Details:
The sun today has little sunspot activity. But too often, when imaging photogenic sunspots, I neglect nice filaments. So, today, I featured a nice filament. I also added the lonely sunspot 3486, just about to rotate off the solar limb plus a full-disk spectroheliogram. 127mm f/9.4 refractor, Quark-C/Lunt tilt-tune double-stack filter, ASI174mm camera. SHG: 80mm f/5 stopped to 70mm, Sol'EX spectroheliograph, ASI178mm camera.
