Image Parameter Details
Image Date (UTC): 2010-10-24
Image Time (UTC): 01:45 - 02:15
Exposure: 45 x 30s + 10 x 180s
Filter: Astronomik CLS/HA/OIII/SII
Field of View: 80'
Observing Site: Cherhill, Wiltshire UK
Observing Equipment: TMB105 f/6.2 refractor
Atik 4000 CCD
Digital Processing: Tricky to knock out the Moon, uses gradient xterminator/Noels actions/CS5; Maxim DL DDP/SD/and Median Combined layers
Comments: Very difficult to process due to the extremely bright and close by Moon. The use of narrowband filters helped a lot, as did the gradient xterminator plug in.

To clarify this (now that it's morning!). This is a DDP processed image using MaXIM DL, which is a combination of around 45 x 30s + 10 x 180s exposures using a CLS light pollution filter. Then using the RC Gradient xterminator, the moonlight caused gradient removed.
