Veil Nebula 10 July 2021

The Veil Nebula, a remnant of a supernova, was my primary target for this evening. The night started out well with a clear sky and steady seeing, but after midnight, instead of the clear sky predicted for the rest of the evening, small clouds moved in rapidly. Thinking I would just let the camera keep shooting and discard frames later, I kept the observatory open.

However, the sky rapidly clouded over heavily and was followed by thunder and flashes of lightning! I went through a quick shutdown and closed up just a minute before large drops of rain started falling. See the video below. I happened to decide to leave my wide-angle camera shooting frames every 30 seconds with a view "over the shoulder" of my main scope.

The periodic white flashes lighting up the wall to the right are from the imaging DSLR shooting 4-minute frames. But at the end of the timelapse video, the entire sky lights up with lightning flashes, after which I quickly closed up the observatory.
