Details:
Here is a solar h-alpha image from today taken with a Sol'Ex spectroheliograph connected to an 80mm f/5 refractor stopped to 70mm and an ASI178mm camera. It was 13 degrees F with a 15 mph wind (-3 degree wind-chill) while I was imaging. What was I thinking? Crap, it was cold! When is summer?
