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