Description

The stars that form the constellation Monoceros may be of lower magnitude than the stars comprising other constellations, but this area of the night sky contains some prominent and well-known targets.  A beautiful collage of dust, emission and reflection nebulas with colorful stars of varying age and distance.  

This wide field, broadband image was taken using a 32-year old Nikkor 300mm f/4 ED-IF lens with the aperture set at f/5.6.  The lens has a built-in ring that was bolted to a dovetail plate and coupled with ASI294MC camera and placed on an old Celestron AVX mount.   Final image is a stack of 176 sub-frames at 300s exposure (15 hr 40 min integration time).

Note: the star diffraction spikes caused by the iris blades in the Nikkor lens were removed by applying a luminance mask generated from an image of this area of the sky collected using a RedCat51 and ASI2600MC camera.

Clear skies everyone!  🔭
