    Deep Sky Workflows

    Astrophotography for everyone: images, videos, and articles about space, nebulae, galaxies, planets, telescopes, and how to take and process deep space images from your own backyard.

    The first nebula I photographed is also the first item in the Messier Catalog. M1, also referred to as the Crab Nebula, is the remnant of a supernova estimated to have occurred less than 10,000 years ago, with the light taking around 6500 yeas to reach us. At the center sits a spinning neutron star. I decided to revisit M1 as my project for the week. This is the result of 6 hours of exposure over three nights. Processed a second time with BlurXTerminator.

    This is a detailed rendering of the crab nebula using a combination of broadband and SHO filters.

    This was a focused capture using 5-minute exposures over two nights with the Optolong L-eXtreme filter. The Crab Nebula was mistaken for a comet by astronomer Charles Messier in the late 1600s. Frustrated, he started a catalog of 'things to avoid' and the Crab was awarded Messier 1 or M1 for short. I wonder what his reaction would have been had he used an EdgeHD instead?

    The Crab in 2023

    To start the new year, I imaged the first item in the Messier catalog on the first day of the year. Coincidentally, M1 was the first deep space object and nebula I photographed. This is a stack of several nights of 5-minute exposures that sum to just over seven hours of integration time.

    M1: The Crab Nebula

    It started as a supernova recorded by Chinese astronomers in 1054 AD. M1, the Crab Nebula, is the expanding remnant of that millenia old explosion.
