Details:
Large sunspot 3363 is getting close to rotating off the face of the sun. But, holy cow....the wildfire smoke was back with a vengeance (from western Canada over 2,000 miles away!). See the visible satellite picture. Yuck! Exposures were doubled and gain was much higher. 127mm f/9.4 refractor, Quark-C/Lunt tilt-tune double-stack filter, ASI174mm camera.
