Horsehead Color Mosaic

horsheadmosaicrgb+ha

Here is the completed mosaic of the Horshead nebula, conisting of 4 panels of images. The color files total 6 hours of data, and the h-alpha is 12 hours of total exposure. The imaging began January 7 and ended January 20, 2015. My intent was to encompass the famous Horsehead structure to the right, and the Flame Nebula to the left. Both would not fit inside a single frame, hence the mosaic is stitched together. The bright star above is Alnitak, and it is so bright it overpowers the filters in the camera with some nasty reflections, but it’s pretty hard to keep them out. This image was a alot of work, especially aligning all the frames taken on different nights and under varying conditions. Click on the image for a larger view.
