Astronomical imaging with Linux

Capture software

Update July 2017

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

I have been working on specifications, algorithms and testing, 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 done 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 1.4.4.0 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.
