Horsehead Nebula
Object: Barnard 33
The Horsehead Nebula - Dark Nebula
 Const.: Orion
Camera: STL11000M Scope: TEC 200FL Mount: AP1200
Filter(s): Hα Exposure: 16x8m blank
The dark nebula Barnard 33, also known as the Horsehead Nebula in Orion. This image is a stack of 16 eight minute exposures through an Hα filter using an SBIG STL11000M CCD camera on a TEC 200FL 8" f/8 refractor. The images were calibrated, stacked, wavelet sharpened, and a gamma stretch was performed using AIP4WIN V2.3.0. This image has been resampled down from its original size of 4008 x 2672.

The Horsehead Nebula - Dark Nebula
 Const.: Orion
Camera: SXV-H9 Scope: TeleVue NP-101 Mount: Losmandy Titan
Filter(s): L:R:G:B Exposure: 8x4m:4x4m:4x4m:4x4m TeleVue 0.8x Focal Reducer
The Horsehead Nebula region in Orion. This color image is a stack of 8 four minute exposures using a 4" f/5.4 TeleVue NP-101 refractor equipped with a 0.8x focal reducer. Each color channel is a stack of 4 four minute exposures. The images were calibrated, stacked and automatically color balanced using AIP4WIN. This image has been resampled down from its original size of 1368x1022.
 
Horsehead Nebula
Object: B33
The Horsehead Nebula
 Const.: Orion
Camera: HX-916 Scope: AP130 Mount: AP1200GTO
Filter(s): L:R:G:B Exposure: 60x60s:16x60s:16x60s:16x60s Color channels binned 2x2
The Horsehead Nebula (Barnard 33) is an oft-photographed dark nebula in Orion. This color image is a stack of 60 one minute exposures using a 5" f/6 refractor. Each color channel is a stack of 16 one minute exposures using 2x2 binning. The luminance image was calibrated, stacked and Gaussian histogram shaped. The color channels were G2V balanced and combined, all performed using AIP4WIN. This image has been resampled down from its original size of 936x1170.
