Annotated Horsehead

PixInsight has tools that "plate solve" an image and allow you to annotate it.

 

Script/Image Analysis/Image Solver

and

Script/Render/Annotate Image.

 

A variety of options are given for catalogues and named stars/objects/constellations. Right Ascension and Declination coordinates and gridlines are given.

 

I knew that the Horsehead dark nebula is Barnard 33 but I had forgotten that is also Sharpless 2-277!
