ImPPG performs Lucy-Richardson deconvolution, unsharp masking, brightness normalization and tone curve adjustment. It can also apply previously specified processing settings to multiple images. This time everything is wrapped in a full-fledged GUI, whose operation should be familiar to most amateur astrophotographers.

Some of the interface features:
- freely adjustable processing area (selection) within the image
- non-blocking operation; if you change the selection, previously started processing (if any) aborts and begins for the new selection
- for moderately small selections the application of Lucy-Richardson deconvolution is almost instanteneous, which allows for convenient fine-tuning of the "Sigma" parameter
- tone curve editor with helper functions (invert points horizontally to create a negative; stretch the curve to cover the histogram only)

Screnshots:
The "Prevent ringing" function is highly experimental and may not help in all cases. It aims to reduce ringing around overexposed areas (e.g. a solar disc in a prominence image); it does work quite well in the case I devised it for:

no deringing: deringing enabled: but your mileage may vary.

For now only BMP and uncompressed TIFFs (8- and 16-bit) are supported, but I'll add support for more formats (including FITS) soon. The program can be built on any platform which has a C++ compiler supporting Boost and wxWidgets libraries, including Linux (which I use on my laptop) and OS X. As usual, additional details can be found in the README file.

ImPPG is free & open-source, licensed under GNU GPL v3 (or later). Source code and Windows version (32- and 64-bit) can be downloaded from:

Looks like a great front-end to what was already a very impressive bit of software

Hi Filip

thank you so much. I'll have a go with it for sure

an excellent resource, i shall have to give it a try!

Hi Filip

it works (tested it on a SAFIX test shot from friday) , but I do not understand it yet

Walter, all there's really to do is play with the sliders

Of course, if anything is unclear, please post your questions here.

Thanks! I have downloaded it and will have a try

I have been a great fan of ImPP for my mosaics, so I will give this further development a try as soon as I can.

New version: 0.1.1
Bug fixes:
– Blank output files after batch processing when L-R iterations count is 0

Thank you Filip
