Object:Gum 12 The Gum Nebula	Supernova Remnant	Const.: Vela
Camera: ST-10XME	Scope: Tele Vue NP101	Mount: AP1200
Filter(s): Hα:Hα:OIII:OIII	Exposure: 8x8m:8x8m:11x8m:11x8m	0.8x Focal Reducer
The supernova remnant Gum 12 in Vela, a.k.a. the Gum Nebula, a.k.a. the Vela Supernova Remnant. North is to the right in this image. The luminance channel for this image is a stack of 8 eight minute exposures using an Hα filter. The same Hα exposure was used for the red channel. A stack of 11 eight minute exposures using an OIII filter was used for both the blue and green channels. The individual Hα and OIII filtered images are shown below. 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 2130x1460. This image was taken at the Lake Atitlán, Guatemala observatory of Adriana Sherman
