Description

The pic was done with the same equipment (4" refractor, and Herschel wedge) of AR2042 25 April, to underline changes in the active region.

Main difference was seeing, very good on 26 April ("rice grains" were visible clearly in the RAW and even in the best frames): this allowed to stack the best 40% of 2600 and minimal PP
