Astro-Imaging Applications for Linux and macOS


AstroDMx Capture for Linux version 0.68.1 is now available. This version provides full support for the SVBONY SV305 camera, implements a new high quality debayering algorithm, allows exposure values to be typed into the associated text box and fixes various problems with QHY cameras. See the changelog for more information.

AstroDMx Capture for Linux versions greater than 0.50.x have much improved performance for slower computers, have a hardware acceleration mode and support many DSLR cameras. In addition to this, AstroDMx Capture for Linux will be released for Apple macOS early 2020.

What is AstroDMx Capture for Linux?

AstroDMx Capture is a fully featured astronomical image capture application for 64-bit Linux Operating Systems, the Raspberry Pi3 and Pi4 and soon to be released for macOS. It is a deep sky and solar system imager.

The project was started by Nicola Mackin FRAS in order to produce a stable astronomical imaging application for use with the Imaging Source DMK, DFK and DBK range of cameras. Since then, the project has grown into a fully featured capture application written specifically for the Linux platform.

This screenshot is of AstroDMx Capture displaying a live preview from the ASI178MC running in 16-bit mode. AstroDMx is mapping the 16-bit stream onto the preview screen by using one of the new 16-bit to 8-bit transforms available in 0.50.1. The dark theme has been inherited from the operating systems base theme.
