Description

First image to come out of my new setup. Data captured from my parents back garden about 25 miles West of London in Bortle 5 skies. Mostly during February but some colour data captured in March.

Happy with how this has come out - main issue is with the secondary mirror heater being too big and causing additional uneven diffraction spikes, exasperated by capturing red and green data on one side of the Merridian and then the blue after a flip. Have tried to keep the uneven diffraction patterns around the brightest starts under control. Bit short on colour data, and would like to add some Ha data, but that's now a project for next year.

L: 224 x 2mins = 7.5 hours

R: 12 x 5 = 1 hour

G: 12 x 5 = 1 hour

B: 18 x 5 = 1.5 hours

Description: Went back and reprocessed this data again to see how it would come out without drizzling - big improvement it seems; drizzling did indeed add a load of noise without any benefit to the resolution.
