Rosette Nebula (caldwell 49)

Description

2.25 hours of RGB. It lacks the pronounced red color of the hydrogen alpha emission prevalent in most images of the Rosette because Canon mistakenly removed the baader filter and replaced it with the original stock canon IR block filter when I sent it back to them for repair.

Date of Shoot 8th December 2010

Camera: Canon 5D Mark II (modded by HyperCams & Mods)

9 x 15 min sub exposures with flats and dark frames.

Scope: TMB 130SS using WO/TMB 68mm Field Flattener.

Autoguided with Orion Auto Guider on Stellarvue 10x60

Mountain Instruments MI-250 Mount

Image Acquired using Nebulosity II, stacked with Deep Sky stacker and processed with Photoshop CS3.
