IC4592 in Scorpius - The Blue Horsehead Nebula
Stellarvue SV80 f/6 Astrograph
Uploaded 6/19/23

 
This
            aptly named object in Scorpius is rather huge and just fits in
            the 4 .5 degree field of my SV80. Appearing like the side view
            of a horse head, it is all reflection nebulosity both in blue
            and yellows. A rich Milkyway field is in the background.
