Description

Shot the lights end of April and first half of May (2022).

Ik used 11.75 hours out of 17.00 hours because I had to select subframes carefully (low FWHM & eccentricity, high SNR).

Processed in a typicle way: Calibrated all the frames and splitted channels in WBPP (PixInsight). In 2 series, because I used gain 56 and gain 26 on my QHY 268 C camera.
Every sub is 51 Megabytes, poor laptop haha.

Aligned all subs (2 series) on Green reference frame.
That gave me 6 series for pre-processing.
After that, combined each serie to a color photo and combined 2 endresults with Pixel-math (PixInsight).
Stretched, used HDRM and off course saturation.

It was a long proces but in my opinion it was worth it.

Thanks for watching
