Solar observation

Very short, to steal time actually. Seeing is 2-3/10, transparency is 5/10.

Two large AR comes out, namely 865 which is closer to centre, and 866 which is closer to the edge.

Ranger is used, no full disc shot captured for the lack of time. Since large AR are available, I used a 2x barlows to capture some AVIs at more than the theoretical limit of the SM40.

Attached is a 865, stacked with around 800 frames as a test first.. more coming.
