It's been over a week since I last imaged (due to moon and work conference). I thought I would try out imaging Eta Carinae for the first time. First thing I noticed was confirmation about how much temperature has an effect on noise. My recent project was the horsehead in about 25 degrees ambient temperature. Last night was a "chilly" 14. Makes a BIG difference with an uncooled dslr!
Anyways, here's 50mins worth of data.
Scope: 8" Newt
Mount: EQ6
Camera: unmodded Canon 400D
ISO800
Exposure: 10x5mins
Guidescope: 60mm f/11 tasco refractor
Guidecamera: unmodded toucam
Filter: Hutech LPS
Ambient temperature: 14 degrees
Windy at times
Stacked in DSS (lights, darks and flats) and processed using PS using some of the Astronomy Tools Actions.
