M42/M43 with AstroDMx Capture for Linux, an SV305 camera and a 130mm, f/5 Newtonian

An SVBONY SV305 camera, fitted with an SVBONY UV/IR cut filter was placed at the Newtonian focus of a Skywatcher Explorer 130 PDS 130mm, f/5 Newtonian, mounted on a Celestron AVX GOTO EQ mount.
AstroDMx Capture for Linux, running on a Ubuntu computer was used to capture 16 bit Tiff images of M42/M43: 40 x 2s; 60 x 8s and 20 x 16s, all with matching dark-frames.

The images were stacked for each exposure in Autostakkert!3
The 3 images obtained were post processed in the Gimp 2.10 and combined in the Gimp to produce the final image.

Nicola has implemented some additional functionality of the SV305 in AstroDMx Capture for Linux, not found in Windows capture software. This will be incorporated into the next release of AstroDMx Capture for Linux and will be discussed in a future post.
