The clouds decided to really play hard ball this morning. We set up with wide open blue sky and thought we had time for a full imaging session and started with white light 540nm images. Not paying particular attention to the sky we suddenly saw clouds pass through the capture image on the screen. Don't those clouds move quickly when they want to. Damn, no Ha images for today. The white light images were stacked with AS!3 and sharpened with ImPPG.
