II
Reflex Sight
#7228
The EZ Finder II Reflex sight makes pointing your telescope
almost as easy as pointing your finger! It’s a non-magnifying
aiming device that superimposes a tiny red dot on the sky,
showing exactly where the telescope is pointed. You keep both
eyes open when looking through the EZ Finder II, which makes
it easy to compare the view through the sight with the wider
naked-eye view. EZ Finder II has a wide 10° field of view, with a
variety of options for attachment to your telescope, as well as
adjustable brightness control.

Installation

To install the EZ Finder II on most
Orion telescopes
For most Orion telescopes, the dovetail mounting bracket will
work best. The EZ Finder II will slip neatly into the dovetail base
that held the telescope’s original finder scope. To attach the
dovetail mounting bracket to the EZ Finder II, loosen the two
thumbscrews on the bottom rail of the EZ Finder II. Slide the EZ
Finder II onto the bracket and tighten the two thumbscrews (See
Figure 1). Then simply slide the dovetail mounting bracket into
the telescope’s dovetail mounting base and tighten the thumb-
screw on the base to secure the mounting bracket.
To install the EZ Finder II on other brands of
telescopes
Use these instructions to mount the EZ Finder II on other
brands of telescopes, custom telescopes, or when you wish to
mount the EZ Finder II in addition to your regular finder scope
on an Orion telescope.
To attach the EZ Finder II, you will need to attach the included
universal mounting base to the telescope. You can attach this by
using the double-sided foam tape (recommended for refractors)
or with the two included screws. In order to attach the universal
mounting base with the screws, you will need to drill holes in the
telescope tube.
To drill the holes in the tube, use the drill template (Figure 2).
Lay the template on the telescope tube so that the long axis is
parallel with the long axis of the optical tube. Poke a pencil point
through the center of each hole, marking its position on the
tube. Remove the template. Use a #25 (.148") or similar drill bit
and drill two holes where the pencil marks are.
Attach the universal mounting base to the tube with the two
screws and secure by threading a lock washer and hex nut onto
the threaded end of the screw. The threaded ends of the screws
should be on the inside of the telescope tube.
Instead of screws, the double-sided foam tape can be used to
attach the universal mounting base to the telescope tube. The
tape is already cut to the correct size. Peel off the backing on
one side, line up the tape to the bottom of the universal mount-
ing base, and press firmly. Then remove the backing from the
other side of the tape and adhere the base to the tube.
To attach the EZ Finder II to the universal mounting base, loos-
en the two thumbscrews on the bottom rail of the EZ Finder II.
Slide the EZ Finder II onto the bracket and tighten the two
thumbscrews.
Alternatively, if you wish to attach the EZ Finder II to your tele-
scope using the included dovetail mounting bracket (getting the
advantage of its higher profile), we offer an optional dovetail
mounting base (#7214, sold separately) designed to work with
the EZ Finder II’s mounting bracket. You will likely need to drill
holes in your telescope tube in order to attach the optional base.
For mounting the EZ Finder II on Schmidt-Cassegrain tele-
scopes, we offer a special bracket (#2330, sold separately) that
