I have created a sheet of basic formulae for Astronomy & Astrophotography & am posting it as a download. They’ve been collected from various sources, mainly around the net and then rewritten in the hope of presenting them simply. This was done as a quick & simple project to help my understanding, but perhaps it will be useful to some others. There are many more related formulae out there, but I’ve just included the basic ones for starters; maybe I’ll do an intermediate collection in the future. Elsewhere you’ll find some excellent spreadsheets & utilities to help with calculations but now you’ll know what’s happening behind the scenes 🙂 Click below to download your file of choice.
