Description

Imaged Mare Crisium on the nights of July 13, 14, and 16, 2021.  I was interested in capturing the changes over a few nights as the illumination changed.
July 13, 2021:  9% illuminated
July 14, 2021:  16% illuminated
July 16, 2021:  35% illuminated

Imaged with a C8 Evo, ZWO ADC, Baader 685nm IR pass filter, and ZWO ASI174MM. Imaging train was configured to give ~F/20 (~0.18 arcsec/pixel). Image capture using Firecapture with gain set at 250 and an exposure of 30 ms. Stacking in AutoStakkert3 (best 25% of 1000 frames). Each of the three mosaics was generated from 2 panels using Microsoft Image Explorer. Wavelet sharpening and histogram adjustment in Registax6.
