Scott,

Here is some information about Bill Schaefer and his work:

http://www.cerritos.edu/ladkins/Bill...er_project.htm

I'm so glad I ran across your post with the link to the 'Bill Schaefer
Project'!

I was one of the first purchaser's of Bill's large mount (called the AT-120)
when he 'retired' and sold the design(s) to Richard Keenan and Astro-Track
Engineering. I got one of the first few made, when Bill was still 'teaching'
Richard how to make the mounts ... I believe I got the next 12" they made
after Tony Hallas' 12". I still use the mount ... took it out to the field
for almost 20 years in my film days. Now I am using it from my home in
Thousand Oaks, CA. If you like, see my film/ccd web pages.

BTW, do you know of anyone that sells a drive corrector compatible with the
Schaefer mounts? I have a two axis, synchronous motors at 60 hertz, mount.
No stepper or servo motors. My 'Schaefer' model 6665 Digi-Star drive
corrector is not working. It was made by Dave Radosevich in the late
1980's/early 1990's. Or is there anyone out there that could repair such a
corrector?

Anyway, thanks for the link. I have added this link from my ccd
observatory/equipment page.

Martin,

Have you tried to contact Dave? If not I can forward some stuff to him
since I see him on a regular basis.

Not recently. I don't have an email address for him. Seems to me maybe 10 or
so years ago I 'ran across' Dave at some astro function, and asked him about
the corrector. Using it out in the field for so many years had gotten it all
banged up, though it was still working at the time. I seem to remember him
saying he did not have the schematics anymore ... right now I'd be willing
to have anyone repair/refurbish the corrector, as I can't find anyone making
a corrector like this anymore (that SBIG autoguider capable).

Any help would be appreciated,
