JMI - Smart Focus

Details

JMI Smart Focus

 

 

The Smart Focus system allows one to remotely control a JMI focuser or MOTOFOCUS unit (not included) using computer software.  Popular CCD software (not included) can be used to automatically focus a CCD camera (a couple of examples are listed below).

For more information, see Purchasing Hints and Motor Control Diagrams where you can compare PCFC, DRO and Smart Focus.  Smart Focus includes a hand control, AC adapter, focuser/encoder cable, serial computer cable and basic focuser control software.  The hand unit has two directional focusing buttons, a variable speed control, a power jack, a DB-9 serial connector and a DRO encoder jack.  It can be operated using a 9-volt alkaline battery (included).

One end of the focuser/encoder cable attaches to the hand control and the other end to the encoder assembly installed on the JMI focuser or MOTOFOCUS motor (required, see below).  The serial cable connects between the hand control and the 9-pin serial port of a PC-compatible computer running Windows 95/98/NT/2000/XP/Vista/7.

Most current laptops do not include a 9-pin serial adapter.  Therefore, you will need to purchase a USB to Serial Adapter (USB to 9-pin Serial).  If you purchase a USB Null-Modem Serial Adapter you will also need a straight-through 9-pin serial cable as apposed to the 9-pin null-modem cable which we supply (please see note regarding serial ports).

JMI's standalone basic focuser control software (included on a CD and on our website) is sufficient to control the focuser through the PC.  Automatic focusing can be accomplished through popular CCD imaging software (not included) such as Cyanogen's MaxIm DL/CCD (using SharpStar) and Software Bisque's CCDSoft (using @Focus).

Product Series

What is a Digital Read Out? The electronic Digital Read Out system provides precise information on focuser position with an easy to read LED display. The four-digit display and focus control are integrated into one hand unit. With unprecedented focusing accuracy you can return to any previous focus position after swapping equipment or users. This is especially helpful when returning a CCD camera to focus after visual verification of the position of your telescope. The DRO system designed for NGF focusers shows movement in millimeters with accuracy to 0.01mm. When installed on a MOTOFOCUS motor, the display units will not be in millimeters but can be used just the same for positioning the focuser. The display units and accuracy will be based on the mechanics of each focuser. What is Smart Focus? Smart Focus is a combination of hardware and software for precise remote control of JMI′s motorized focusers through a personal computer′s serial port. The system can be controlled three ways: 1) manually using the control box, 2) with the included basic focuser control software or 3) through third-party auto-focus functions found in popular CCD imaging software such as Software Bisque′s CCDSoft and Cyanogen′s MaxIm DL/CCD. Auto-focus software automatically brings the system into focus using the CCD camera in conjunction with Smart Focus. (JMI′s focuser control software does not include an auto-focusing function.) The system includes a hand control box (AC or DC power) and PC compatible focus control software. The hand control includes a jack and cable for connecting to the focuser and a 9-pin serial RS-232 connector and cable for software control using a personal computer.
