The sun had a few nice sunspots today including active looking 3435. In addition, two new emerging sunspots (3436 and 3437) looked promising. I also added a spectroheliogram in h-alpha. 127mm f/9.4 refractor, Quark-C/Lunt tilt-tune double-stack filter, ASI174mm camera. SHG image 80mm f/5 stopped to 70mm and ASI178mm camera.
