Sirius with the Elusive Sirius B

I learned in my EarthSky newsletter about Sirius B being at 11 arc seconds of separation from Sirius, giving us the best chance to observe or photograph it in 50 years. I took about 250 1/2-second photos to try to overcome bad seeing, a killer with an image like this. Then I manually weeded out 25 I thought were good enough to stack.

I used Blur Xterminator in PixInsight to help sharpen and correct the stars, but not much else.
