Description

Sh2-216, the second closest planetary nebula to earth. It is BIG, not quite fitting in my FoV, but too faint to realistically consider doing a mosaic unless you have very frequent clear skies.

I imaged this over several months due to the bad weather and avoiding brightly moonlit nights, ultimately acquiring 33 hours of 1200s exposures with the ALP-T dual filter.  Rendered in a HOO PIP palette to highlight the areas of mixed Ha and Oiii.
