Description

I bought a narrowband green filter to make my white light solar photography a little more interesting. This is sunspot #3433 from 2023-09-15 at ~15.00Z.
The mouseover is with the filter. Notice how the granulations are more prominent and the penumbral filaments less so. The umbra is about the size of the Earth.

The last two versions use the Mike Cranfield / Bill Blanshan Solar Toolbox. [2024-03-06]
