Emission Nebula
Const.: Monoceros
Camera: ST-10XME Scope: Tele Vue NP101 Mount: AP1200

The emission nebula Van denBerg 93 in Monoceros. The luminance channel for this image is a stack of 16 eight minute exposures using an Hα filter. The same Hα exposure was used for the red channel. Stacks of 6 eight minute exposures using green and blue filters were used for both the green and blue channels. All images were acquired with an ST-10XME CCD camera through a Tele Vue NP101 4" f/5.4 refractor with a 0.8x focal reducer. The images were calibrated, stacked and color-combined and automatically color-balanced using AIP4WIN V2. This image has been resampled down from its original size of 2184x1472.
This image was taken at the Lake Atitlán, Guatemala observatory of Adriana Sherman
