Description

It has taken 3 Years to capture all the data needed for this image, due to the the lovely cloud cover we have in Gauteng. I photographed all the images in my back yard, in the East Rand, using prime focus. Total acquisition time: 19 hours 10 minutes. Total processing time: 18 hours.

Equipment used:

4” William Optics Refractor GTF102 Aperture: 102mm, Focal Ratio: F/6.9, Focal Length: 703mm, Orion 10” Reflecting Astrograph Aperture: 254mm, Focal Ratio: F/3.9, Focal Length: 1000mm, SBIG STL11000M CCD Camera, Canon 60D Unmodified camera, HA, HB, OIII, SII and CLS Astronomic Filters, Orion Mini Auto Guider, Celestron CGEM Mount, All processing done using Pixinsight.
