Thanks for posting this challenging project Bojan, it got me outdoors again.
I’m a little late to the game, but I managed to grab a session on Sunday night to attempt recording the companion of Procyon. Previously, I had easily split Sirius A & B but with Procyon I did not even get close.
I grabbed a few AVI’s at 1024x768 at various exposure settings, along with a full res 1936x1096 field at 10 secs to record the wider view.
I couldn’t record any stellar diffraction rings with the Mewlon 210 which was highly unusual, probably due to poor seeing.
I have also included an earlier image of Sirius A & B taken in 2018 with the same optical set up, but using a Canon 5D Mk IV as the camera.
After this one Procyon attempt, I feel it is unlikely that I will be able to image Procyon B, even with the star at a greater altitude and under good seeing conditions.
I have annotated the wider composite view with field stars that showed up consistently in the 3 x 10 sec exposures. I used the “Ruler Tool” in PS CC to measure the pixel separation from Procyon A and then multiplied those values by 0.15 to obtain an approx. separation in Arc Secs. However, I could not correlate my field stars with those listed in the database (green text top left) at the following link.

Unfortunately, I did not note the orientation of the ASI 290 MM during the capture….
