Sirius A and Sirius B

This is my first successful capture of Sirius B, the faint companion star of Sirius A, the brightest star in the Earth's sky.
Using a red filter, to slightly help with atmospheric seeing, combined with 3-D printed vanes to deliberately cause diffraction, thus reducing the encircled energy around the very bright A-star, redistributing that energy into diffraction spikes in the background.
