Re: [ATM] Converting ALT and AZ to RA and DEC

["Martin Cibulski" <martin.cibulski@t-online.de>]

Hello,

for coordinate transformation I found a document written by Toshimi Taki 
very useful.
It shows the AltAz/RaDec transformations and some more.

Here is his homepage:
http://www.asahi-net.or.jp/~zs3t-tk/
On the left menu select
'Matrix Method for Coordinates Transformation'

Regards,
Martin Cibulski
