M20 / NGC 6514 - The Trifid Nebula - July 2009

Date: July 9/09
Camera: DSI-IIC
Exposures: 40
Exposure Length: 30 seconds (guided in RA with ETX-90)
Gain: 63
Offset: 0
Filter: Orion Skyglow Filter (street lights, porch lights, 94% full moon)
Processing: Aligned, stacked in K3CCDtools using flat frame. Post Processing in Photoshop. Resized 70% of original.

Notes: Speaks for itself. This shot captured both the emission and the reflection nebula in 20 minutes of data, despite the light reducing impact of the Skyglow filter.

The DSI-IIC is a formidable camera, with a very respectable resolution. It may be time to retire my old modified ToUcam Pro.

Exposure Length: 10 seconds
Amp on setting: OFF
Camera Mode: RAW
Brightness: 100
Gamma: 60

Notes: A much nicer result than last time, although M20 was setting and I lost the last few frames due to trees. This was taken during the 2008 SSAA star party near Peterborough.
