Another backyard imaging in the big city - Sunspots

Hi,

This is test of my brand new ASI678MC camera with 2um pixel. Today (28/10/2022) was a cloudy day with around 2h of partly cloudless sky.  It seems like the pixel is just perfect for the 102ED F/11 lens, no Barlow at all!

The #3131 Sunspot has area around 450 mln km2 that is 3x the area of cross-section of the earth! 

Here is, how the sunspot looks (i hope they keep data of the old sunspot forever): https://www.spaceweatherlive.com/en/solar-activity/sunspot-regions.html#3131
