Hi Ned

It's a Feathertouch focuser (or any other brand) that's installed outside the OTA. Use it instead of the 'inside' focuser.

Using one like that you can set the OTA focuser somewhere in the middle, and use the outside focuser to control focus. Then, once collimated, you shouldn't have to do that again because you never 'bother' the tube for anything.

Wish you luck.

Steve

What is an "outside focuser"?

I use an RC with an outside focuser and CCD Inspector - easy to collimate, and very very very accurate - and since focus outside means it stays in collimation forever - unless I move it.
