Messier 78 (M 78)

On this page I collect my observations of the galactic recflection nebula M 78 in the Orion constellation.

 

Introduction

The galactic reflection nebula M 78 in the constellation Orion constellation is not on my "Winter list" (it has only a "one star" rating...), but because it seemed easy to find to me, I looked out for it, as well.

February 2017 ... December 2019

Well, all search seemed to be in vain - I did find M 78 neither with binoculars nor with the small 100P Dobsonian telescope (4") - not even with GoTo mount. With the larger 8 " Dobsonian GSD 680 telescope I might have caught a glimpse of M 78 and another nebulous object, but I would not want to denote this as "find"... But finally, on February 26 (new moon), I indeed found a weak glimpse of M 78 with my Heritage P130 5" Dobsonian telescope on my GoTo mount (and thus, conclude that I had seen it with the GSD 680 as well). And only in December 2019, I saw M 78 well for the first time with my new C8, and was able to identify it without any doubts.

Beginning of 2020

Wit the eVscope I was able to see more details under a dark sky.

Find/Identify

Find: M 78 is located at 1/4 of the distance between the left girdle star Alnitak (you need not remember this name ...) to the left of "shoulder star" Betelgeuse and a small amount outside (or to the left...) of Orion's body.

Identify: When I see a "shimmer" with two stars in it, I know that I have found M 78 (see the sketch). (Image Courtesy of SkySafari Astronomy, www.simulationcurriculum.com)

 

Sketch

The sketch by Michael Vlasov (DeepSkyWatch.com) provides a rough impression of what I should have - and may have - observed:
