Welcome to my astronomy blog, I dedicate myself to the simplest form of amateur astronomy which requires only portable equipment. I have two small refractors, two small binoculars, one small GOTO mount and another small equatorial mount, and a small H-alpha solar filter. Originally from a city where the people were proud of their light pollution, that is Hong Kong where I loved. Relocated to the UK since 2021.

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.
