Description

Just past the meridian as darkness descends and disappears into the West soon after. Managed to gather 90 minutes on the past three nights in RGB, the sky is still to light for any Luminance in the west. My Astro darkness is down to two hours now and will be totally gone next week.
Still a lovely pair of galaxies made for my FOV.

B

Caught this odd satellite trail, or ufo, as it spiralled through the 300s sub. It looks like it passes straight through the centre of the galaxy.

C

Chucked out a few bad frames and removed a lot of satellite trails. Ten images contained at least one. A cleaner image.
