Description

I did an experiment with my new cooled DSLR from CentralDS, the CDS-600, thanks to Guylain Rochon at OTelescope. My goal was to reduce the amount of imaging time by increasing the ISO and shooting fewer and/or shorter exposures. This image of the Pelican Nebula represents a total of 30 minutes of exposures, six at 5 minutes each, ISO 3200, and fifteen matching dark frames. Just as an eyeball evaluation, there appeared to be about as much noise in these images as there was with my uncooled T2i at five minutes and ISO1600. This camera seems to be uber sensitive to red in general.
