OBJECT DESCRIPTION AND IMAGE SESSION

 

Abell 13 is a relative large but quite dim planetary nebula in the constellation of Orion. It has an outer ring that stands out from it internal structure. It has an oval shape. The reddish color is quite noticeable and contrasts the dusty background environment.

The Abell catalog was published in 1966 by American educator George O. Abell and was composed by 86 entries of Planetary Nebulae collected by Robert George Harrington and Rudolph Mincowski

I stared imaging this object one year ago from a Bortle 4 skies focusing on the LRGB channels. The Ha integration was done from my home backyard in Bortle 8 skies in December 2022.
