Yesterday morning (25/5) was hard work to say the least. This is a 2k x 2k crop of the more interesting quadrant, taken with the Altair Wave 125, Hypercam 26M and Altair 3nm CaK filter, armed with a 1.6 Barlow to create a 4kx4k full disc with a square ROI.

No speed up with that ROI - just removes the vignetted corners you get with a 1.25" filter and aps-c sensor. I set the scope overall to f/19.5, so had sub-critical sampling at 393.4nm.
I was experimenting with the Sharpcap Pro tracking and seeing tools. I used the seeing filtering which kept about 1/4 of the 120s runs at 14FPS in MONO8, so typically kept about 400 or so good-ish frames to send to Autostakkert, then stacked the best 7 (also tried 15,30, 60 - 7 was best).
