Sh2-171
Object: Sh2-171
Emission Nebula
 Const.: Cepheus
Camera: SXV-H9 Scope: Tele Vue NP101is Mount: Losmandy Titan
Filter(s): Hα:R:G:B Exposure: 12x8m:7x8m:7x8m:7x8m
TeleVue
0.8x Focal Reducer
Sharpless 2-171, a.k.a Cederblad 214 in Cepheus. This image is an LRGB color composite of Hα, red, green and blue exposures acquired using an SXV-H9 CCD camera on a Tele Vue NP101is, equipped with its 0.8x focal reducer. The luminance image (shown below) is a stack of 12 images taken through an Hα filter. Each color is a stack of 7 eight-minute exposures. The exposures were calibrated, defect-corrected, stacked and color combined using AIP4WIN. This image has been resampled down from its original size of 1392x1040.
