LakesideAstro Motor Focus System - Dependable, reliable and accurate auto focusing

BoxThe motorised focuser from LakesideAstro has been designed and built in the UK. It is a stepper motor focusing system (shown here attached to a Moonlite Crayford focuser) which is fully compliant with ASCOM and can be used with all the usual programs such as MaxIm, CCDSoft, FocusMax and many more.

It has an integral 16 character x 2 line LCD display which shows the position of the focuser and provides on screen access to the calibration routine, setup routines, precise manual control and other user functions.

The motorised focuser can also be controlled by using the push button switches to provide manual focusing. The unit is provided with a all necessary cables, installation CD and suitable bracket and coupler to connect the stepper motor to the telescope. For a full description of the system see other pages on this site.

The LakesideAstro motorised focuser system is designed as an add on for your existing telescope system. The stepper motor will be provided with a customised bracket to connect the motor to the telescope and a shaft coupler that will replace one of the focusing knobs of your existing focuser. It is ideal for use with most of the popular Rack & Pinion and Crayford focusers.

Customised brackets are available for a wide range of telescopes and commonly used focusers. We are continually adding new brackets and are able to provide custom solutions if required.

There are two main components of the system, i.e. the control unit and the stepper motor assembly.

Important: We no longer include a 2m power lead as people often needed something longer or with different connectors so instead we have reduced the price and recommend you buy a suitable power lead for your needs, the unit uses a 2.1mm 12v DC connection, these Lynx Astro cables are a good match: Lynx Astro Silicone Power Cable 2.1mm DC Jack to 2.1mm DC Jack or Lynx Astro Silicone Power Cable for Sky-Watcher Mounts.

Control Unit:

BoxThe control unit is fitted with a 16 character by 2 line LCD display and three push buttons. The unit is fully ASCOM compliant for use with programs such as MaxIm DL and FocusMax etc., and has been tested with Windows XP, Vista and Windows 7.

The unit has a professionally made high quality printed circuit with full silk screen and solder mask for long term reliabilty.PCB

The display has a variety of uses which can be accessed via the three push buttons. The centre button is used to select the various modes whilst the outer two buttons are used for manual control or for setting the parameters of the system. The modes available are AUTO, MANUAL, PRESETS, SETUP and TEMP.

The default mode is AUTO which is used for autofocus using any suitable ASCOM compliant programs such as MaxIm DL, CCDSoft and FocusMax etc. The focuser position is shown on the LCD display in this mode.

When in MANUAL mode the motor can be driven using the buttons on the unit. When a move IN/OUT button is pressed the motor speed starts at a low rate to enable precise positioning and ramps up to maximum speed if the button is held down. The LCD display shows the focuser position at all times. When in manual mode it is possible to set a backlash value.

The PRESETS mode allows you either save up to three positions or goto one of the previously saved positions. This could be useful if you are using the unit in manual and swapping eyepieces or imaging equipment which have different focus positions.

Also provided is a special routine for 'parking' the focuser which could be useful if you are using a mobile setup. This will allow you to move the focuser to a preset position, e.g. with the tube fully closed for packing away the telescope. Whenever the 'park' command is initiated it automatically saves the original position so that on subsequent use the focuser can be returned to that position using the 'unpark' command.

The SETUP mode provides on screen access to routines to allow you to calibrate the system or to select step size, direction of movement and the backlash for manual use.

The TEMP mode will display the temperature from either the internal or optional external digital temperature sensor. The temperature will also be displayed in programs such as MaxIm and FocusMax.

Temperature tracking is now provided which will work with all the usual programs such as MaxIm DL and Focusmax to automatically adjust the focus position to compensate for temperature changes. The temperature sensor is now mounted externally close to the motor as standard to provide more accurate temperature readings.

Stepper Motor Assembly:

FTThe motor assembly consists of a stepper motor and gearbox with a custom bracket and shaft coupler to suit the users telescope or focuser, shown here attached to a 3.5" FeatherTouch Focuser.

A selection of standard brackets and couplers are offered to fit a variety of telescopes and new brackets are always being added to the range. We would be happy to provide non standard items on request.
