CollimationCircles
Collimation Circles, app for easy telescope collimation
This program was inspired by Mire De Collimation program written by Gilbert Grillot and Al's Collimation Aid. I combined best features of both and addes some of my own. Purpose of this program is not to reinvent the wheel, but rather to learn new technologies, become better at colimating my telescope and to learn something new. Main purpose of this program is to help you with aligning optical elements of your telescope such as secondary mirror, primary mirror, focuser, etc. Collimation Circles is developed with .NET 7 and AvaloniaUI Framework using MVVM architecture patern. Program was tested on Windows 10 and 11, Ununtu Linux 22.04.1 LTS (Wayland) and Raspberry PI OS Bullseye. I'm not able to test it on macOS, but it should work. Suggestions and contributions are welcome! -

PGMania
Astrophotography image & video processor. Full processing cycle
PGMania is a universal package for processing deep space images. The program provides wide and unique functionality, a powerful and flexible tool with a clear and user-friendly interface. The program performs all image processing cycles for astrophotography, including filtering, cleaning, aligning, image calibrating, stacking, post-processing, format conversion, cropping, rotations, many special operations and much more. PGMania is environmentally friendly - it does not clutter your photos with something that was never there. You get full control over all processing processes and the most clean and accurate result at all cycles. The program has a clear and user-friendly interface and detailed help for all stages of processing. -

Dark Master - Fork
Fork of Dark Master and allows astrophotographers to match dark frames
This is a fork of the longer unmaintained Project "Dark Master" which still can be found here: https://sourceforge.net/projects/darkmaster/ Dark Master allows astrophotographers to quickly match dark frames to light frames based on temperature. The inputs to Dark Master are the directories to the light images and dark images. The output is a DeepSkyStacker file list. Updates for the fork: - Sorting of files: Via a pattern you can determine, how the groups and images processed by DarkMaster are saved in a directory. This allows to quickly build a library out of unsorted Darks, that also contains sensor temp information. - Fixes for exposure times <1s, which lead to exceptions in DarkMaster v1.15 -

Gravity Simulator
2D Gravity simulator, including a simulation of the solar system
This application started out as a study of Newtonian physics, but evolved into a 2D simulation of the solar system. (Viewed from the south, because Jupiter just wouldn't be Jupiter without the great red spot.) The source code is available for developers who would like to make their own customizations and unique scenarios - like sending a black hole through the solar system. For the casual user, this program allows you to truly become familiar with the solar system. Flying a space ship with unlimited fuel, lots of dials to guide you to your destination, and one less dimension to worry about, you can experience the vast distances, enormous speeds and tremendous power of gravity first hand as you travel around the solar system. Yet you will find that space travel still require great skill and patience to master. However, it will also give you the context to understand these huge numbers when you read about space stories in the newspapers. A great tool to get kids interested in space too. -

swenglal
.Net library for using Swiss Ephemeris library swedll32
Swiss Ephemeris .Net Gateway Library for AstroLight (Swenglal) is a low-level .Net library meant to provide an easy access to Swiss Ephemeris official library (swedll32.dll) in .Net projects. It also contains some handy .Net methods providing a low level abstraction layer for a convenient use of swedll32. This means that this software CAN NOT BE USED WITHOUT Swiss Ephemeris library (swedll32.dll) nor without Swiss Ephemeris files. Note that Swiss Ephemeris is developped and supported by Astrodienst and distributed under GNU Public Licence (GPL) and SEPL (Swiss Ephemeris Public Licence). Swenglal is a TOTALLY INDEPENDANT LIBRARY developped and supported by Margot Honoré with absolutely no relation to Astrodienst or Swiss Ephemeris. Just put swedll32.dll in the same directory that swenglal's and enjoy swedll32 functions and more in your .Net project ! Have fun ! Margot Honoré -
