Description

This is data from Olly Penrice's place at Les Granges. Three nights (29-31 October 2016) on Olly's dual Takahashi 106 rig. I processed this about a year ago but was never very happy with it. I decided to have another go after attending Paddy Gilliland's excellent presentation at the International Astronomy Show in Warwickshire earlier this month.

The data consists:

L 7.5 Hrs in 20 min subs

RGB 3 Hrs per filter in 15 min subs

Ha 11 Hrs in 30 min subs

OIII 7.5 Hrs in 30 min subs

Date given is date of final capture.

Description: Allowed a bit more of the Ha signal in without losing the contrast in main part of nebula. I cannot decide if I prefer this version or the previous one.
