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! -

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 -

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 -
