Although not straightforward, we have installed 32-bit Debian on our Asus EeeBook
Nicola has compiled a 32-bit version of AstroDMx Capture for Linux.
The 32-bit version of AstroDMx Capture for Linux saw first light by imaging the 97.6% waxing, gibbous Moon.
A QHY 5L-II-M camera was placed at the Cassegrain focus of a Skymax 127 Maksutov and the 32-bit version of AstroDMx Capture for Linux was used to capture 2,500-frame SER files of two overlapping regions of the Moon in the Copernicus, Kepler, Reiner Gamma region.

The best 75% of the frames in each SER file were stacked in Autostakkert!, wavelet processed in Registax 6, and post processed in The Gimp 2.10. Microsoft ICE was used to stitch the two resulting images into a two-pane mosaic.

It is hoped that the 32-bit version of AstroDMx Capture for Linux will give a new lease of life to older or low spec newer laptops and netbooks as Linux imaging machines.
DSLR Live-View
Nicola has also implemented Live View for supported DSLRs. It should be noted that Live View is not a high-resolution view and the actual resolution is camera specific, with a maximum of full HR resolution. However, Live View can be used as an initial focusing aid before putting the software into the DSLR Loop function to repeatedly show preview images at high resolution to refine the focus, before stopping the Loop and starting the capture of images.
The Live-view functions were tested in AstroDMx Capture for Windows but will be present on all platforms. This is quite an exciting implementation as it provides more functionality than is normally found in Live-View. This will be reported on when the implementation is complete.
A Canon EOS 4000D DSLR was placed at the Cassegrain focus of a Skymax 127 Maksutov and the camera was tethered to a Windows 10 laptop running AstroDMx Capture for Windows.

The image can be scaled as usual to aid with focusing.

When all of the new functionality of the DSLR Live-View has been implemented it will be released as a new version of AstroDMx Capture for Linux, and will be fully implemented in the macOS and Windows versions before release.
