ETX90 RA in very good condition with excellent, clean optics. I am the original owner and purchased this in May 2002. It comes with the original instructions, and MA 25mm and MA 9 mm eps which originally came with it. I have also added the following accessories:
Meade 8x25mm right angle finder
red dot finder
Meade thread in dew shield
Scopetronics 1 1/4" visual back
I have used this OTA separately from the mount as a spoting scope, on a camera tripod with a Scopetronics Digi-T for my digital camera with very good results.
I have over $350 in this. I will sell for $175 plus shipping.
Full disclosure: I glued a small piece of aluminum on the OTA in order to mount the red dot finder. Also, if you cross thread the dew shield, it is possible to unthread the front cell from the OTA.
