Description

Caught a break in the clouds in the early evening and was able to grab some full disk and close-up views of the Sun showing AR 2765. Thee surface of the Sun just got a lot more interesting with some sunspots to track.

Imaged with a Lunt LS50Tha, 0.5x focal reducer, ZWO ASI290MM. Imaging train was configured to give ~F/3.5. Image capture using Firecapture (see below for exposure settings). Stacking in AutoStakkert3 (best 25% of 1000 frames). Processed in Registax (wavelet sharpening). Skipped including the prominence image since there wasn't much of interest today.

Surface image:

FPS (avg.)=80

Shutter=0.090ms

Gain=250 (41%)

Histogramm=92%
