Installation

eQuimage is developed in Python 3 with a GTK3 graphical interface. Python 3 and the GTK3 library are available in all Linux distributions; On Windows, follow https://www.gtk.org/docs/installations/windows/ for GTK3. To install the latest stable version of eQuimage, open a linux terminal/windows command prompt and run:

pip install --user eQuimage

pip will automatically download eQuimage and the missing python modules if necessary (matplotlib, etc...). You can then launch eQuimage by typing:

eQuimage

in this same terminal. You can also create a link to eQuimage from your desktop; an icon is distributed for this purpose with the python package.

Usage

This code has no claim and only offers elementary operations compared to other more advanced image processing or astrophotography software (GIMP, PixInsight, etc...). Its main advantages are:

• to highlight the pixels "blackened" or saturated by the treatments (in each R/G/B channel),
• to leave the frame of the Unistellar images unprocessed (option only implemented to date for the eQuinox 1 telescope, but feel free to contribute or send me sample images from other telescopes !)
• to keep track (in a log file) of all operations applied to a given image.

There is no documentation yet, but you should find your way around easily if you have used image processing software before. The python code itself is documented in English.

Known bugs

• On windows, the main window (displaying the image) does not always refresh after an operation. Simply moving the cursor shall trigger the update.
