Horsehead Nebula details

RegiStar Details
Full image

This composite image of the Horsehead Nebula was formed using a black-and-white photo and a color photo. The black-and-white image was taken by Rajiv Gupta using a refractor, and the color image by Peter Ceravolo using a Maksutov astrograph. The 2 images were matched by RegiStar, and a composite image was created using the Lab color model in Adobe Photoshop.
