Clusters and nebulae in Gemini and Orion
The first clear night for some weeks!
17 x 4-minute exposures at f/4.5 and ISO 1600. Astro-modified Canon 600D and Canon 100mm f/2.8 lens piggybacked on a Celestron C8 telescope for tracking.
Frames stacked in Deep Sky Stacker software. Result post-processed to increase contrast, reduce noise and reduce colour gradients (caused by light pollution). I also used Noel Carboni's astronomy tools in Photoshop Elements to reduce the prominence of the stars (which otherwise dominate after stretching the contrast).
