Moonlite Product Info

The modular design of the CFL large 2.5" large format refractor focuser makes it very versatile. Now fitten with Moonlite High Resolution Stepper Motor Kit with Mini Controller V2.

We offer everything from our heavy duty tri-knob reduction unit with shaft lock system to different types of motor options for both visual or imaging configurations. Our "High Res" stepper motor options use PC based interfaces, providing automated focus ability running todays ASCOM software. Different draw tube travels and configurations are availible. Our collimatable mounting flanges provide flexibility for achieving perfect mechanical centerline collimation should the need arise. Custom anodized colors and custom flange machining (by request) make for a perfect custom focuser to match your refractor.

MoonLite manufactures many flanges that fit a variety of different refractors, plus we machine custom flanges for any size telescope by request. Please use the pull down menu to select the flange located at the bottom of this page.

All CFL 2.5" large format focuser flanges feature a 2 piece rotating flange design with a lock knob providing camera angle adjustment. It consist of an upper flange part and a lower flange part on a rotatable radial dove tail design. The upper flange part bolts on to the focuser body with 3 bolts and contains the twin dove tail finders. The lower flange part has the threads/ bolt pattern that matches the refractors OTA and connects in to the upper flange. The thickness and diameter of the lower flange is designed for the telescope it is to be installed on. This 2 part rotating flange system provides collimation ability using a simple 3-point push pull bolt/setscrew arraignment. Please note all focusers are factory collimated dead on before we ship them, and do not require any adjustment. The only time collimation should be changed is if the OTA has some kind of defect causing the focuser to set slanted on the tube. In this case the focuser's collimation ability would come in handy to correct the mechanical centerline collimation of the OTA in question. Flanges can be swapped on the bottom of the focuser so it will fit different refractor. Extra CFL Flanges are sold separately for $95.


The WO 132 FLT flange fits the large WO 132 FLT OTA. It is a female 5.435" by 1mm threaded flange. The correct drawtube is the 4.5" travel size. A free 2.5" thick flange extender is included with this focuser.


Custom Flanges -Moonlite can machine a custom flange to fit your OTA. We can machine flanges from 4" to 9" in diameter. Machining normally takes a few weeks. Please contact us for a quote and anticipated turnaround time.

The profile of the CFL focuser depends on the flange installed. The flange thickness is designed to make the CFL focuser mimic the focusers profile it is to replace.

Lifting Capacity: The drawtube pressure can be adjusted to each user’s preference. Increasing the pressure increases the load capacity (vertical lifting capacity) of the focuser. Decreasing the pressure lowers the load capacity but gives the focuser a smoother focusing action. We set the focuser at approximately 6 lbs. at time of assembly; however, you can adjust it to be less or more depending on your specific needs. The ideal setting is to have it adjusted so the focuser can hold the heaviest load presented without slipping and requiring no additional force. This will give the focuser the best feel and still provide the vertical lifting capacity required.
To adjust - turn the aluminum thumbscrew located between the two setscrews on the bottom of the focuser CW to increase load capacity. The aluminum thumbscrew can only add pressure, not take away pressure. This is due to the 2 setscrews on each side of the thumbscrew applying a minimum set pressure amount. In some rare cases, it may be necessary to do a coarse adjustment by turning the 2 setscrews located on each side of the aluminum thumbscrew (1/8 allen wrench) a very small amount. Normally, 1/20 of a turn or less should be made on the setscrews in a CW direction, then check the lifting capacity pressure by racking the drawtube up and down.


Collimation: CFL focusers have 2 collimation systems. The traditional upper to lower flange tip/ tilt collimation system using 4 small set screws, and also the new C-axis collimation at the bearing locations for drawtube collimation. To adjust flange collimation, turn the 4 mini setscrews located in the top part of the 2-part flange. A small amount of tip/tilt (.015 max) can be made between the flanges by adjusting the setscrews. We collimate the C-axis drawtube's center line before shipping it so no adjustment should be required. See video on how the new C-axis collimation is performed as it can be changed by the user if needed.
