The Meade #497 Autostar Computer Controller turns the ETX-90EC, ETX-105EC, or ETX-125EC into an automatic celestial object locating system. Just plug the Autostar into the telescope’s HBX port in place of the standard-equipment Electronic Controller, do a quick (less than one minute!) telescope alignment, and you’re ready to observe any object in the Autostar’s 30,000-object database.
Meade Series 4000 eyepieces yield the widest possible fields of view, consistent with pinpoint edge-of-field sharpness and long eye relief-and yet with extremely low astigmatism, spherical aberration, and off-axis colour. Incorporating 7-layer multi-coatings and edge-blackened optics for optimum image contrast, these sophisticated 4 to 8-element designs permit levels of optical performance generally impossible to achieve with eyepieces of fewer e

For terrestrial observing with the ETX-60AT, ETX-70AT, Astro Telescopes the 45? Erecting Prism attaches to the telescope’s rear cell and presents correctly-oriented images, viewed at a convenient 45? angle. Also shown in this photo are the Declination lock, focuser knob, and flip-mirror knob.Note: Image for illustration, accessory only.
