STAR-FINDER RINGS
To mount the star-finder on your main telescope you need a bracket
of some sort. The bracket needs to be adjustable so that you can
line-up the star-finder with the main telescope. A pair of star-finder
rings provide one way to solve this problem. Each of the rings has
three clamp screws to cradle the star-finder. By adjusting these
clamp screws, the position of the star-finder within the rings can
be altered until it points in just the right direction.

A pair of finder rings on a support bar.
This consists of two metal rings with an internal diameter of about
3”. The rings are mounted, one behind the other, about 4”
apart, on a sturdy rectangular aluminium bar. The aluminium bar
can be bolted to your main telescope by means of two holes, set
2” apart. This set of star-finder rings is painted in satin
black to contrast with our brass star-finders.

A
pair of brass finder rings
Each ring is mounted on a pillar that is provided with a 'foot'
by which the ring is bolted to your telescope. Each of the six adjustment
screws is provided with a soft-lined pressure pad (not shown) to
cradle the finder telescope, so that it is not damaged when the
adjustment screws are tightened.
We recommend these luxurious brass rings whenever appearance and
quality are of the essence.

We acquired a quantity of star-finder brackets that we think were
made by Charles Frank, of Glasgow, many years ago.
The bracket consists of a cast aluminium base, 7” long, 2”
wide and ¼” thick, with a semi-circular cradle at the
front end to support a telescope of about 2” diameter.
The idea was that the star-finder was held at the front of the
bracket by resting it in the cradle and securing it with a long
coiled spring that passed over the finderscope. At the rear, the
star-finder was secured in the ring by the three adjusting screws.
Some of these brackets are the bare alloy casting, others have been
painted black.
The brackets we have in stock do not have the spring. You can buy
these extension springs from a good engineering supplier or you
can just use a strong elastic band instead. If one of these brackets
would suit a star-finder of yours, we’ll sell it to you ever
so cheaply!
