This adapter provides the standard male T- thread and fits into any focuser's 2" draw tube. Great for connecting CCD / Filter wheel set ups to your focuser, plus the bottom of the adapter is threaded for 2" filters.

The modular design of the CS focuser makes it very versatile for any SCT. 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 standard dual rate 8 to 1 heavy duty tri-knob reduction unit for heavy loads (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. We offer a new special flange/ drawtube configuration that holds a focal reducer inside the focuser for the ultimate image/focuser platform. Our shaft lock option provides focus lock with no image shift by securing the shaft (not pushing against the drawtube). Choose from many styles of non vignetting flanges so the focuser is permitting maximum light through put. Beautiful anodized colors and custom machining (by request) make for a perfect, one of a kind focuser, to match your SCT, Vixen, Tak Mewlon, or Questar

MoonLite's new SCT focuser configuration for imaging uses a special design that allows a focal reducer to be installed inside the focuser by threading it into the drawtube. The focuser is then installed on to the visual back. The focal reducer travels with the drawtube as the focuser is racked in and out providing the correct distance for imaging. This configuration requires one of 3 special flanges to be picked below, and a special .95" travel drawtube threaded just for focal reducers. This focal reducer option will only work on SCTs that have the large 3 1/4" threaded visual back such as Meade 10" 12" 14" and Celestron's 11" and 14" scopes. We also have a special 4" flange version for Meade's 16" visual back

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 AR5 flange fits the Meade AR5, Sky Watcher 5" refractors, and Antares. Plus other brands that use the same size OTA/ focuser configuration.

The modular design of the CR 2" format Newtonian focuser makes it very versatile. Just pick the options you need in these 3 categories: Drawtube, Focus knob/motor, and Color.

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. Both the DC servo drive motor option and our "High Res" stepper motor option use PC based interfaces, providing automated focus ability running today's ASCOM software. Many different draw tube travels and configurations are available. Our collimatable tip tilt base design provides flexibility for achieving perfect mechanical centerline collimation should the need arise. Light weight plus custom anodized colors and a matching drawtube options make for a perfect custom focuser to match your scopes requirements.

MoonLite offers 14 different drawtube configurations for the 2" format CR model 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 that is threaded for 2" filters for free ! All Drawtube options are free, except for the filter swing versions. The swing filter option is an additional $100.

Regular drawtubes, single thumbscrew style--- come in 1.5" travel, 1.75" travel, standard 2" travel, 2.37" travel, and 2.75" travel. They are a low profile design and use a single 1/4-20 aluminum thumbscrew (non compression ring style). The standard drawtube is a good choice for regular loads and has the lowest profile of all of the drawtube options. It comes with an 1 1/4"adapter.

Regular drawtube, single thumbscrew style with 3 mini set screws. This is a special variation of the 1.5" travel drawtube, it is tapped with 3 small 8-32 set screws at the top of the drawtube. They can be used to permanently attach very heavy loads and still keep a very low profile with out having to pick the taller 3-thumbscrew compression ring version.

Compression ring drawtubes, 3 thumb screw style--- Feature a brass compression ring with three 10-32 size thumbscrews oriented at 120 degrees apart. They can hold very heavy loads and is a good choice for 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 most Newtonian scopes. The 2" travel version is our most popular custom pick.

Low position compression ring style drawtube. This is a special variation of the short 1.5" travel comp ring drawtube as 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 or some cameras, not at the beveled under cut area. Some Diagonals and CCD cameras brands have bevels back cut in to the 2" OD barrel. MooNLite's "Low position" drawtube solves the misalignment problem and grips across the true 2" OD to properly 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.

Swing filter drawtube------comes in the 2" travel versions only and is offered in both the regular style single thumbscrew version and the comp ring three thumbscrew version. This drawtube is an additional $100 for the filter swing option. Just screw in your favorite 2" filter, (we are partial to the UHC and O-III), and you can swing it in and out of your view with an above board lever located on the draw tube. Your filter rides along in the bottom of the draw tube so focusing, changing eyepieces, or alternating from clear to filtered view is made quick and easy. There is an above mounted lever that swings the filter in and out. This lever travel along with the drawtube so it is easy to reach on the side of the focuser. This particular drawtube has a filter shaft holder that bumps out on the side of the drawtube by about a 1/2", so it is not intended for every scope. A 1/2" notch must be provided in the focuser board for the shaft holder. It also requires the scope have a thin focuser board. This is due to the filter holder having somewhere to swing out to with out hitting the board when the focuser is in a high racked up position. When the drawtube is racked down or in the middle of its travel range, the filter swing can easily swing out in to the open space inside the OTA.
