Description

Sun Spots - 20221108

I also captured these sunspot yesterday (20221107) because weather changes often and intensely here in the Alps: The sky was constantly covered by high thin clouds (cirrus) with not a single second of blue sky during the day. Nevertheless I tried it because I wanted to capture these sunspots with beautiful penumbras. Yesterdays image result came out much better than expected because the seeing was good despite the clouds.

Today the sky was much clearer though still many cirrus clouds passed my field of view. From 1000 frames shot with FireCapture on Astroberry I stacked 50 (5%) for this result. I enhanced contrast significantly to make the active regions near the Sun disk's border more prominent.

Version B is the 'normal' version ... without the contrast enhancement.
