Hi All,

 

Are your arms too short?  Not able to adjust the tuner while looking through the eyepiece?  Well we have a solution for you!  Add one of our DC motors and nFOCUS motor controller to extend your grasp!

 

We've done a couple of these, for th 60mm and 100mm etalons (see photo for the 100mm etalon) just a simple collar with bracket for dC motor with rubber wheel to rotate the etalon tuner thumbwheel.

 

And it's affordable -- just contact us to see how affordable (<<< than the cost of the etalon !!!!!) But saves you time, aggravation.  So if you're interested send us a photo of your etalon and we'll just ask for a few simple measurements for the collar and proceed from there.

 

These are the improved versions,  we've done a couple of early ones, but this is the approach we like the best! Do note the second photo as to how far it is from the eyepiece to the etalon!  Can you stretch that far?

 

thank you

They do work very well , now I don’t have to catch my wife to adjust the front etalon.

Leon forgot to mention they are two speed, fast will get you close and then slow it down and dial it in to where you need to be.
