The sun was very active this may, with Aurora Borealis seen at very low latitude.
This picture is taken with a 60mm William Optics Telescope with a Chromosphere Daystar Quark Filter. The Chromosphere filter has a dial where the HAlpha wavelength can be tweaker. The visual views are impressive, but a small telescope at F/6 works best because the Daystart Filter has a 4x Barlow integrated, and is optimized for roughly a resulting focal ration of 25.
Visually, the best with this filter and this small Apo is a 25mm eyepiece, to view the entire solar disc.
This is a mosaic of 4 images made from 700 frames each. The Camera used was a ZWO ASI 432MM. Even with a relatively larger frame (17mm), combining multiple images for a complete view of the Sun is needed. This was taken on 5/10/2024 at 19h08 UTC from Concord, CA.
The large solar spot group on the bottom right is the region 3664 (Carrington Rotation 2284).
The details on region 3664 below was captured using the same settings, with a ZWO ASI 290 MM camera which has a much smaller pixel size (but also a much smaller sensor). This was taken on 5/10/2024 at 19h021 UTC from Concord, CA.
