At some point you have to stop and
reset the screw or you risk tipping over
your telescope. You can double your
tracking time by raising the west side of
your mount by that same height, starting out low on the east side and tracking through level to high. Art reports
that "With the 30-inch spacing on my
tripod feet I get about ﬁve minutes of
tracking for each inch of travel turning
If you start an inch low and go until
you're an inch high, that's ten minutes
- plenty of time for most observations.
It's a great improvement over no tracking at all. And that's the name of the
game when it comes to ATM projects:
Art says, "I've been pushing Dobsonians around for decades and wish I'd
thought of this long ago."
