Description

Test shot with the backlit QHY268c of a rich area including emission, reflective nebulae and open clusters embedded in the Milky Way. There are four NGC, also an Messier object plus varius dark nebulae. In Sharpcap Pro I utilized "The Brain" app to calculate the exposures. It calculated sky backround of an adu of 2.3 per pixel. The recommended results were 118 exposures @ 28 seconds with a gain of 30 and a pedestal of 11. This amounts to 55 minutes total. Weee... Binned 1.5 to 1. I have a lot to learn about how to process but hey, what else to do these days.
