Description

A number of clear days just before Easter in March 2021. Seeing was average and my flats could not correct fully the Newton rings from my old ASI120MM. Practice for the summer months when the Sun will be higher from earlier.

Hydrogen Alpha image taken at 1300mm is a 9 panel mosaic. The CaK image was taken later in the morning using a 0.5x focal reducer at the native 700mm focal length. Variable seeing is noticeable in the panels of the larger Ha image.
