I checked the GONG this morning and saw some interesting prom activity. Seeing was better than average so I decided to brave the pollen for a quick observing & imaging session. I used a Lunt LS50 DS with a ZWO ASI178MM camera to capture 1,000 frames and stacked the best 25% in AS!3. Additional processing in ImPPG and Photoshop.
