  • Pegasus Astro Temperature Sensor for FocusCube v1 & v2 (RJ45)

    This external temperature sensor for the Pegasus Astro FocusCube v1 and v2 enables precise, automatic focus compensation by feeding ambient temperature data to the controller through its 1.2m cable and RJ45 connector.

    Automated Focus Compensation: A 1.2m Sensor for Thermal Stability

    As ambient temperature drops during an imaging session, a telescope's optical tube contracts, causing the focal point to shift. This sensor allows your FocusCube v1 or v2 controller to automatically counteract this thermal focus drift. The 1.2m cable provides enough length to place the sensor in a location that accurately measures the ambient air temperature, away from heat generated by the focuser motor or other electronics.

    • Maintain Sharp Focus: By providing real-time temperature readings, the sensor allows the FocusCube to make micro-adjustments, keeping stars pinpoint sharp throughout the night.
    • Plug-and-Play: The RJ45 connector ensures a secure, simple connection directly to your FocusCube v1 or v2 control unit without any complex wiring.
    • Reliable Data: Placing the sensor correctly is key to accurate compensation, and the 1.2m cable length is critical for achieving this separation from your imaging equipment.

  • Why do I need the Pegasus Temperature Sensor for my FocusCube?

    You need this sensor to enable the automatic temperature compensation feature of your FocusCube v1 or v2. As the temperature changes overnight, your telescope's optics will expand or contract, shifting the critical focus point. This sensor provides the necessary data for the FocusCube to automatically adjust the focuser and maintain sharp stars without manual intervention.

    Is the Pegasus Temperature Sensor compatible with the FocusCube v3 or other controllers?

    No, this specific sensor is designed with an RJ45 connector for use only with the FocusCube v1 and FocusCube v2. It is not compatible with newer versions of the FocusCube or other Pegasus Astro devices that may use a different connector type.

    Where should I place the Temperature Sensor for my SCT for the best results?

    For the most accurate readings with a Schmidt-Cassegrain Telescope (SCT), mount the sensor near the front of the optical tube, but ensure it is measuring the open air and not touching the metal tube directly. The goal is to measure the ambient temperature that the telescope is operating in, not the heat retained by the telescope's mass. The 1.2m cable allows for this flexible placement.

    Can I use this sensor to monitor dew point?

    This sensor only measures temperature. To calculate the dew point and control dew heaters, you would need an environmental sensor that measures both temperature and humidity, such as the one included with the Pegasus Astro Ultimate Powerbox or Pocket Powerbox series.

    What is the length of the cable on the Pegasus Temperature Sensor?

    The sensor comes with an attached 1.2-meter (approximately 47 inches) cable, terminating in an RJ45 plug for direct connection to the FocusCube v1 or v2.

    Will my imaging software like N.I.N.A. or SGP recognize the Pegasus Temperature Sensor?

    Yes. When connected to a compatible FocusCube, the temperature data from this sensor is passed through the ASCOM driver to your imaging software. Applications like N.I.N.A., Sequence Generator Pro, and others can then use this data to trigger their own autofocus routines based on temperature changes.
