IC434 - The Horsehead and Flame nebula

This is a two pane mosaic of the Horsehead area in Orion. I originally did the lower pane (the image below) but felt that a pane above this would give a sense of completeness in the image.

This is the first image that has taken advantage of the dual rig that I have got together.

Widefield

This is a single pane widefield image and you can see the difference between this image and the close up image below. 

This gives you a great feeling for how different telescopes at different focal lengths impacts on the apparent magnification of an object.

Close up

The Horsehead Nebula (also known as Barnard 33 and IC434 ) is a dark nebula in the constellation Orion. The nebula is located just to the south of the star Alnitak, which is farthest east on Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex. It is located approximately 1500 light years from earth. The Flame Nebula, designated as NGC 2024 and Sh2-277, is an emission nebula on the left hand side of the image.
