[ATM] Putting digital setting circles on a massive existing mount

[Guy Brandenburg <gfbrandenburg@yahoo.com>]

I know of a 14" Schmidt-Cassegrain telescope on a very
large, old Ealing mount. It has simple analog setting
circles. I have an interest in  installing digital
setting circles on it, so it is no longer necessary to
star hop. Because of the way the mount was built, it
is not possible to 'reach' the axes of the mount to
install typical encoders. I was wondering whether it
might be possible to install encoders on the OUTSIDE
of the telescope mount... Any thoughts?
