Description

The summer has proven challenging weather-wise here in the UK. The original plan was for 5 hours each of SII, Ha and OIII on this object. I got pretty close to completion last night before the clouds rolled in. I have decided to call it therefore, even though I am still 4 subs short of target. This is my Esprit 120, with QSI 690 atop a Mesu 200 in my home observatory.

Data captured between 27 May and 19 August 2017. Jings that is one image per quarter - told you it had been challenging.

B

Significant rework. More fine detail in black dust and better colour balance.

D

Significant rework. Extracted Lum from SHO (RGB) image. Then removed stars from 'RGB' image, and wored on Lum and RGB separately. This allowed me to be a bit bolder with the colours and show some detail (via the extracted Lum).
