RE: AlfaSpid Az/El users



Daniel -- you might want to take a look at the MIT Haystack 
Observatory's Student Radio Telescope (SRT) pages at 
http://web.haystack.mit.edu/SRT/index.html. The ALFA/SPID is one of two 
options they recommend for the project. You might also find their users 
forum (http://web.haystack.mit.edu/SRT/forums/) to be of some use in 
finding others who can help.

To use the mount as a telescope, Alan Rogers has designed a new rotor 
controller using a Basic Stamp BS2 and National LMD18200 "H-Bridge" 
motor controllers (see 
http://web.haystack.mit.edu/SRT/pics/schemgndctl.pdf).

In addition to the Alfa/Spid, a nice heavy duty az/el mount is also 
available from CASSI (http://www.cassicorp.com/)

73, Tom
