Sunspots

I noticed some tiny sunspots today and tried imaging them using a bader white light filter. The solar disk is a single DSLR shot and the inset was done with lucky imaging.
Details
Sept. 13, 2021 from my rooftop patio at Ross Place in Victoria BC.
Solar disk was captured with a Canon Ra on an Edge 8" SCT using a Baader white light filter.
Inset used a ZWO ASI120MM-S camera with 2.5x Barlow to produce a 3,000 light frame video clip. Stacked the best 300 in Astrostakkert. Sharpened the result in Registax and used photoshop to add colour and some enhancement.
