Object: NGC2359 Thor's Helmet	Emission Nebula	Const.: Canis Major
Camera: STL11000M	Scope: Vixen VC200L	Mount: Losmandy Titan
Filter(s): Hα:R:G:B	Exposure: 15x8m:5x8m:5x8m:5x8m	Binned 2x2
NGC2359 - Thor's Helmet in Canis Major. This image uses a stack of 15 eight-minute exposures taken through a hydrogen-alpha filter for the luminance channel (shown in the image below) and stacks of 5 eight-minute exposures taken through red, green and blue filters for the colors. The images were acquired using an STL11000M CCD camera on a Vixen VC200L 8" f/9 Cassegrain reflector. The raw images were calibrated, defect-corrected and stacked using AIP4Win V2. This image has been resampled down from its original size of 1960x1320.

NGC2359 - Thor's Helmet in Canis Major. This image is a stack of 15 eight-minute exposures taken through a hydrogen-alpha filter using an STL11000M CCD camera on a Vixen VC200L 8" f/9 Cassegrain reflector. The raw images were calibrated, defect-corrected, stacked, deconvolved and gamma-stretched using AIP4Win V2. This image has been cropped and resampled down from its original size of 1920x1280.
