Quick Silver Coin
This image is made up of four 120sec subs, one each of L, R, G, B. They were all that I recorded on a night terminated by an attack of large Christmas Beetles (!) which could have damaged mirrors......
The L was binned x2 (.64"/px) and the colour frames x4.
With no expectations, I processed the set in Pixinsight, NXT, and BXT.
Equipment: Officina custom-built 300mm f/8 RiDK: Moravian C1X61000; Astrodon Filters.
8 minutes total exposure; Image FOV 43' x 34'
