Hi everyone,
I’m looking at building a new setting based around near Earth stars, and was hoping that someone may be able to help advising me how to convert Right Ascension and Declination into X, Y, Z Cartesian co-ordinates?
So far, I’ve found methodology here;

…but was hoping someone might know of an online calculator, or a spreadsheet they could share for doing this, to save the heavy maths.
Many thanks
