Description

Ha: 22x30min L: 50x10min R: 40x10min

S: 15x30min G: 31x10min

O: 12x30min B: 32x10min

A: R:G:B S:Ha

B: Kindly processed by Eric Coles using Tone Mapping technique. Thank you Eric

C: I combined raw Ha, O and S then process coloured image, instead of preprocess each channel separately as in Image one. I believe the nebula and its core have more of natural appearances and detail revealed.

D: reprocessed

E: L:R:G:B 10:40:31:32 of 10min sub.

F: L:R:G:B + Sii 50:40:31:32 of 10m sub each and 15x30min Sii
