Type: Planetary Nebula
Constellation: Velpecula
Date: 30 May 09 01.30am
Equipment: William Optics Megrez 90 Canon EOS 40D guided usin 66mm William Optics refractor & Atik 16IC camera.
Subframes: 1 x 8 minute exposures at ISO800, 1 x 8 minute dark, Bias & light frame calibrated
Stacked: by Deep Sky Stacker.
Processed: In Images Plus 3.75 with a DDP stretch.
Notes: This is the first opportunity to guide using my new Atik 16IC camera. I was able to guide using what I estimate to be a 9th Mag star. I am seeing a much better signal to noiseratio by generating a longer exposure rather than 16 x 30 seconds. I look foward to future tests.
