GraXpert new software for gradient removal

[frasax]

Hello community,

I am Frank, the initiator of GraXpert, a free and open source standalone tool that makes removal of gradients in deep-sky photos easy and free, and provides - as we believe - high quality results. We just released GraXpert (RC1) for the first time earlier this week. We provide both the source code as well as binary releases for Linux (tested on Ubuntu 20.04), Windows (>10), and MacOS (>10.15) on github.

The project: https://github.com/Steffenhir/GraXpert

Releases: https://github.com/S...aXpert/releases

The license: https://github.com/S...ob/main/LICENSE

 

The tool is from hobbyists for hobbyists and we do not make any money out of it.

Maybe a bit of background information on the tool: the idea for GraXpert was born by Frank Sackenheim (me) in context of the Dark Matters Discord community about three months ago. The idea was to create an affordable tool for gradient removal, especially targeting beginners. Steffen, Christian, and David picked up the idea and we were able to produce a first release candidate for which we would love to hear your feedback and see your results!

More infos can be found on our website  https://www.graxpert.com that provides both a video introduction (in English and German), a written user manual, and also the possibility to download GraXpert from there.

Do you want to get in contact with us? Please feel free to join the Dark Matters community where we have dedicated channels for GraXpert. Maybe there is a lot of German going on right now. However, generally at Dark Matters we use both English and German so do not hesitate to start a discussion

We hope you like it and we wish you a lot of fun with GraXpert

I've just tried this out and liked it.  I was able to remove a gradient easily which I was having problems getting rid of in Pixinsight.  Good job and great price!

A feature request to think about for the future would be to add support for xisf format.

I don't seem to be able to download an uncorrupted file to linux

Frank,

thanks for the work of you and your colleagues.

triggred by an article in Astronomy Now. I have been trying it out, and it seems to work very well. I have been using it to tame some of those irritating post-processing gradients.

can I add my support to extending file formats to .disfigured.

Should be .xisf format, not .disfigured. Although given how some of my images turn out…

How it started vs how it ended with M31. Naturally, GraXpert was only a part of the process but it did its job well. 

Only GraXpert applied without any further processing on M81 and M82.

Requires a bit of fiddling but overall super easy to use.
Thanks Frank, Steffen, Christian, and David.
Please keep it up.

Hi,

sorry for being late on replying here. Thanks to astronomy now the software came a bit more around in the english speaking community. GraXpert is still under development. We implemented xisf format as well. The software and its algorithms are working very good in my opinion. Dark Ravens results shows its power. Problems that we hear or read often are problems concerning security allerts and problems with installing GraXpert on MacOS. Its very hard for us to get workarounds for this as i think that we need to register GraXpert and this will cost money. I hope that we will be able to release GraXpert 1.0 in the near future and maybe i will invest the money in registration.
