Jones 1 Planetary Nebula in Pegasus
with 10" f/3.9 Astrograph
Uploaded 12/1/20

 
This
            15th magnitude planetary nebula is one of the most difficult
            targets in the sky to image satisfactorily due to its very low
            surface brightness and spectral composition. At 5 arc minutes
            in size, it is only half as large as say the famous globular
            M13 in Hercules, but has a unique teal color from its high OIII
            composition. Many years of trying on this one to get a good image,
            by far this is the best Ive done. Notice the small patch of nebulosity
            just below the main disk.
