NGC 2023 - Horsehead and Flame Nebulae
The Horsehead and Flame Nebulae region in the constellation Orion. The horse head shape is silhouetted against a backdrop of illuminated hydrogen gas.
This image was taken from Samphran, Thailand, using a 300mm F3.0 telescope, and is the result of approximately 39 hours taken through L, R, G, B, Hydrogen-alpha and Sulfur 2 filters. Imaged and processed in Samphran, Thailand by the SC Observatory team: Mike Selby, Stefan Schmidt and Andy Chatman.

Orion-The Edge of Forever
The Horsehead Nebula, captured from GrandMesaObservatory.com in Purdy Mesa, Western Colorado using the Holloway Takahashi 130 FSQ and QHY367C Full Frame CMOS camera.
I acquired the data in Color + H-Alpha, OIII and SII over 4 nights, processed here are versions in RGB, HaRGB with Ha mapped to red channel and also used as Luminance layer, H-Alpha only and finally a Hubble Palette version with SII, Ha and OIII data mapped respectively to the R, G and B channels to create a Hubble Palette (SHO) rendering.
Total Integration time 20.5 hours

Horsehead nebula in Orion [H-alpha] (robotic, NM)
The iconic Horsehead dark nebula in Orion (Barnard 33). Backlit by the extensive billowing clouds of excited hydrogen gas in emission nebula IC 434.
This was a narrowband image comprising 6 x 6 minute exposures on the T21 scope in New Mexico.
Hydrogen alpha filter used.
Planewave CDK430mm aperture. 1939mm focal length at f/4.5
From the resulting black and white image which was integrated in PixInsight, I used a gradient map in Photoshop to add false colour

The Horsehead, Flame and IC434 Nebulae
Covering 3.48 x 2.18 degrees captured over 4 seasons using LRGB + H-Alpha filters showing the immensity of the bright Emission Nebula IC434.
This is a combination of data captured from my backyard observatory in Western Michigan between 2011 and 2014 using QHY9 and QHY11 Mono CCD’s, 5 inch TMB 130 and TMB92 refractors, AT12RC and Takahashi E180 Astrographs, processed with CCDStack, Registar and CS5
