds to about 47 pixels at this scale (I counted them off to make sure). North is to the right.
