There’s no known (to me) catalog designation, but this is a cloud of molecular dust in Ursa Major. This image is the result of about 32 hours of integration time using ~800 sub-exposures. Taken with my Takahashi Epsilon in Southwest New Mexico. #astrophotography #photography

The Northern Trifid Nebula is an HII region of active star formation about 2100 light-years away. It's surrounded by a large cloud of molecular dust known as the California Molecular Cloud. This image is the result 22 hours of exposures from my telescope in New Mexico. #astrophotography #photography

The Coma Cluster is one of the earliest indicators of dark matter. In 1933, Franz Zwicky noted the discrepancy between the galaxies' velocities and their tendency to stay together, suggesting a form of dark matter. Over 90% of the cluster is believed to be dark matter. #astrophotography #photography

The Rice Hat Nebula on the left is a verrrrry faint supernova remnant. It was hard to pull out even with my fast (f/3.3) scope in the Bortle 1'ish skies of SW New Mexico and over 34 hours of exposure time. But...here it is. #astrophotography #photography
