Abell 31, a planetary nebula

Also known as Sharpless 290, this object is a large but faint planetary nebula, estimated to be about 2000 light years distant.

This image is a combination of data captured using Antlia narrowband Hα and Oiii filters and Optolong RGB filters for the stars. I used a William Optics FLT110 telescope and QHY163M camera. Post-processing was carried out in PixInsight.
