Peterson EZ Focus Kit for Meade 6" - 12" Schmidt- & Maksutov-Cassegrain Telescopes
Peterson Engineering EZ Focus Kit
This kit is intended for use with all Meade 6" through 12" Schmidt-Cassegrain & Maksutov-Cassegrain telescopes, including the LX200ACF/GPS/R, the LX90, the 6" and 8" LX80, LightSwitch and LT series scopes, the LX200 Classic, the LX50, LX10, and even the original 2080. The kit removes most of the backlash in Meade's focusing system and consistently provides a light precise feel to the focuser knob. The EZ Focus Kit does not work with the 14" & 16" models due to major design differences.
The EZ Focusƒ??????????’?????????? Kit is used to modify the Meade focus system - it does not replace it. By substituting precision thrust bearings for the existing nylon washers, this kit greatly reduces the need for separate costly, bulky backplate-mounted focusers and motorized focus controls. (Or in the case of the LX200GPS, the need to waste time in switching over to using Meade's Microfocuser.)
The procedure is simple, and the instruction sheet contains detailed step by step instructions, accompanied by pictures. The only tool you need supply is a simple pair of pliers.
This extremely effective approach to improving focuser action was developed by Michael Hart. Mr. Hart's basic design is posted in the MAPUG archives. The EZ Focusƒ??????????’?????????? Kit significantly improves on the basic design and modification procedure. In addition to the very detailed instructions and step by step photographs that anyone can follow, the kit contains a collection of difficult to obtain items - 2 precision miniature thrust bearings, a custom stamped stainless steel thrust washer, an Allen wrench, a mirror cell retaining bolt, and a packet of the same grease used by Meade for lubricating all of the telescope's internal workings.

Excellent kit with clear instructions
Despite having a technical background, I think the instructions with this kit would be easy enough to follow for astronomers without such a background. Clear instructions with pictures. Ultimately the focusing **** is now a lot smoother!
LX200ACF-12. Installation instructions are very good and cover many different models. You could have problems installing this because Meade dimensions very between scopes. I ran into problems with my focus knob set screw hitting the brass threads. After some tweaking, I was successful. It's not the fault of Pete, he cannot account for scope manufacturer quality of dimension control. In the end you still have back lash in the focus screw and pin that the focus slides over, this kit does eliminate the Nylon washers and back lash associated with them. So, it will reduce one area of play. I question if it's worth installing since it only eliminates a small portion of play in one of several areas. It is relatively inexpensive. I gave it 4.5 stars because it is and inexpensive improvement that DOES eliminate some play and has excellent instructions.
