Hello, this image was taken years ago. It is composite of 80 images taken with a Santa Barbara Instruments ST-10, 6-meg, water-cooled, dual-chip camera. One chip is for guiding the equatorial telescope mount, the other is for taking the images. The lens used was an Astro-Physics 750mm, 5 inch, F5.6, telescope. The camera is special in that it is a B&W camera using color filters. To reduce noise brought on by heat in the camera, the camera is water cooled and images are stacked using special astro software.
