Meade Instruments 5000 ED APO Series - Manual

Introduction
Series 5000 ED APO are true three-element apochromatic
refractors that are virtually free of chromatic aberration (color
fringing), providing pinpoint star images.
A Series 5000 APO is the ideal companion for your larger
Schmidt-Cassegrain, Ritchey-Chrétien, or Newtonian scope.
When piggybacked, a Series 5000 APO is the ideal wide-field
photography scope when guided by the primary instrument and
doubles as a guide scope for the primary telescope. It also makes
an ideal lightweight and portable scope for flawless visual
observing.
Features
• FAST FOCAL RATIO: At f/6 (80mm) and f/7.5 (127mm),
the focal ratio of these scopes is ideal for wide field
astrophotography.
• PREMIUM ED GLASS: Meade uses the finest Japanese
FCD1 ED (Extremely Low Dispersion) glass. This glass is
created to achieve a very small change in refractive index
with different wavelengths of light. This makes it the perfect
choice for a fast, high performance optical design like the
Series 5000 APOs.
• FULLY MULTI-COATED LENSES: Meade broadband
multicoated lenses ensure maximum light transmission.
• TRUE ED APOCHROMATIC TRIPLET: A true triplet
optical design guarantees the textbook color correction you
expect from a premium APO.
• FULLY EXTENDABLE DEW SHIELD/SUN SHADE: An
essential accessory built-in to the design for your
convenience.
• MACHINED ALUMINUM CRAYFORD STYLE FOCUSER:
Superior focuser means smooth and repeatable focusing
with no image shift. Accepts 1.25" & 2" accessories.
• AIR-SPACED OBJECTIVE LENS: The precision air-spaced
triple element ED objective lens focuses red, green, and
blue wavelengths to the exact same point
• ADJUSTABLE LENS CELL: Allows collimation of lenses if
necessary.
• MOUNTING BRACKET: (80mm only): Allows mounting on
a wide verity of Meade and non-Meade German Equatorial
Mounts and almost all photo tripods.
Using the Focuser Assembly
Insert an eyepiece into the focuser assembly and tighten the
focuser thumbscrew.
To focus the eyepiece, turn the focuser wheels in or out. If
you have a 2 inch eyepiece, remove the 1.25" eyepiece
holder from the focuser assembly by loosening holder
thumbscrew. Slide the 2 inch eyepiece into the focuser and
tighten with the eyepiece locking screw.
The focuser has both a lock knob and a tension adjustment
knob. The first lock prevents the draw tube from moving in
and out. The second lock locks the focuser knob, thereby
locking a focus position into place. Experiment with these
knobs to discover which adjustments are comfortable with
your viewing style.
