High resolution 88% waning Moon images with AstroDMx Capture for Linux and a DMK 37AUX273 camera

A Skymax 127 Maksutov was mounted on a Celestron AVX, EQ, GOTO mount. An Imaging Source DMK 37AUX271 machine vision camera was placed at the prime focus. AstroDMx Capture for Linux was used to capture 8 overlapping, 2000 frame SER files of the 88% waning, gibbous Moon in High contrast and terminator areas, as well as the Copernicus/Kepler region.
(All running in Wine), Autostakkert! 3.10 was used to stack the best 80% of the SER file frames, Microsoft ICE was used to stitch the resulting images together and Registax 5.1 was used to wavelet process the resulting Mosaic. The resulting high resolution mosaic was post processed in the Gimp 2.10.
The scope was protected from the intrusive light from a nearby garden lamp by means of an occultation board which cast a shadow across the scope.

The DMK 37AUX273 can be considered to be an excellent Lunar and Solar imaging device. Seeing was too poor to gather worthwhile planetary images as Mars and Saturn were far too low in the sky. However, a test showed that high frame rates could be achieved capturing monochrome planetary data through this modest 5" Maksutov. Larger, planetary imaging scopes would cope even better.
