Description

Edit info: Added image version C & D.

Raw frames taken during 3 nights in Amager, CPH, DK, where the moon was present in the sky.
It's summertime in CPH DK and the sky is bright all night, meaning it's never dark at this time of the year, but I was lucky there was a clear sky, no clouds, low wind, ... .

Narrow FOV, 16" SCT F6.2 FL app. 2.5meters, ZWO asi294MM pro cool camera and 36mm Lum,Ha,RGB Baader filters & wider FOV, WO FLT-110 F7 FL app. 770mm, ZWO asi1600MM cool camera and 36mm Lum,Ha/OIII/SII Baader filters.

Subs/frames was calibrated with darks & the wider FOV also with flats.
Plan to reprocess the 16" scope image when flats frames are taken/ available!

Please also check image versions B C & D.

As usual it's taken in a light polluted area, Bortle 6 sky looking south, Bortle 7 sky the other directions/surroundings.

My home build observatory is placed in my front yard/in the "red light" pollution zone, have a look here,

Red Zone

Kind regards Niels
