Description

Very difficult object to image - very faint! Had some very good seeing but also very hazy skies for over half of the acquisition time so dealing with gradients was a chore.

A is OIII, B is Ha, C is BiColour using the dynamic narrowband tutorial on https://thecoldestnights.com/

The very blue star in the centre of the planetary nebula is its originator, white dwarf GD 561 (http://cdsportal.u-strasbg.fr/?target=GD%20561) which apparently is moving away from the dust shell: http://adsabs.harvard.edu/full/1994AJ....108..978T
