Description

A very faint Pn which is stronger in Ha than OIII, although a small amount of OIII shows in the center. Abell 1 barely registers in the red filter with nothing in the green and blue channels. This planetary lies close to NGC 7822, better known as Ced 214 and Sh2-171. Not a mind blowing object but another ticked off my Abell list.

The NBRGB combination version. It's not worth adding the Ha and OIII manually
