Description

Data for the LRGB image was captured by Olly Penrice on his Tec 140 at Les Granges in the Haut Alpes. Olly felt that the planetary nebula Longmore-Tritton 5 might benefit from some OIII data shot through a 3nm filter. As such, I gathered 7 hours of OIII shot through an Astrodon 3nm filter on my Esprit 120/QSI 690. This was then scaled to fit the LRGB data via Registar.

The date shown is the final date of capture.
