Crab Nebula

Crab Nebula M1, a supernova remnant in the constellation Taurus, imaged with a Sky-Watcher Equinox 100ED refractor at 628 mm focal length on a DIY reducer, an ASI533MC cooled astronomy camera, dual-band H-alpha and O-III filter, and an ASI 174MM guide camera. This photo was imaged and tracked using a Vixen GP mount with DIY go-to telescope controller.

To find the Crab Nebula, locate Auriga first and then scan the region south of Auriga, near the bright star in Taurus. A narrowband filter helps in increasing the contrast between the nebula and the sky (such as using a 12 nm OIII for visual use, or 6 nm dual-band OIII and H-alpha for photography). Due to the nebula’s small angular size, a telescope with 4 inch aperture or larger with relatively long focal length is recommended for this target.
