TAKING CARE OF YOUR TELESCOPE
Your telescope is a precision optical instrument designed for a lifetime of rewarding viewing. It will
rarely, if ever, require factory servicing or maintenance. Follow these guidelines to keep your telescope
in the best condition:
Avoid cleaning the telescope’s lenses. A little dust on the front surface of the telescope’s correcting
lens will not cause loss of image quality.
When absolutely necessary, dust on the front lens should be removed with very gentle strokes of a
camel hair brush or blown off with an ear syringe (available at most pharmacies).
Fingerprints and organic materials on the front lens may be removed with a solution of 3 parts
distilled water to 1 part isopropyl alcohol. You may also add 1 drop of biodegradable dishwashing
soap per pint of solution. Use soft, white facial tissues and make short, gentle strokes. Change
tissues often.
CAUTION: Do not use scented or lotioned tissues or damage could result to the optics. DO NOT use
a commercial photographic lens cleaner.
OPTIONAL ACCESSORIES
#928 45° Erecting Prism (1.25 O.D.):
Correctly orients the telescopic image during terrestrial
observing and yields an image position at a 45° angle to the main telescope tube, resulting in a more
comfort-table observing position in most cases.
Additional Eyepieces (1.25" barrel diameter): For higher or lower magnifications with the telescopes
that accommodate 1.25" eyepieces, Meade 4-element Series 4000 Super Plössl eyepieces yield wide
fields of view with excellent edge-of-field corrections and are available in a range of focal lengths
including 6.4, 9.7, 12.4, 15, 20, 26, 32, and 40mm.
#126 Barlow Lens: Doubles the magnification of your eyepieces. For example, if your eyepiece has
36 times magnification, a Barlow gives you a 72 times magnification. Place your Barlow into the
eyepiece holder followed by your eyepiece.
