Here are two consecutive days of the Sun taken with the ZWO Seestar S50. Shows the Sun's rotation (axis approx 45 degrees sloping up from left to right) as well some evolution in the shape of the sunspots. Movement towards upper-left is from Day 1 to Day 2 (22/23 December 2023).
Much fun !!!

| Sun Rotation as Shown by Sunspots |
Scaling off the image and applying some simple calculations indicates the time it would take the left-most sunspot pair about 25 days to complete one rotation. Pretty close to official information.
It would be easy to get hooked by these things - or am I talking about past tense...
