Description

With my friend Victor Van Puyenbroeck we shared data and processed separately the dataset.
Victors version is visible here: https://www.astrobin.com/417476/H/?nc=user

Data capture: Axel and Victor Van Puyenbroeck
Image processing: Axel

Axel :
Paris, France (Bortle 8-9)
EQ6-R + Skywatcher 80ED f/6.4 + ASI1600MM-C + ZWO 7 nm filters
555 minutes OIII
183 minutes Ha
Acquired in June 2018 and June 2019

Victor :
Herent, Belgium (Bortle 7)
EQ6-R, EQ5 + TS 80mm f/4.8 + ASI1600MM-C + ZWO 7 nm filters
530 minutes OIII
520 minutes Ha
30 minutes Blue
20 minutes Green
20 minutes Red
Acquired between 09-Jun-2019 and 22-Jun-2019

Total integration time: 31 hours

Victor opted for a tonemap version whereas I went for a more straight forward approach based on the following blend
R = H
G = H*.35 + O*.65
B=H*.1 + O*.9
The soap bubble is here but less visible than in Victor's image.
