[attachment]NGC6888 RCOS & WO.jpg[/attachment]
I decided to combine the data of NGC6888 made with the 132mm F/5,6 WilliamOptics APO (pier7) and the 12,5inch RCOS Ritchey Chretien telescope (pier12).
The imagescales of the setups are comparable so it makes sense to give it a try.
The processing has been done in PixInsight.
It's a HaOII-RGB image with a total of one day and 30 minutes integration time
