wifi_nFOCUS ADVANCED Encoded DC Focus Motor for Celestron & Meade SCTs from PC, Pushbuttons, Tablets & Phones using Wifi

Fully ASCOM compliant so it will work with popular focus control programs. Can be operated for temperature compensation with the included temperature sensor. USB and 12V battery power cables included. Software and ASCOM drivers for Windows xp/vista/7/8/10/11. Approximately 1.5 inches wide by 4 inches long by 0.5 inches thick.

Full operation from your PC via ASCOM through a usb cable plus integrated push buttons, wifi operation from cell phone or tablet and ALPACA  wifi connectivity to your PC through your observatory wifi access point. using ASCOM and INDI compliant software drivers supporting Windows xp/vista/7/8/10/11.

Gear coupled motor prevents binding of focuser shaft and provides the equivalent of 4300 steps per revolution. Supports fast focusing with up to 300 degrees/sec rotation of focuser knob Light weight motor only adds 160 grams and does DOES NOT HIT the mount at high Altitudes/Declinations. Gear coupled motor easily declutched for manual focusing using focus knob.

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. Now we have ALPACA, a new way to accomplish the same things but via network connectivity and on any platform, even embedded controllers. Both ALPACA and Classic ASCOM seamlessly operate in the background of many of the products you are currently using. Both provide the same universal language so that any astronomy app/program can connect to any astronomy device which complies with the ASCOM standards. ASCOM has become essential through simplification and standardization.

ALPACA compliant devices such as the wifi-nSTEP can be network connected and communicate through ASCOM's HTTP/REST ALPACA  protocol. In the ever-evolving field of astro-photography where fast optics and advanced camera devices are essential, maintaining accurate focus is critical. Wifi-nSTEP’s built-in web server provides full integration into ALPACA that enhances the user experience by providing fast, reliable, and precise focusing of your telescope from an ALPACA  dynamic client as well as control and monitoring from any device with a web browser such as a smart phone or tablet. 

Celestron kits available to fit 6, 7, 8, 9.25, 11, 14 inch models made since 2006 and avaible for pre 2006 models. Meade kits fit their full range of sizes and models.

Temperature Sensor Included

• • 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.
