Meade ETX-90 Premium Edition ota with caps extremely clean
Have here a lovely 2007 Meade ETX-90 PE (Premier Edition) optical tube. This will come with the original front aluminum dust lid, rear aluminum dust lid for straight through port, and an aftermarket dust plug for the top diagonal port.
It should be noted this will also come with ALL the original side bolts for mounting to a fork. So this is ready to fit to ANY EXT-90 fork arm assembly of any years.

Optics: Ultra High Transmission Coatings (Premium Multicoatings)
Barrel size: 1.25-inch
Materials: milled aluminum, steel, polyvinyl plastics, optical glass
Total tube length: 10.95-inches
Main tube diameter: 4.10-inches
Weight: 2 pounds 13 ounces
This lovely mak has a stock underside plate with (2) #1/4-20 holes that will let it mount to any applicable tripod pan head. The PE is the highest grade ever offered in the ETX mak lineup and I have never ever come across a poor optics example. Side by side I have yet to find an equal-sized ETX that will best it, and much to my own dismay as a Celestron fanatic, NO C90 can compete with this model.
Like other ETX maks and their copiers (yes Meade copied Questar to a much lower extent), these have a flip mirror where you can view at 90-deg or straight through. You can thread on a 45-deg diagonal and then view correct image.
The Orion Nebula image on the aluminum body is only seen on the PE tubes. I LOVE this scope for lazy, suburban pursuits of Venus, the Moon, Jupiter, Saturn, Mars, and the big dsos like M42, M8, M22, M13, and M31.
Cosmetics are very excellent. Flip mirror and focuser are perfect. No dents or scratches. I think collimation is perfect right now. Optics are mint on the primary and corrector and very excellent on the secondary. Spots you see on the primary are merely reflections of my drop ceiling tiles. They are not on the mirror.
Happy to ship to anyone anywhere.
