Abell 31 or Sharpless Catalogue SH2-290 is a very large and dim planetary Nebula in Cancer. Very hard to capture on my Skywatcher 200P 8 inch F5 Newtonian telescope with the 6nm Astrodon Ha filter
7.5 hours of exposure time over 3 nights has hardly scratched the surface, but a very rewarding and seldom imaged target in the night sky.
Unfortunately poor seeing and poor telescope tracking has conspired to make this a rather soft image, but I will come back for more next season.
