Orion 16" Mount Extension
      #5699506 - 02/25/13 09:46 AM

Just ordered this for my CG5 -- finally grew tired of not being able to observe a 5 degree slice of sky on each side of the meridian due to the RA limits I had to set to keep the scope from hitting the tripod legs.

Hope the thing doesn't make my mount way too heavy. Fingers crossed that it will work out.

My fingers are crossed for you. I did not have a happy experience with my Orion pier extension on a CG5-clone and wood surveyors mount. It made my rig too heavy, cumbersome to carry, and it increased damping times significantly. I sold it. Looks great, though!

I use two of them. One on my CG-5 and one on my Super Polaris. Both mounts have the 2" stainlees leg tripods and the addition of the pier extention have made both mounts more stable.

With the legs retracted my CG4 is solid in this configuration. Yes it is heavier, but there is no more bumping into the tripod legs. It only takes a couple of minutes to remove or re-attach if you find it too heavy all at once.

Sounds like there are some mixed results with this mount extension. At least Orion has a good return policy if I don't like it.

After using the mount extension several times with my CG5 and AR152, I'm sad to say that I found the extension to be unusable at high powers. It does keep the scope from hitting the tripod legs, but it is very unstable. Any little thing such as the hand controller cable moving or the slightest breeze makes the mount shake. It's almost impossible to get a good focus at anything above 100x. The mount is much more stable without the pier extension; at least with the AR152. The problem seems to be that the extension is just too long which creates too much of a moment arm for it to remain steady. Oh well -- live and learn. Maybe the extension works better with a shorter or lighter telescope.

Sorry it didn't work out for you Mike.
Maybe it does have something to do with the extra length and weight. I notice none of your issues with the Omni120 on CG4. Did you have the tripod legs fully retracted? I have never used it any other way.

Yeah, I had the legs fully retracted. I'm going to try it with my Omni XLT 102 on the CG-4. Hopefully it'll prove useful in that role. From your experience, it sounds like that might work out.

I should add that I use an Accufocus which eliminates focusing shakes for me.
Curious to see how your 102 works out.
