Emission and Dark Nebulae in Orion

This image of The Flame and Horsehead nebulae was taken by Chris Callaway on the 17th and 18th January 2024. It comprises 120 x 30 second subs of one shot colour taken using a Takahashi 106 telescope and Altair 26C camera on a Paramount MyT mount. Chris added 12 x 600 seconds of Hα data which he took a year ago with his Atik 16200 camera.  Image Credit: Chris Callaway.

Dave Selfe captured the following wide field image of the Horsehead and Flame Nebulae on the 26th February 2022. The Horsehead Nebula (Barnard 22) appears as the dark notch in the red streak of the emission nebula IC434, below the bright star Alnitak at the left of the image. The Flame Nebula (NGC 2024) is visble next to Alnitak in the 10 o'clock position relative to that star. Alnitak is the left-most star of Orion's belt as seen from the northern hemisphere. The middle star of the belt, Alnilam, is also visible in the upper right quadrant of this image. Dave used a Nikon D750 camera with an Optolong L-eNhance filter through a Skywatcher Esprit 100ED telescope. The image comprises 81 x 30s exposures at ISO 800.  Image Credit: Dave Selfe.

Separate images of NGC 2024 and IC 434 were captured by Peter Branson on January 20th and 21st 2022, and comprise 86 minutes of total exposures of NGC 2024 and 80 minutes in total for IC 434. The camera used was a ZWO ASI533 cooled colour camera together with a 102mm TS Optics Photoline f7 telescope with a Hutech IDAS light pollution filter and field flattener attached mounted on an NEQ6 mount. A filter wheel fitted with LRGBHa filters was used to capture both L and extra Ha for both images. The two square frame images were combined in Microsoft Images Composite Editor (ICE). Peter says - "One of my challenges this winter is to get some decent images of parts of the Orion Nebula. I'm experimenting with my new ASI533 camera and, although it's a colour camera, I've been taking images through an L filter and an Ha so that I can add extra Ha detail to the images if necessary. I was pleasantly surprised to find that Microsoft ICE produced this lovely panoramic view when they were combined."  Image Credit: Peter Branson.

The following image of NGC2024 The Flame Nebula and IC434 The Horsehead Nebula was created with data taken by Chris Callaway on the 10th, 12th and 25th February 2021 from Coalville. The image comprises 17 x 5 minute subs of Ha and 16 x 5 minute subs of Oiii and Sii. Equipment was a Takahashi 106, the camera was an Atik 16200 with Atik filter wheel and filters, the mount was a Paramount MyT. The images were stacked in Astroart with further processing taking place in Photoshop. Ha was assigned to Red, Oiii to Green and Sii to Blue.  Image Credit: Chris Callaway.

This image of the Horsehead Nebula was captured by Peter Branson on the 21st February 2014. To the left of the image is another emission nebula called The Flame Nebula (NGC2024). The picture is made up of 9 separate images of 150 seconds each, all taken at ISO 1600. The images were stacked in Deep Sky Stacker and then the final image processed in GimpShop. The separate images were taken with a Canon 1100D attached to TS Photoline ED102 refractor telescope with field-flattener and Hutech IDAS light pollution filter attached. The telescope was guided using an Orion Mini autoguider controlled by PHD software.  Image Credit: Peter Branson.

Mike Lancaster captured this image of The Horsehead Nebula on the 20th February 2014. It is a stack of six frames of 120 seconds each taken with a Mallincam Xtreme X2 camera at AGC 5 using an MFR5 focal reducer and Astronomik CLS-CCD filter through a 10" Meade LX200 ACF SCT. No guiding was employed and Mike had to contend with some drifting high cloud. The images were stacked, cropped and processed in Nebulosity v3 with further processing using Photoshop Elements and Astronomy Tools.  Image Credit: Mike Lancaster.

This image shows the Horsehead Nebula at upper right with the Flame Nebula (NGC 2024) at left. It was taken by Adrian Brown during January and February 2012 and he comments that it was supposed to be a colour image but at the time he only managed to collect the red filtered data. It is comprised of sixty exposures of 6 minutes each taken with his Skywatcher 80EDPro refractor, an ATIK ATK16HR camera and Astronomik red and CLS light pollution filters.  Image Credit: Adrian Brown.

This image of the Horsehead Nebula was imaged over a few nights in December 2006 and January 2007 by Adrian Brown. It was created from seven 30 minute exposures through a 6nm Astronomik hydrogen-alpha filter. For imaging Adrian used an ATIK ATK16HR camera through a Skywatcher 80ED Pro refractor at f7.5. This was guided using an ATIK ATK-2HS camera through a Skywatcher 80T refractor. The set up was mounted on a Celestron CGE mount.  Image Credit: Adrian Brown.

Adrian Brown took the following image of the Horsehead Nebula (Barnard 33) which is silhouetted against the emission nebula IC 434. The bright star to the left of the Horsehead is Alnitak (Zeta Orionis) - the leftmost star in Orion's Belt as seen from the UK. The Flame Nebula (NGC 2024) lies below Alnitak and has a dark tree-like structure of dust lanes superimposed against it. This earns NGC 2024 its other name of The Christmas Tree Nebula. The bright star in the upper left corner of the picture is Alnilam (Epsilon Orionis), the middle star of Orion's belt. Hence north is to the left in this picture and we are actually seeing Orion on its side in this view. Adrian took this picture during the early hours of Friday, 4th November 2005. It was created from 2 hours and 20 minutes of exposure (14 x 10min) taken with an ATK-16HR CCD camera, an Astronomik 13nm Hydrogen-Alpha filter and Chris Newsome's Vivitar 75-205mm f/3.5 zoom lens which was set to 135mm and f/5.6.  Image Credit: Adrian Brown.
