I own and use a GSO 2-speed SCT Crayford focuser with my 12" LX200. It screws directly into the SCT visual back. You can then use the focuser in the SCT for your "macro" focus and then just deal with the Crayford for your fine focus.
For $100 (maybe a little less) you could get a new single speed GSO crayford focuser. For ~$130, a dual speed focuser could be had. Both of these options will have 1.5" of focuser travel.
The only warning I have for you is if you utilize a Peterson EyeOpener. I am not sure the EyeOpener is compatible with the SCT Crayford focuser (I have not tried the combination). If you have the EyeOpener, you might have to revert back to the standard visual back.
For clarification, this is strictly for visual use, if that matters.
So I would remove the current electronic micro focuser an put it aside and replace it with one of these?
Is this what you are talking about? I could not find it on Astronmics.
According to the notes at AA:
The 2" focuser barrel features a brass compression ring and can accept standard 2" refractor-type diagonals and other 2" accessories (Note that the use of this focuser converts your telescope's rear SCT thread to a 2" visual back. As a result you will not be able to use an SCT-type diagonal with this focuser; you will need a refractor-type diagonal instead). Also included is a 1.25"-2" adapter with brass compression rings and threads to accept standard 2" filters. This deluxe model features a 360-degree rotatable ring that allows you to orient the focuser (and hence your diagonal/eyepiece) to the most comfortable viewing position.
Please note that some larger Meade and Celestron SCTs (11" and larger) have a larger 3.25" rear thread, so please make sure that you have an adapter that reduces that larger thread to the smaller 2" SCT thread. If you have a standard 1.25" SCT visual back, all you need to do is unscrew the visual back and screw on the SCT Crayford focuser in its place. The focuser is shipped in a foam-fitted box.
So, I would have to replace the diagonal as well, if I read this properly. And likely would need some kind of adapter for the back of the 14" LX200 to make this work. Does that make sense?
I have no experience with SCTs and this looks to be way beyond my $50 budget to enhance someone else's telescope. If I did this, likely I would have to get permission to do the modification.
I don't know what a Peterson eyeopener is or what is does so I doubt it is involved.
