The modular design of the CF refractor focuser makes it very versatile for just about any refractor. Just pick the options you need in these 4 categories: Flange, Drawtube, Focus knob/motor, and Color.

We offer everything from single rate drive configurations to our popular dual rate 8 to 1 Tri-knob reduction unit for heavy duty loads such as (CCD imagers and bino viewers). We offer several different types of motor systems and PC based interfaces providing automated focus ability running today's ASCOM software. Plus different draw tube travels and configurations for every kind of EP, Bino viewer and CCD camera. Our collimatable mounting flanges provide flexibility for achieving perfect mechanical centerline collimation. Our shaft lock option provides focus lock with no image shift. Custom anodized colors and custom machining (by request) make for a perfect custom focuser to match your refractor.

Flanges:

MoonLite manufactures over a dozen standard sizes of flanges that fit many different refractors, plus we do 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.

The flange bolts on to the focuser body with 3 bolts and acts as an interface between the refractor's OTA and the main focuser body. The thickness and diameter of the flange is designed for the telescope it is to be installed on. The smooth bore type flanges all have collimation ability using a simple 3-point push pull bolt/setscrew arraignment. The threaded style flanges do not provide collimation ability. 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. All flanges below have a rotating ability with lock knob providing camera angle adjustment.

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

Draw tubes:

MoonLite offers 5 different drawtube configurations for the 2" format CF model refractor focusers. Please use the pull down menu to select the drawtube located at the bottom of this page. Please Note - All focusers include a 2" to 1 1/4" adapter. The adapter is threaded for 2" filters!

• Regular 4.5" travel drawtube that uses an aluminum thumbscrew (non compression ring style). The standard drawtube is a good choice for lightweight loads and has the lowest profile of all of the drawtube options. It comes with an 1 1/4"adapter.

• 4.5" travel drawtube with a 3 knob brass comp ring configuration version comes with a 1 1/4" comp ring adapter threaded for 2" filters. The brass compression ring drawtube option is a good choice if heavy loads are used in the focuser or off axis loads such as bino viewers that place torque on the focuser drawtube. The 3 thumbscrew configuration can hold a huge amount of weight. The bump out section on the top of the drawtube adds 3/8" to the height of the focuser, but the extra height is not an issue on refractor focusers.

• 2.5" short travel version drawtube is designed for fast F5 scopes. The shorter length of the drawtube keeps the edge of the drawtube from bumping the light cone when racked the whole way in on Fast refractors.

• 4.5" travel "low position" compression ring style drawtube. This drawtube also uses 3 thumbscrews for extreme grip like the models above but the brass compression ring is located in a lower position so the brass compression ring clamps around the true 2" OD of diagonal, not at the beveled under cut area. Some Diagonals such as AP and WO brands have bevels back cut in to the 2" OD barrel. MoonLite's "Low position" drawtube solves the misalignment problem and grips the diagonal properly to maintain accurate collimation and load bearing ability. Please note- the "low position" comp ring bump out on the top of the drawtube adds .8" to the height of the focuser, not 3/8" like the regular comp ring design does.

• 2.5" travel "Low position" compression ring style drawtube is designed for fast F5 scopes. The shorter length of the drawtube keeps the edge of the drawtube from bumping the light cone when racked the whole way in on Fast refractors. It also offer a Low Position brass compression ring location like the 4.5" travel drawtube above.

Please consider Moonlite's T-thread adapter for attaching your CCD / Filter wheel to a MoonLite focuser.If fixes the mis-match size problem between the 2" compression ring drawtube standard and the under cut section (1.9") nose piece. It makes for a very rigid and collimated solution when clamping on to a true 2" smooth bore surface.

Focus:

MoonLite has many knob and motor configurations. Our reduction systems and motor options are integrated into the focuser at the time of assembly. It is important topick the correct configuration at the time of purchase as adding options, "such as a motor" requires sending the focuser to us for the upgrade. Please use the pull downmenu located at the bottom of this page to select the configuration you need.

• The Single rate configuration uses 2 regular 1.5" diameter knobs providing .58" travel rate per revolution. The single rate configuration is only recommended for light weight duty due to the 3 lb vertical load capacity. Almost all MoonLite focusers are dual rate Tri-knob or motorized versions, however we do offer this single rate model for smaller scopes that are not using heavy loads and do not need a 2 speed reduction unit.

• The dual rate Tri-knob option is a 2-speed configuration with a regular knob on one side and a fine and coarse knob on the other. Both coarse knobs are 1.5" OD, and the fine knob is 1.2" in size. The fine knob uses an oversized 8 to 1 reduction unit featuring a preloaded, all ball bearing planetary reduction design that has no backlash or play. The inline unit can simple be rolled by the slightest touch of your finger to make very fine focus movements plus has an auto brake when focus is stopped. No scope wiggles here and perfect collimation plus an 6 lb weight capacity make this option ideal for typical visual or imaging use. The fine knob is on the right by default, but can be made a lefty if needed. If increased lifting capacity is needed, please consider one of our motor options below. The motor option give the CF focuser an 8 lb lifting capacity rating.

• The dual rate Tri-knob with Shaft Lock option also uses the 8 to 1 reduction unit like above but adds a Shaft Lock knob on the standard side. The Shaft lock option uses a unique mini brass compression ring clamp sub system that allows the user to lock the shaft with out deflecting the drawtube. This type of focus lock is much better then the old "thumb screw against the draw tube" style that would shift the image when pressed against the draw tube. The fine knob is on the right by default, but can be made a lefty if needed.

• The DC servo motor option provides fully adjustable speed control using the best hand controller on the market today. Rigel Systems battery operated multi speed controller along with our DC gear head motor system make a great combination for visual or imaging use. All motor options give the CF model focuser a n 8 lb lifting capacity. See motor link below for additional information.

• The High Resolution Stepper motor - "Stand alone option" provides extremely fine focus resolution required by today's high-end CCD imaging platforms. It provides a 8 lb load capacity once installed on a CF focuser. It gives the focuser great repeatability and automated focus ability for today's imaging requirements. The High Res Stepper motor features a rotatable mounting bracket, and a 9pin DBA standard pin out so it will work with ROBO focus controllers. It is Pin for Pin compatible with Robo focus controller. However we offer 2 different controllers in the next selection if you do not have an existing controller available. See Motor Focus link below for more information. Stand alone stepper motor option $190 (you provide the controller).

• The High Res Stepper motor with MoonLite mini controller includes a bare bones ASCOM Compliant Controller along with the Stepper motor. The MoonLite mini controller features temp compensation and all features of our high end controller, but does not have the Display or Manual buttons. You must use a PC to operate the stepper motor with this mini controller. It uses a USB connection to your PC and runs of standard 12 volt DC. We include a AC adadpter with all of the universal plugs so it will work in any country. The 8 lb load rating and precise focus ability make this a good configuration for permanent or remote imaging platforms. The lower cost of the controller $195 makes this a good pick if no manual buttons or display near the scope is needed. The stepper motor with mini controller option cost only $385. See Motor Focus link below for more information.

• High Resolution Stepper motor with MoonLite 2-speed DRO display controller is a high end fully ASCOM Compliant option. This new moonlite controller is best for both Visual and PC operation due to its 2 speed buttons and full DRO display. It has a fine and fast set of buttons with a full DRO position read out on the display that shows the exact step count position just like in the software of your favorite imaging program. The controller has temp compensation, digital display for temp, position, voltage, operating modes, etc, plus manual buttons for stand alone use. This controller also offers both Serial and USB connectivity to your PC (will auto sense). The 8 lb load rating and extreme precise focus ability at .00008" resolution and repeatability make this the ultimate configuration for permanent or remote imaging platforms. This controller/ stepper motor option is recommended for both PC and hand held manual operation due to the controllers design. Comes with universal AC adapter and USB cable. See link below for more information on this new controller. Has built in Support for Moonlite's optional flange rotation feature coming soon. The controller also has built in Blue tooth wireless remote support coming later this year. $685 for the Stepper motor and MoonLite MoonLite 2-speed DRO display controller option.
