20.05.2021 Early solar imaging.

 *

Thursday 20th 51F, bright, cloudy and breezy form the west. Large plates of cloud between smaller ones.

10.39 Seeing slightly sharper than yesterday when the cloud clears. My first, presentable image. 912x912 and cropped.

I usually use 800x600. The latter rather limits frame size and resolution when cropped. Usually resulting in a digital enlargement being required to get a decent sized picture for the blog. The larger frame slows capture rate to about 94FPS. I'm hoping to use the 2.6x GPC with the larger frame for the same scale as 800x600.

11.01 52F even more cloud! Seeing improving in the short gaps of clear sun. Pushing ImPPG much harder than usual. It seems to tolerate a lot more sharpening when the seeing is better. Far more than  I ever dared to try before. 

I tried the 2x Barlow but it was far too much for the seeing conditions.

Swallows keep looking in, doing an orbit and leaving via the observation slit.

12.16. Last image for a while. 

Heavy cloud is making it pointless to continue.

Ellerman bombs or micro-flares are visible all around the AR. [Active Region]
