  • Pegasus Astro DSLRBuddy v2 Controller

    The Pegasus Astro DSLRBuddy v2 Controller is an essential tool for astrophotography, providing a continuous 8V, 3A power supply to your camera and an integrated 2.5A dew heater output from a single compact unit. Accepting a wide 5-15V DC input or power from a USB-C source, its 66mm x 66mm x 28mm body consolidates power and dew control, eliminating the cable management problems of using separate devices in the field.

    Uninterrupted 8V DSLR Power at up to 3 Amps

    End battery swaps during critical imaging sessions like multi-hour time-lapses or deep-sky exposures. When paired with a dummy battery for your specific camera model, the DSLRBuddy v2 delivers a stable, regulated DC 8V output at up to 3 Amps. This ensures your DSLR or mirrorless camera has consistent power for all-night operation without the voltage drop or failure of standard camera batteries in cold weather.

    Integrated 2.5A PWM Dew Heater Output

    The DSLRBuddy v2 features a built-in RCA output that supplies up to 2.5A of current to a dew heater strip or flat panel. A manual rotary knob allows you to precisely adjust the power using Pulse Width Modulation (PWM), with a corresponding red LED that dims and brightens to provide instant visual feedback on the power level. This single feature prevents moisture from forming on your camera lens, saving your images from being ruined by dew.

    Dual 5-15V DC / USB-C Input in a 66mm Footprint

    Designed for maximum flexibility in the field, the DSLRBuddy v2 accepts power from either a standard 2.1mm center-positive DC socket (5-15V) or a modern USB-C connection. The device intelligently and automatically selects the highest voltage source, prioritizing the DC input if both are connected. This dual-input system, along with reverse polarity protection, is housed within a tiny 66mm x 66mm x 28mm enclosure, making it an ideal power solution for portable astronomy setups.

    DSLRBuddy v2: A 2-in-1 Solution vs. Separate Components

    For a typical portable imaging rig, you would need a dedicated adapter to power your camera and a separate dew controller for your lens heater, resulting in two devices and a tangle of cables. The DSLRBuddy v2 consolidates these two essential functions into one unit. While it doesn't replace a multi-channel observatory controller, it streamlines the two most critical power needs for a grab-and-go DSLR setup, reducing weight, complexity, and potential points of failure.

  • What kind of power source do I need for the DSLRBuddy v2?

    The DSLRBuddy v2 is flexible, accepting a 5-15V DC input through its 2.1mm socket (12V DC is preferred for optimal performance) or power via its USB Type C port. You can use a standard field battery, a wall adapter, or even a compatible high-output USB-C power bank.

    Does the DSLRBuddy v2 include the dummy battery for my camera?

    No, this product is the controller unit only. You must purchase the correct dummy battery compatible with your specific DSLR or mirrorless camera model separately. The DSLRBuddy v2 provides the regulated 8V power to that dummy battery.

    How do I power my Nikon DSLR and a dew heater on my 80mm refractor's lens with the DSLRBuddy v2?

    First, connect a 12V DC power source to the DSLRBuddy v2's input. Plug your Nikon-compatible dummy battery into the 8V camera output, and insert it into your camera. Then, wrap a dew heater strip around your camera lens or telescope objective and plug it into the RCA dew heater output. You can then power your entire imaging system for the night, adjusting the dew heater with the knob as needed.

    What does the knob on the DSLRBuddy v2 control?

    The rotary knob controls the power level of the Dew Heater Output only. It adjusts the Pulse Width Modulation (PWM) from 0% to 100%, allowing you to apply the precise amount of heat needed to prevent dew without wasting power or introducing heat currents into the optical path.

    I'm shooting star trails with my Sony mirrorless camera. How does the DSLRBuddy v2 help?

    Star trail sequences require hundreds of long exposures over several hours. The DSLRBuddy v2 eliminates the primary point of failure: the camera battery. By providing a constant 8V power supply from a large external source, it ensures your Sony camera won't die mid-sequence, ruining the final stacked image.

    What happens if I plug the power cable in backwards to the DSLRBuddy v2?

    The DSLRBuddy v2 has reverse polarity protection. If you accidentally connect the power source with the wrong polarity, the device will simply not power on and will not be damaged. This protects your investment from common field setup mistakes.

  • Supply Voltage 5-15V DC (12V DC preferred)
    Reverse Polarity Protection Yes
    Power Input Connectors 2.1mm Centre Positive Socket or USB Type C
    Input Selection Automatic (prefers DC input)
    Camera Power Output 8V DC / up to 3 Amps (2.1mm positive tip jack)
    Dew Heater Output 1 x RCA (2.5A max current), PWM controlled
    Dimensions 66mm x 66mm x 28mm
