AR2827 in High Res, Part Deux, HA & WL | June 1rst 2021

[MalVeauX]

Heya,

 

Woke up to some decent skies this morning, the temperature delta was crazy, it was getting very hot this morning, already sizzling in the upper 80's heading into the 90's in direct sunlight. Scopes were hot to touch after just a few minutes in direct light before being pointed at the sun. Had to shade everything including myself. Seeing was highly variable today, with large temperature deltas I usually get bad seeing. Despite the SSM showing dreadful seeing conditions, looking on the screen at the live feed shows rapid peaks that were quite good despite the measurements coming back poor. I imaged through it with lucky imaging and managed to get some decent frames that were sub-arc-second out of a really bad average (see my seeing chart, its bad today). AR2827 is lovely, great mottling and filaments in the area despite being smaller sunspot. Added in some photosphere of the area. Seeing was hard on short wavelength so Calcium was done at a smaller scale and finished with some full discs in near UV & Calcium.
