Hi John
I've always used 1 9/16" (1.5625") and never had an issue.
Hope this helps

Hello Bob
If you go to the classified section and the advanced search box to the upper right, you can get some idea. A quick search came up with between about $4800 to $5500 depending on included items.
Hope this helps

Where do you get your trusses from?

Hello Lawrence
I've purchased from Online Metals many times for various projects. They have many different types of metals and different shapes available.

Lightweight AND wide field binos? Orion Scenix and?

Posted By Bernard Kean
Check out the Garrett® Classic 8x42 DCF-TWP Triplet Phase-Coated Binocular. They are roof prisum and only 680g with 6.8° fov. They are some of the sharpest binos I've ever used for astronomical use and close focus is around 10 feet so are excellent for terrestrial as well.

Feeding a Losmandy G-11

The 12v 30amp power supply should be fine under normal use. IIRC the issues crop up with weak batteries, very cold temps, or under heavy load with guide scopes, cameras etc. It also helps to set the fast slew speed down a bit and make sure the balance is good. The motors take the most strain while trying to ramp up to slew so all these factors come into play.

I wouldn't worry too much about it as long as it blows off with a bulb blower. I would worry about it if it continues to shed fuzz.

My EM 200 thinks is in Austalia

Posted By Bernard Kean
If there is an internal battery in it try changing it. I have seen the small memory circuits "forget" settings because the coin type battery that powers it has lost its power. I have heard of low power in the internal battery cause a variety of different issues because it looses different bits of memory settings. Usually a stored setting reverts back to a default (or sometimes something totally different).
Hope this helps

Airline Portable DOBs

Posted By Bernard Kean
Hi Jim
While I have never owned a UTI and I am not exactly sure why they quite production, I suspect it is because of they were quit expensive. IIRC the UTI6" was in the neighborhood of $2K with the UTI8" considerably more. The market would be pretty small for those willing to pay that much for airline portablity alone when an import 6" dob is still easily portable in anything except airplanes and vastly less expensive.
Just my $.02

Telepod Azimuth Bearing is frozen

Posted By Bernard Kean
The set screw securing the 3/8" mount screw should be tight. If you unscrew the cap on the top of the bearing you will find 3 small set screws that are used to adjust the tension of the AZ bearing. Loosen these set screws and adjust the upper and lower halves so they rotate but no slop then tighten the 3 set screws to lock the halves. It will take a bit messing around with this adjustment to get the desired tension without rocking between the halves.
Hope this helps.
