Description

Comet C/2013 R1 (Lovejoy) with a superb ion tail

The processing entailed a Kappa-sigma stacking method of comet isolation using a group of images taken on the evening of 5th December before comet-set and a larger group of images taken after comet-rise early on 6th December. Star isolation used a modified Hubl method to remove the blurred comet artefact using a star aligned median stacking.

The linear ion-tail features were enhanced using a radial blurred difference-offset mask and "overlay" blending in photoshop
