Astronomical imaging with Linux

Capture software

Update March 2018

Current release

Nicola Mackin FRAS has been developing new Linux capture software since June 2016. The software is called AstroDMx Capture for Linux.

The software can be downloaded at

I have been working on testing and some algorithms, while Nicola has done all of the coding. Below is an 8 panel high resolution mosaic of the Moon captured with AstroDMx Capture for Linux.

Everything has been captured under Mint Linux. The lunar images were captured as 1000-frame SER files at 1280 x 960 resolution using a ZWO ASI120 MC camera. The capture was in 8 bit RAW and was debayered on the fly by AstroDMx Capture for Linux.

The SER files were stacked (80% best images) in Autostakkert! 2.6 running in Wine. The resulting images were wavelet processed in Registax 5.1 in Wine and the 8 resulting images were stitched using Microsoft ICE running in Wine. The final mosaic was post-processed in the Gimp 2.9 running natively under Linux. The image is shown full size below.

Below are a sample of images captured by AstroDMx Capture for Linux, using DMK, DFK and ZWO ASI120 MC and MM cameras.
