What software is compatible with the Focuser Boss II?
The Focuser Boss II is compatible with any ASCOM-compliant software on Windows, including popular applications like Sequence Generator Pro (SGP), N.I.N.A., Maxim DL, and FocusMax. For macOS users, it is fully supported in TheSkyX (daily build 7315 or later) and Equinox. You can also control it from any device with a web browser using its built-in web server.
Can I control the Focuser Boss II without a computer?
Yes. With the optional Hand Controller, you can make manual focus adjustments using push buttons directly at the telescope. Additionally, if you install the optional 802.11 WiFi module, you can connect to the Focuser Boss II from a smartphone or tablet and use the web interface to control the focuser without a dedicated PC.
How do I choose the right HSM motor for my 3.5" Feather Touch focuser?
For a 3.5" Feather Touch focuser, you need the HSM35 motor. This motor is specifically designed to provide the necessary torque for moving the larger drawtube and heavier imaging loads associated with 3.5" and 4.0" class focusers from both Starlight Instruments and Astro-Physics.
How does the temperature compensation on the Focuser Boss II work?
With the optional Temperature Sensor attached, the Focuser Boss II system monitors ambient temperature. As the temperature changes during an imaging session, which causes the telescope's optical tube to expand or contract, the ASCOM driver automatically adjusts the focus position by a pre-calibrated amount to maintain perfect focus without manual intervention.
Can the Focuser Boss II control two focusers at once?
Yes. The standard Focuser Boss II hub controls one focuser. By installing the optional 2nd Focuser Control Board, you can control two Feather Touch focusers simultaneously and independently from the same hub. This is ideal for dual-rig setups or managing a main focuser and a guide scope focuser.
What power options are available for the Focuser Boss II in the field?
The Focuser Boss II requires 12VDC power. While an AC/DC power supply is available for home or observatory use, for field operation you can power it using the optional DC Cigarette Lighter Plug Cable connected to a portable 12V battery pack or power tank.
