#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), #776 Hard Carrying Case (for the ETX-105PE) 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 trav- el 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, ETX-90PE, ETX-105PE, and ETX-125PE telescopes 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 ETX-105PE) 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-equipment 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-105PE or ETX-125PE: For extra stability in sensitive applications of the ETX-105PE or the ETX-125PE even at the highest mag- nifications, the fixed height #887 Tripod permits either altazimuth or equatorial orientation of the telescope for astronomical or terrestrial observing. The #887 includes an equatorial wedge for polar alignment. 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 comple- mented by a rubber eyecup (foldable for eyeglass wearers) that shuts out distracting 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 pattern is a dou- ble 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.
