M27 with a tethered Canon 4000D and AstroDMx Capture for Linux

Nicola has been working on three versions of AstroDMx Capture: the Linux, macOS and Raspberry Pi (Pi versions 3B and 4B). This has involved building new tool-chains to enable the efficient compiling of the software. A test was performed on the night of July 5-6th.

A Canon 400D DSLR (with a 14 bit ADC) was directly mounted to an f/5, 150mm Newtonian and USB-tethered to a Fedora Linux laptop running the latest development version of Nicola's AstroDMx Capture for Linux. The software completely controls the functions of the DSLR. 30 x 60s exposures were captured of M27 along with 5 matching dark-frames.

The best 27 images were stacked in Deep Sky Stacker and the resulting image was post processed in The Gimp 2.10 and Affinity Photo and FastStone.

The software is approaching a new release with more features, particularly DSLR support and hardware acceleration.
