Meade ETX-90RA Catadioptric Telescope Multi-Coated:
Dual use: astronomy and spotting scope. In excellent optical condition, minor cosmetic blemishes. Includes one 9mm Meade Plossal eye piece. Note that it can operate in Alt-Azmuth as well as equatorial mode with RA drive (needs three AA batteries) to follow stars. Modifications: power switch on base allows control of RA motor without using hard-to-reach switch on base plate; plastic tubing replaces focus knob (included) for better accuracy and accessibility; handle on lens cover eases removal/covering. Additions: Sight Mark high quality red dot finder (needs battery); Mead rear cell adapter for prime focus photography; Nikon T connector; 45 deg. amici prismNOTICE: When I went to pack it I discovered the RA motor does not seem to work. I tried putting 4.5 volts across the motor terminals but couldn't detect any noise from the motor. Still, it could be the circuit board or the motor. There are numerous improvements/upgrades to this motor circuit on the internet and the mount still works in equatorial and Alt-Azmuth modes without the motor.
Check out my sales for a Lumix DMC-G3 camera, and another sale for a combination of a Kipon 4/3 camera adapter, ScopeTronix Digi-T adapter and a Meade MA25mm Multicoated lens used with this telescope for eyepiece projection photography.
And on for a 14-42 mm Zoom lens for the camera.
