I had this problem with one of my ETX's.

My solution was to sacrifice a very small (cheapy) screwdriver. I used a file and sharpened the driver end so it fit the hex hole. With a little twisting pressure on the screwdriver, being careful not to damage anything the hex screw came out.

Well, I tried to get back here and delete my post before someone answered, but for an Old Dog, you're pretty fast.

I solved the problem with a 1/16" titanium drill bit.

Flex focuser is now installed and based on observing a distant neighbor's lamp post, works pretty well.

I believe it will be a good solution to fine focusing and the shakes in general.

In case i ever want to reintall the original knob, where on earth would I find a replacement set screw?

Thanks,

bob

Now my problem is how to get the knob off.

Scoptronix flex focuser arrived today. Supplied hex key does not fit existing focuser knob set screw. No key I have fits. Appears to be stripped. I've never had it off, but the scope was returned to Meade once for repairs.

What to do?



There should have been a little Allen wrench shipped with the ETX. If you can find that, try that.
