Description

We return to our preferred targets, this time with a faint, not often imaged and documented :

Abell 66 a faint Planetary Nebula
Abell 66 (PK019-23.1) is a very rarely imaged planetary nebula about 1,800 light years away in Sagittarius. Abell66 is a medium sized Abell, measuring 4.5 arc minutes and has a magnitude listed at 14.9. It shows just barely on the RGB image. Both Ha and Oiii make a good contribution, the Oiii strong in the center of its circular form, and the Ha forming a strong outer ring. A central blue star can just be made out, but somewhat overlapped by a similar small white star.
It is estimated to be 2.2 light years across.

The image is in HOORGB in order to reinforce the signal.
