The Trifid, Lagoon and Chinese dragon nebulae region with an SVBONY SC571CC 16 bit OSC camera.

For this test we used an Askar 71F quadruplet apochromatic astrograph refractor paired with an SVBONY SC571CC 16 bit OSC camera. The scope was fitted with an iOptron iEAF motor focuser and an Altair V2 magnetic 2” filter holder containing an Altair Quadband filter. AstroDMx Capture for Linux x86_64 running on an Ubuntu Linux mini computer was used to capture the image data as FITS images with  matching darks, flats and dark-flats. 24 x 5 minute exposures centred on the star HD165132 (in order to frame the image) were captured. The data were stacked and part processed in PixInsight and further processed in GraXpert, SetiAstroSuitePro and Gimp3. The image includes the Trifid, Lagoon and Chinese dragon nebulae as well as a number of other NGC and IC objects.

Annotated version of the image

This imaging session session demonstrated again that the SC571CC 16 bit OSC camera is extremely capable and is a good match for the Askar 71F. The field was flat right to the corners of the image.
