Basic astronomy and night sky information
The Sun kicked it into high gear this week! A few big prominences emerged, especially a towering tornado-shaped construct on the southern solar limb. I just managed to catch the tail-end of it this morning as the Sun cleared the trees at my observing location. Took a few images of the prom, went for a cup of coffee, came back to the telescope, and – POOF! – it was gone. South is up in this image, captured with a Lunt 60MT H-alpha solar telescope and Player One Apollo-M Mini camera.

A recent thread on the astronomy forum Cloudy Nights explored the possibility of capturing quick ‘snapshot’ astrophotos with small but sensitive monochrome cameras and inexpensive, small-aperture lenses of less than 25mm (!) aperture. Even better, this approach used no astronomy mount or tracking at all, just a fixed camera tripod and a PC to capture and stack each image over the course of a minute or two. Lightweight, cheap, simple.
It seemed like a preposterous idea. So of course I had to try it!
