FINDER SCOPES
Introduction To Our Finder Scopes
Finding a specific target in the vastness of the night sky can be a daunting and
frustrating task when the only tool at your disposal is a telescope. To help you hone in on
the celestial wonder you seek, a good finder scope that is properly aligned is a necessity.
Our eight-power 50mm finder scopes are designed to be precision optical instruments in
their own right. Outfitted with a fully multi-coated doublet main lens and a long eye-relief
eyepiece with a precision crosshair or reticle (depending on the model), our finder scopes
provide high resolution, high contrast images at low magnification to effortlessly and
quickly orient your telescope to a particular object or area of the sky. Although they share
a common mission to provide easy guidance, we do offer three distinct models. They are:
Non-Illuminated Straight Finder Scope: This classic reverse-view finder scope has a
simple crosshair that can be centered on your target. It features a front focus with locking
ring and a bright 6° field of view. Illuminated Straight Finder Scope: Explore Scientific’s
original straight-style, correct-image finder scope has a precision-etched illuminated
open circle, crosshair reticle with adjustable deep red LED illumination that makes target
acquisition easy. Precise focus of both the main objective lens and the eyepiece allow for
the sharpest views of the target being viewed as well as the reticle. The finder scope’s
correct-image, right-side-up viewing produces a natural view that benefits astronomy
and terrestrial observers. Polar Illuminated Right-Angle Finder Scope: In addition to
offering a right angle eyepiece for comfortable viewing and a larger 7° field of view, our
top model comes with an illuminated reticle that features northern and southern polar
reference markings for quick and precise polar alignments with any equatorial mount.
Although it has a larger 7° field of view, it shares the same attention to design and
features of the Illuminated Straight Finder Scope. These include adjustable brightness
for the reticle’s deep red illumination, precision focus of both the main objective lens and
the eyepiece and correct-image, right-side-up viewing.
SUN WARNING
DO NOT use a telescope or finder scope to look at or near the Sun! Even momentary
visual contact with the Sun’s light rays can instantly cause irreversible damage to your
eye(s). Eye damage can be painless, so there is no warning to the observer that damage
has occurred until it is too late. Take extra care when using a telescope or a finder scope
during daylight hours, and do not point either at or near the Sun. Do not look through
either when you are moving the instruments during the daytime. Never allow anyone to
use a telescope or a finder scope during the daytime without warning them of the hazards
of aiming either at or near the Sun. Make sure that they are adequately trained on the use
of these instruments before allowing them to start observing. Children should always
have informed and trained adult supervision while observing.
PROPER CARE WARNING
Your finder scope is a precision optical device and keeping the optics free of dust
and dirt is crucial for optimal performance. However, the use of improper cleaning
techniques, tools and/or solutions can cause irreparable damage to your scope. In terms
of solutions, use distilled water and/or an optical glass cleaner that can be found at most
camera stores. Only use pure cotton swabs/balls or white, unscented, lotion-free tissues
for wiping down optics after you have removed as many particles as possible with forced
air or a photographic-grade camel hair brush. DO NOT use optical lens cleaning tissues
