Any astronomers out there? I'm wondering if anyone has produced or stumbled upon a .NET (preferably C#) implementation of the US Naval Observatoru Vector Astrometry Subroutines (NOVAS).
I know nothing (of consequence) about astronomy, and absolutely nothing about NOVAS, so please take this with a grain of salt.
But, I did look at the website, and it looks like they have a C implementation. You could always take the C implementation, access it via pinvoke, and write a C# wrapper around it.
