7. Suggested Accessories
1/4"-20 Adapter (Orion part #10101)
This accessory bolts to the top of the equatorial head
and provides a threaded post on which to mount a cam-
era or telescope that utilizes a standard 1/4"-20 thread.
Tube Mounting Rings
These quality metal rings are custom-made for use with
the EQ-2 Mount. They are hinged for easy installation
of a telescope tube and are lined with felt to prevent
scratching. Check the outer diameter of your telescope;
if it matches the inner diameter (I.D.) of the rings, then
the rings will fit. If the outer diameter of your telescope
is a little smaller than the I.D. of the rings, that is also
acceptable; you can "shim" the inside of the rings with
extra felt. Two rings are included in each set.
I.D. 3.0": Orion part #7369
I.D. 3.5": Orion part #7370
I.D. 3.9": Orion part #7371
I.D. 4.6": Orion part #7372
I.D. 5.5": Orion part #7373
EQ-2M Motor Drive (Orion part #7827)
This is a small electric motor that attaches to the equa-
torial mount. It turns the gear on the R.A. axis at the
same rate the Earth rotates on its axis, thereby follow-
ing, or "tracking," the apparent motion of the stars.
Automatic tracking keeps objects from drifting out of the
field of view while you're observing, and is required for
astrophotography. Runs on four D-cell batteries.
Extra Counterweight (Orion part #65024)
Required if your telescope does not balance on the
R.A. axis with the supplied 4.8-lb. counterweight. The
additional counterweight weighs 4.8 lbs.
