Description

Image from early 2022 taken from my backyard in Phoenix with a C9.25 with an f6.3 reducer through an ASI294MC Pro.

Just went back to reprocess it with a much improved knowledge of Pixinsight.

The image is cropped to 2400 x 2400 pixel^2.

Part of getting ready from some long focal length imaging with a C8 which replaced the C9.25.

I added a monochrome version of the image to show more clearly the stars and structure within the nebula.

The red arrow indicates the neutron star / pulsar PSR 0531 + 21 which formed after the supernova creating M1. The pulsar oscillates at about 30Hz, so with 30 sec exposures we just see an average. For information see:
