A problem now fixed with the .rpm installer of AstroDMx Capture for Linux


Nicola has discovered a problem that she has now fixed. This is what she has put on the website: https://www.linux-astro-imaging.uk/
There seems to be a permissions problem with the RPM release of 0.50.11. Nicola has uploaded a new version 0.50.11.1 to fix this problem. The faulty version has been taken down and replaced with the new version. The version number allocated to the new .rpm installer will keep the version numbering in sync for future releases.

The future direction of AstroDMx Capture development

Nicola has been working very hard on AstroDMx Capture, and there are a number of developments in the pipeline. She works very long hours on the project which is now an enormous code base.

A picture is supposed to be worth a thousand words, so the following splash-screens show the current development direction. The detail says it all.




The project is now almost three years old and it is to be hoped that Nicola retains her current level of enthusiasm for further development. So many projects that are essentially freeware eventually stall through lack of motivation. We can all think of them.
Releases will be made when we are sure that the software is fully stable.
There is another, secret project that will be revealed in due course.

DSLR tethering, AstroDMx Capture for Linux and AstroCrop for Linux

A Canon EOS 4000D DSLR was placed at the Newtonian focus of an f/5, 130mm Newtonian. The camera was controlled by USB tethering to a Lubuntu Laptop running AstroDMx Capture for Linux. 100 images of the Moon were captured as tiff files.
The images were initially very large, with lots of black space

Single, unprocessed image

The 100 images were precisely cropped to 1600 x 1600 pixels in Nicola's AstroCrop for Linux.

The best 90% of the cropped images were stacked in Autostakkert! and wavelet processed in Registax 5.1, both running in Wine. The resulting image was post processed in the Gimp 2.10.

86%, Waxing, gibbous Moon

The version of AstroDMx Capture for Linux with DSLR tethering support will be released after further testing.
