This is a picture of Abell 21 (The Medusa Nebula). This is a planetary nebula about 1500 light years away in the constellation Gemini. This is an interesting PN due to the asymmetry in its composition. This could be because it is a very old PN. I chose this framing because the upper right corner of the image contains open cluster NGC2395
