Lagoon Trifid in RGB
« on: 2015 May 03 17:41:50 »
Data 15x5 min for each of RGB.

I routinely use RBI at the lowest practical sensor temperature. Dithering is also used. My master bias is from 100 frames and the master dark from 60 frames. The master flat is also produced by at least 30 frames. This minimises injecting noise into data.
