BASIC Stepper Focus Motor Kits for
Crayfords and Rack & Pinion Focusers
• Fully ASCOM and INDI compliant software drivers supporting Windows xp/vista/7/8/10/11 for operation from your PC through a usb cable.
• Full step and half step control from computer and display of step count, Supports Relative and Absolute focusing, forward and reverse direction.
• Store five positions for major changes in focus (e.g., camera1 to camera2 to eyepiece type '1' to eyepiece type '2'). Just focus once and save the position and a label for later 'GoTo' .
• ASCOM has undergone a rapid transformation from Windows-only to a universal technology. Classic ASCOM has been a fundamental cornerstone of astronomy innovation on the Windows platform. Classic ASCOM seamlessly operates in the background of many of the products you are currently using by providing the same universal language so that any astronomy app/program can connect to any astronomy device which complies with the ASCOM standards.
• Design: MODULAR - Buy just the components you need. Affordable upgrade path to more nSTEP features and online firmware improvements. Unlike all-in-one boxes, Modular design provides easy repair or replacement of components.
• Maturity: Since 2010 with over 1000 installs of our focus kits. Fully checked out for compatibility with the most advanced Autofocus software, including ASCOM and INDI drivers.
• 12V power for stepper included.
• Compatible with Moonlite, Robofocus and other uni-polar stepper focus motors.
nSTEP Stepper Motor
Don't have a focus motor? Motorize your focuser with our high torque 12V DC Stepper driven by our powerful usb-nSTEP controller. Just check our gallery to the right for popular ones.
Got a focuser that's not in our gallery? We've done over 100 different types and variations including Williams Optics, Takahashi, Coronado, JMI, Astro Tech, Baader, Borg, Cave, Meade, Skywatcher, Tectron, TMB, Vixen, Cave, Zhumell. With a couple of photos and a few simple measurement we can craft a STEPPER focus motor kit that will fit yoru focuser at no additional cost. E-mail us at rigelsys0@gmail.comand we'll get it started.
• Step resolution: Gear coupling of motor to focus shaft provides up to 9,600 steps per revolution in full step mode and 19,200 in half step mode to supply the very fine focus movement required for fast telescopes and camera lenses.
• Max focus knob rotation speed: 17 deg/sec
• Bracket kits & gear ease of installation: Tailored to each focusers for ease of attatchment, each kit contains all the parts needed for each particular focuser.
• Manual focusing with focuser knobs: Gear coupled motor easily declutched for manual focusing using focus knob.
• Added weight on telescope: Mere 250 grams
• Adding more scopes: User can add just a bracket and gear kit ($70) to a different scope and move the focus motor or add bracket and motor ($109.95) and just swap the wifi-nFOCUS between them.
nSTEP Temperature Sensor
• Optional Temp sensor: has its own dedicated port. 0.1 degree C resolution per measurement
Telescopes change focus as temperature changes expand/contract the length of the telescope tube as temperature increases/decreases. Adding the external temperature sensor to the usb-nFOCUS adapter allows your autofocus software to and automatically compensate for these temperature changes. Unlike internal temperature sensors located inside the controller that are affected by the heat generated by the electronics, the external temperature sensor can be attached to the telescope to get a more accurate measurement of the ambient temperature.
Buy usb-nSTEP and STEPPER focus motor at the same time on our website and we'll include the temp sensor free.
