Description

Testing the ASI178MM. All images acquired through SharpCap 3.2 as FireCapture did not work to full speed with the new camera (yet). Poor seeing by the time I managed to do the close-up and the CaK. Surprisingly the active zone does not have an official AR number (maybe it's an old one that's rotated fully?).

Full disc is mosaic of two halves - 15% of 5000 frames at 54fps, FL 1030mm

Close-up is 15% of 10000 frames at 220fps, FL 1580mm

Cak is mosaic of two halves - 20% of 3000 frames at 54fps, FL 658mm
