NGC7293
Object: NGC7293
The Helix Nebula - Planetary Nebula
Const.: Aquarius
Camera: SXV-H9 Scope: Tele Vue NP-101 Mount: Losmandy Titan
Filter(s): Hα:R:G:B Exposure: 8x16m:5x8m:5x8m:5x8m blank
The Helix Nebula, NGC7293 in Aquarius. This image is a stack of 8 sixteen minute exposures shot through a Hydrogen-alpha filter, combined with red, green and blue filtered exposures integrated for 40 minutes each. The H-alpha image used for the luminance channels is shown in the image below. The exposures were acquired using an SXV-H9 CCD camera on a Tele Vue NP-101 4" f/5.4 refractor. The exposures were calibrated, defect-corrected and stacked using AIP4WIN. They were automatically G2V-balanced and combined using AIP4Win's automated color tools. This image has been resampled down from its original size of 1392x1040.

The Helix Nebula, NGC7293 in Aquarius. This image is a stack of 8 sixteen minute exposures shot through a Hydrogen-alpha filter. The exposures were acquired using an SXV-H9 CCD camera on a Tele Vue NP-101 4" f/5.4 refractor. The exposures were not calibrated, just filtered for hot pixels and stacked using AIP4WIN. This image has been resampled down from its original size of 1392x1040.

Camera: SBIG STL11000M Scope: Tele Vue TV-102iis Mount: Losmandy Titan
Filter(s): Exposure: 8x8m
0.8x Reducer-Corrector
This image shows NGC7293, The Helix Nebula in Aquarius. This image was acquired using an SBIG STL11000M CCD camera mounted on a Tele Vue TV-102iis with a 0.8x reducer-corrector. This image is a stack of 8 eight-minute exposures taken through a Hydrogen-alpha filter. The images were calibrated, defect-corrected and stacked using AIP4Win Version 2. This image has been cropped down from its original size of 4008x2672.

The Helix Nebula - Planetary Nebula
Const.: Aquarius
Camera: HX-916 Scope: Vixen R200SS Mount: Losmandy Titan
Filter(s): L:R:G:B Exposure: 35x2m:10x2m:10x2m:10x2m Color channels binned 2x2
NGC7293, the Helix Nebula in Aquarius. This color image was created from a 70 minute luminance image stack and 20 minute red, green and blue image stacks. The luminance channel was taken using 1x1 binning, while each color channel was acquired using 2x2 binning. The grayscale image below was used as the luminance channel. The images were combined and balanced automatically using AIP4WIN's automated color tools, using the G2V Color option. The images were taken using a Vixen R200SS 8" f/4 Newtonian equipped with a Paracorr. This image has been resampled down from its original size of 1267x1014.
