RE: New Declination Motor

["Gutzwiller, Michael" <mgutzwiller@lanvision.com>]

This sounds fine to me.  For the observation schedule I'm working with now,
reproducible positions are much more important than speed in getting there.

My obervation plan at present is to concentrate at a praticular dec
position.
Unfortuantely my observatory design forces me to park the system (point at
0 degrees elevation and due south) to close the roof.  So repositioning to
the same dec is difficult at present because the mount can move in dec too
easily.

Thanks,

Mike G.

Dan and I did some tests with the new declination motor yesterday.  With 
this high gear ratio motor, the Dec. axis does not move before the clamp 
goes on.  In fact, it does not move except for the slop in the chain drive 
unless you move it.  That is the good news.

The bad news is that it moves a rate of about 1/4 degree per second.  So a 
maximum move might take 6 minutes. Possibly I can speed this up a 
little.  It is in the stamp code.

I think this is OK for me.  I plan to just step back and forth from the 
equator to 7 degrees for a start.  I will probably go 3 degrees at a time 
so that there is an overlap.
