Hello All,(adsbygoogle = window.adsbygoogle || []).push({});

Noobie question. I am using Meeus' Astronomical Algorithims to creat a spreadsheet to transform coordinates. I had no problem with precession, nutation, aberration, etc. But, I don't have as good a math background for Motion in Space.

I can follow down to the final formulas for x', y' z'.

I researched further and found Meeus' source in the Sky Catalogue 2000.0 and that really didn't help me either.

I just don't have the math background.

Can anyone expound on what I do AFTER I solve for x', y' and z'?

Any help greatly appreciated.

Thanks, Scott

P.S. I added a zip of a bmp of the relevent page in the Sky Catalogue.

In any explaination, please keep my genetic deficit in mathematics in mind.
