Here are two more images taken with the one-meter telescope. Seeing was quite good on the night these images were taken, down around the arc-second level (for you non-astronomers, that’s enviably steady air, that leads to tiny, sharp stars and lots of details in the images).
This is the Crab Nebula, a remnant of a supernova explosion. This is what happens when really big stars go ‘boom’ when they collapse from their own gravity. The Crab was imaged in hydrogen-alpha light, a very red wavelength emitted by hydrogen atoms. The image is a stack of eleven 5-minute images.
Here is another image from the same night, of galaxy M81 (faint fuzzy #81 in the list of ‘not comets’ made by 18th-century comet hunter Charles Messier). The camera wasn’t wide enough to capture the whole galaxy, but there are lots of fascinating details visible. This is three 3-minute images taken in visible light.
