Messier 1 (M 1) - Crab Nebula

Introduction | Map | Sketch | My Own Observations | References

On this page I collect my observations of the galactic emission nebula M 1 in the constellation Taurus / Bull.

 

Introduction

Taurus / Bull is another constellation that I only knew by its name. Thanks to the Hyades (Mel 25), it has now become somewhat more familiar to me - at least its star Aldebaran, which glares conspicuously yellow (or golden). While the Hyades are at the center of Taurus, the galactic emission nebula M 1 (NGC 1952), also known as Crab Nebula, is located at its left end and slightly above the end star zeta Tauri.

My Own Observations

Observations February 2017

The galactic emission nebula M 1 (NGC 1952) received a "three-star rating". Unfortunately, this does not affect the fact that I was not able find it at first (binoculars, Heritage 100P). But maybe I was looking for M 1 at the wrong location, and it was not the nebula itself that was too weak to be seen. Using my GSD 680 8" Dobsonian the next day, I was also not able to find M 1. And the same accounts for the Heritage 100P on the GoTo mount: There was nothing to see! I therefore assume that light pollution here is too strong to be able to recognize M 1.

On February 18, however, I looked for M 1 again using the GSD 680, and this time I was able to recognize, at least, a weak glimmer with this scope - and this was reproducible! The same applies more or less to the Heritage P130 on the GoTo mount (Feb, 26, new moon).
