Abell 49 is a rarely imaged planetary nebula in Scutum. This is the first image on Astrobin, and I found only 1 very small color image on the web. Abell49 is quite small, measuring only 0.5 arc minutes and has a magnitude of 16.2. There is no hint of it on the RGB image, but both Ha and Oiii show it easily with Oiii about 20% stronger than Ha. This is everything I could find on the web about this PN. Very obscure.
