I use an equatorially-mounted Newtonian, and inititially had problems
tracking satellites, but I got used to it.  What helped a great deal was to
point the polar axis straight up, instead of at Polaris.  This way
I had a azimuth axis and an elevation axis that were much easier to
control.  Give it a try and see if that helps.

I used a MSDOS QBASIC program called POLE for a time that would calculate
where to align the polar axis so you could just track along the RA
axis, but stopped using it once I got more adept at hand-tracking.
POLE.ZIP is at:

I don't know the author's name.

It requires Mike McCant's quicksat program in order to work.  Quicksat
and other prediction programs are at:

The specific link for the MSDOS version of Quicksat is:
