Uploaded 7/11/24

 

            
Sharpless 2-36 is a
            bit of a rare bird, it is an isolated molecular cloud in Ophiuchus
            that Sharpless included in his compilation. With no nearby star
            to illuminate it fully, this object is dimly lit by near by stars
            near the core of our galaxy, and thus appears mostly yellowish
            in hue. Note the nice spiral galaxy on the left below the beautiful
            orange star - 12th magnitude NGC6070.
