Software Downloads


If you find this software to be useful to you, please consider making a donation according to your means to help me continue to put in long hours, supporting and developing the software.

Some software developers call this coffee money in that, a donation of about 5 GBP is about the same as buying me a couple of cups of coffee. I think that this method is much better than requiring a user to buy a licence in order to have all of the features of the software. Whatever you decide to do, I hope that you enjoy using the software in a Linux environment.

AstroDMx Capture for Linux

AstroDMx Capture for Linux - Version 0.50.1

The 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 colour scheme has been inherited from the standard desktop theme.

AstroDMx Capture version 0.50.11

The latest version of AstroDMx Capture for Linux is 0.50.11. The software is distributed in three alternative packages and can be downloaded by clicking the following links.
