Horsehead Nebula Image from new Dean Glace Telescope

Sunday, November 1, 2009 - 12:00am

The image at right is the "first light" color composite image taken the first night of use of the Dean Glace telescope.

Dean took four separate images through red, green, blue and clear (for luminance), filters. Each image was 200 seconds long. These were then aligned and combined with MaximDL to produce the color image.

This is an excellent image, especially considering that it has not been dark-subtracted or flat-fielded!
