Orion H alpha 3 section Mosaic.
This image of the constellation of Orion was taken under clear moonless sky conditions with stars visible down to about magnitude 5.
I was using an Atik 383 L mono CCD camera piggybacked on my ten inch reflector mounted on a Vixen Atlux mount, a 50mm camera lens, and an Astronomik H alpha filter attached to the front of the lens.
I captured 3 minute sub frames with matching dark frames and combined them with flat field frames to reduce the effect of noise and vignetting in the final image. Each section of this composition had a total exposure time of 60 minutes . The colour data however was taken from some old data taken using the same camera and astronomik narrowband filters, Ha, O111, S11 and blue.
This mosaic contains Data from camera lenses and telescopes.
The colour data was taken using a 35mm lens and a set of Astronomik narrowband filters, Ha, O111, S11 and blue.
The luminance data however is a composition of data using a 50mm lens combined with a 200mm lens and data from a four inch and three inch f/6.3 refractors.
This image reveals the Witch head nebula, Barnard's loop, the Horsehead nebula, the Flame nebula, the Orion nebula, the Running man nebula and M78.
This 35mm lens shot contains combined data using 35mm lens , 50mm lens , 200mm lens and data from 80mm and 105 mm refractors.
