Description

Imaged on nights of 8/25/2020, 8/26/2020, 9/2/2020, 9/15/2020, 10/8/2020.

Abell 46 is an almost never imaged planetary nebula. This is only the second posting on Astrobin, and I could find no other color images on the web.

It has a very prominent central star of magnitude 14.9. Both Ha and Oiii are fairly strong, so this is not a difficult target.

The central star of Abell 46 has been found to be an eclipsing binary with an orbital period of 11h19m. It is 1 of only 2 planetary nebulae that share this rare trait, the other being the nucleus of Abell 63.
