#932 45° Erecting Prism: All ETX models include an internal optically-flat mirror to
reflect light to the telescope’s 90° astronomical observing position. In this position the
telescope’s image is upright, but reversed. For terrestrial observing with an ETX
model, the #932 Erecting Prism (Fig. 38) correctly orients the eyepiece image and
provides a convenient 45° observing angle.

#774 Hard Carrying Case (for the ETX-90PE) and #775 Hard Carrying Case (for the
ETX-125PE): For secure portability of ETX Astro Telescope models in the field, Meade
hard carrying cases (Fig. 39) are fully lined with fitted foam inserts. They accept the
complete ETX Astro Telescope plus optional accessories.

#765 Soft Carry Bag: The Meade soft-padded carry bag (Fig. 40) is well suited to
travel with the ETX-90PE Astro Telescope. Each carry bag includes a shoulder strap
and permits ready transport of the complete telescope, including accessories.

Power Adapters and Cords: In addition to their internal battery packs, the ETX-
125PE telescope may be powered from standard 115vAC home electricity with the
#541 AC Adapter. The #541 plugs into any standard home outlet and includes a 25
ft. cord connecting to the telescope’s control panel. Input voltage to the telescope is
12vDC. Alternately, an ETX telescope may be powered in the field from an automobile
cigarette lighter plug by using the #607 Power Cord, a 25-ft. cord that plugs into the
telescope’s control panel and supplies 12vDC directly from the car battery.

#1244 Electric Focuser (for the ETX-90PE) and #1247 Electric Focuser (ETX-
125PE): Meade-engineered for smooth, rapid focusing with any ETX model, each
electric focuser (Fig. 41) includes coarse and micro-fine speeds. The standard-equip-
ment hand controller accepts one (user-supplied) 9-volt battery and focuses the ETX
telescope. On the ETX models, the focuser plugs into and is
powered by, the telescope’s control panel, with operation effected through either the
AutoStar or the optional #497 AutoStar Computer Controller.

#887 Advanced Field Tripod for the ETX-125PE: For extra stability in sensitive appli-
cations of the ETX-125PE even at the highest magnifications, the fixed height #887
Tripod permits either altazimuth or equatorial orientation of the telescope for astro-
nomical or terrestrial observing. The #887 includes an equatorial wedge for polar align-
ment. The tripod's 2"-diameter steel legs collapse for easy transport in the field.

Series 4000 Plössl 9mm Illuminated Reticle Eyepiece: The most advanced com-
mercially-available illuminated reticle eyepiece, this Series 4000 Plössl 9mm model,
powered by an internal battery, includes micrometric x-y positioning controls which
greatly facilitate locking onto the guide star: Turn the finely-threaded controls and
place the reticle’s crossline pattern precisely at the desired position in the field. The
sharp, high-power imaging of the 4-element, multi-coated Plössl optical system is
complemented by a rubber eyecup (foldable for eyeglass wearers) that shuts out dis-
tracting stray light from the observer’s eye. The upper (lens) section of the eyepiece
rotates on a fine thread for precise diopter adjustment to the user’s eye. Reticle pat-
tern is a double crossline with two concentric circles.

Deep Sky Imager: This high-performance, easy-to-use and affordable color CCD
camera (Fig. 42) suppresses electronic noise and does not compress data from the
sensor to increase picture quality. The Deep Sky Imager uses a full 16-bit analog-to-
digital converter to enhance picture depth, contrast and dynamic range. It is USB com-
patible for easy interface with most Windows-based laptop computers. Includes
AutoStar Suite which automatically sorts, aligns and combines the best images, result-
ing in a highly detailed color image.

Atomic Time Update Module: For use with all Meade ETX Premier Edition
telescopes, this optional accessory allows you update the LNT Module with the time
signal from the NIST atomic clock in Fort Collins, Colorado.
