The new CHL 2.5” large format focuser features a low profile hybrid design to allow focal reducers to be used inside the focuser. Now fitted with Moonlite High Resolution Stepper Motor Kit With Mini Controller V2.
We make 3 versions: one for EDGE 8” using the .7” EDGE reducer; one for EDGE 9.25” using the Lepus Telecompressor #19410; and for the EDGE 11” / 14” using the large EDGE .7 Celestron brand reducer. All CHL focusers will work with out the reducer installed as well.
CHL focusers for EDGE 8" and 9.25" scopes include a special short profile replacement knob kit. The machined aluminum knobs replace the stock plastic mirror lock and focus knobs. The knob design along with a tapered bottom focuser flange shape allows the CHL 2.5” large format focusers to thread on to the visual back in a very low position. This super low profile along with the reducers fitting up in the large format focuser’s drawtube provide much needed back focus for imaging set ups. We also include a special 68mm to Recessed T-thread adapter along with the normal 2” and 1 ¼” comp ring thread in tops. All 3 thread in tops come standard with any of these CHL model focusers.
CHL focuser for EDGE 11"/14"inch scope includes:
3 ¼” threaded flange Fits both the 11" and 14" EDGE OTAs, with or with out a reducer installed in front of the focuser.
Special 68mm to- recessed T-thread with lock ring adapter included free.
No Knob kit is needed with the 11" and 14" EDGE scopes as the stock knobs are away from the focuser and do not pose any limitations.
The CHL focuser for the 11”/ 14” EDGE scope can use the Large EDGE .7 reducer. The reducer needs threaded on to the visual back first, then the focuser threads on to the reducer. The 146mm back focus specs allows enough room for both the focuser and camera in most configurations. However adding an OAG may place the spacing to far out. Note the Lepus reducer at 101mm spacing does not work with the CHL EDGE focuser on the 11/14", Please use the correct .7 EDGE reducer from Celestron that provides the 146mm back focus space.
Standard -The standard CHL comes with our heavy-duty 1.5" Tri-knob option. It is a dual rate (2 speed) configuration using our extremely smooth 8 to 1 reduction unit. It uses large 1.5" OD knobs and has both a coarse and a fine knob on one side and a coarse on the other. The larger tri-knob option is a heavy-duty version of the regular dual rate system found on our smaller CS focusers and has increased lifting capacity to 6 lbs. The fine focus adjustment knob is on the right by default, but can be made a lefty if needed.
Tri-knob w/Lock ($25) - The Tri-knob with LOCK knob option adds the shaft lock system to the coarse 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 shaft lock ability along with the 6 lb heavy-duty reduction unit make this option ideal for heavy demanding loads for both visual and imaging requirements.
DC Motor ($195.00) – The DC motor with slip clutch option uses our Dual channel battery operated hand controller. It allows adjustable speed control for focus on the first channel, and the 2nd channel is available for running a 2nd focuser, or our rotating flange option. The Slip clutch feature on the motor allows both manual operation using the knobs and electronic hand controller operation at the same time. The DC gear head motor and controller combination are ideal for operation of the focuser when a Computer is not going to be used. The DC motor is ideal for visual or imaging and provides a 8 lb lifting capacity when installed on the focuser.
High Resolution Stepper Motor/stand alone ($190.00) for customers that may all ready have a stepper motor controller. – The high resolution stepper motor option provides extremely fine .00008" focus resolution. The motor provides an 8 lb. load capacity once installed on a CHL focuser. It gives the focuser great repeatability and automated focus ability for today’s imaging requirements when using a PC. The high resolution stepper motor’s slip clutch feature allows both manual operation using the focusers knobs and electronic PC control at the same time. The stepper motor follows the 9 pin DBA standard pin out so it will work with ROBO focus (pin for pin) controllers along with many other brand controllers. We offer two different controllers below if you do not have a controller. Please see Motor options for more details: Motor Focus Options
High Resolution Stepper Motor with MoonLite Mini V2 Controller ($440.00) – The high resolution stepper motor with mini V2 ASCOM compliant controller. The MoonLite Mini controller features a remote temp probe, Speed control and up/ down buttons on the controller box for manual operation of the motor alone with full PC control. It uses a USB connection to your PC and runs off standard 12 volt DC. We include an AC adapter with a universal plug so it will work in any country, USB cable, 9pin DBA cable, and remote temp probe. Works with all ASCOM based software once the driver is loaded. We also include a Non- ASCOM program for customers to operate the focuser that may not have ASCOM set up. The 8 lb. load rating and precise focus ability make this a good configuration for permanent or remote imaging platforms. The slip clutch feature for manual knob operation is always included with all Motor options so the focuser can be used in many configurations, manual knob, controller buttons, or remote PC operation. Please see Motor options for more details: Motor Focus Options
High Resolution Stepper Motor with Dual Port DRO Display Controller ($685.00). This option includes a 2 port controller and can operate 2 separate focusers at the same time, or 1 focuser running both focus and a rotator. It is a full ASCOM compliant controller along with the high resolution stepper motor with slip clutch. Along with our ASCOM driver, we also include a basic Non- ASCOM program for customers to operate the focuser that may not have ASCOM set up. This controller is best for both visual and PC operation due to its buttons and full DRO display on the controller box located at the scope. It has a fine and fast mode using the buttons on either channel with a full DRO position readout on the display that shows the exact step count position just like in the software of your favorite imaging program. The controller has a remote temp probe just like the mini V2 above and full digital display, plus manual buttons for stand alone use. The 8 lb. load rating on a CHL model focuser and extreme precise focus ability at .00008” resolution and repeatability make this the ultimate configuration for permanent and remote imaging platforms. This controller / stepper motor option is recommended for both PC and hand held manual operation. It comes with universal voltage AC adapter and USB cable. The slip clutch feature for manual knob operation is always included with all Motor options so the focuser can be used in many configurations, manual knob, controller buttons, or remote PC operation. Please see Motor options for more details: Motor Focus Options
Moonlite High Resolution Stepper Motor Kit With Mini Controller V2
Image for illustration only
All MoonLite's High Resolution stepper motor options use a premium, low backlash Hurst stepper motor. This provides very fine .00008" resolution and accurate position repeatability required for today's high end imaging systems. It comes as an option on all single and dual rate model focusers (SCT, Refractor, and Newtonian). It has such a fine variable rate that the reduction unit is not needed, so it is not offered on dual rate focusers. The Power slip clutch system allows both motor and manual focus control of the focuser at any time.
The miniV2 is an ASCOM compliant stepper motor controller for Moonlite's High Res Stepper Motors. The controller works with all ASCOM based software packages out there today such as Focus Max, CCDSoft, MaximDL, etc. Besides ASCOM drivers for both 32 bit and 64 bit systems, we also provide an Non ASCOM software program for customers that are not running ASCOM based programs and need only a basic program to operate the focuser on a PC. Works great for a simple remote focus solution. The miniV2 controller has built in temperature sensor as well as a remote temp probe. The controller runs on 12 Volts DC and we include an AC adapter that has all the different plug configurations (US, Europe, UK, and Australia); however, most customers will simply use 12-volt power off their mount. This new miniV2 controller is designed to be used by a PC or its manual buttons and speed control knob for manual operation at the scope. All cables are included with the controller.
