Hydrogen-α, Sulfur II & Oxygen III
NGC2264 & Sh2-273 in H-α & OIII
Object: NGC2264
& Sh2-273
The Cone Nebula - Emission Nebula
Const.: Monoceros
Camera: SXV-H9 Scope: Tele Vue NP101 with a 0.8x FR Mount: Losmandy Titan
Filter(s): Hα:Hα/SII:OIII:OIII Exposure: 9x8m:9x8m/5x8m:10x8m:10x8m TeleVue 0.8x Focal Reducer
NGC2264 and Sh2-273, the Christmas Tree Cluster and the Cone Nebula in Monoceros. The region to the right of the bright star above the center is known as the Fox Fur Nebula, while the open cluster in the center is called the Christmas Tree Cluster. This image is a composite, using a Hydrogen-alpha filtered image for the luminance channel, the same Hα combined with a Sulfer II filtered image for the red channel, and an Oxygen III filtered image for both the blue and green channels. Since all the color seen in the nebula is the result of these three emission lines, the color is reasonably accurate. This technique allows color imaging to be performed in a light-polluted environment. The exposures were acquired using an SXV-H9 CCD camera on a Tele Vue NP101 101mm f/5.4 refractor equipped with a 0.8x focal reducer. The exposures were calibrated, defect-corrected, stacked and color-composited using AIP4WINV2.

The Cone Nebula - Emission Nebula
Const.: Monoceros
Camera: SXV-H9 Scope: Tele Vue TV-60is Mount: Losmandy Titan
Filter(s): Exposure: 12x8m TeleVue 0.8x Focal Reducer
NGC2264 and Sh2-273, the Christmas Tree Cluster and the Cone Nebula in Monoceros. The region to the right of the bright star above the center is known as the Fox Fur Nebula, while the open cluster in the center is called the Christmas Tree Cluster. This image is a stack of 12 eight minute exposures shot through a Hydrogen-alpha filter. The exposures were acquired using an SXV-H9 CCD camera on a Tele Vue TV-60is 60mm f/6 refractor equipped with a 0.8x focal reducer. The exposures were calibrated, defect-corrected and stacked using AIP4WIN. This image has been resampled down from its original size of 1392x1040.
