Q. What astronomical devices (mounts, cameras, autoguiders, focusers, rotators) does TheSky Fusion support?

A.  Please see TheSky Fusion Specifications document on the Documentation tab below for a complete list of supported hardware.

Q. How do I register my TheSky Fusion serial number?

A. Go to for instructions for emails your serial number to Software Bisque.  Please allow two business days for the serial number to be processed.  Thanks for your patience.

Q. Does TheSky Fusion include a power supply unit?

ATheSky Fusion does not include a power supply unit.  It can be powered using TheSky Fusion Power Supply Unit, or an EGO Battery with TheSky Fusion EGO battery adapter (coming soon), or any 12V DC power supply with a suitable Anderson Powerpole cable and that provides sufficient amperage to run the connected imaging equipment.

Q. What is the price of TheSky Fusion?

A. The retail price is $1,895.

Q. When will TheSky Fusion ship?

A. TheSky Fusion started shipping July 16, 2020.

Q. What equipment can TheSky Fusion control?

A. See Supported Devices in TheSky Fusion Specifications (PDF) document for details about supported telescope mounts, cameras, autoguiders, focusers, filter wheels, and rotators.  We will update this list as additional equipment is supported.

Q. How can I connect to and control my astronomy equipment?

A. TheSky Fusion can be used to control your astronomy hardware wirelessly with Wi-Fi (as a hot spot, or connected to an existing network) or hard-wired with Ethernet from any desktop, laptop, smartphone or tablet computer.

Q. Why is TheSky Fusion equipped with a GPS?

A. TheSky Fusion’s integrated GPS unit ensures that TheSky’s location, date and time are always up to date and accurate.  Always having accurate location and time means one less thing to worry about, and is essential to maintain precision telescope pointing accuracy. And, if you own a Paramount, this level of accuracy will optimize Pro Track-assisted tracking performance.

Q. What are the red and black connectors on TheSky Fusion?

A. The eight power output ports on the front panel are Anderson Powerpole® connectors.  Power cables that use these connectors are inexpensive, capable of handling high amperages, and are easy to make for the do-it-yourself enthusiast. These power ports can supply power for the most power-hungry equipment.  The output voltage on three of the eight ports is configurable.

Q. Can TheSky Fusion’s internal storage be increased?

A. TheSky Fusion comes with 256GB of ‘mass storage’ in the form of a microSD memory card.  This card is removable and can be replaced with a higher capacity memory card (for example, a 512GB or 1TB microSD card, sold separately).

Q. If I already own TheSkyX Professional Edition for Windows or Mac, can I transfer this license to the Linux-based TheSky Fusion™?

A.  In short, no.  TheSky Fusion includes TheSky Imaging Edition.  While at first glance, it may seem identical to TheSky Imaging Edition on macOS or Windows, TheSky Fusion™ includes additional functionality such as power switching, GPS integration, status screen output and Wi-Fi hot spot integration.

Q. What is TheSky Fusion warranty?

TheSky Fusion™ marries TheSky Imaging edition, the world’s single-most capable object-acquisition and imaging software, with intelligently designed hardware to connect, power and integrate your imaging equipment.

With TheSky Fusion™ you can connect your mount, camera, autoguider, focuser, filter wheel, rotator, power switches, and dew heater to TheSky Imaging edition to control them all from your tablet, smartphone, laptop, or desktop.

Operate your equipment from any modern web browser through Wi-Fi or the VNC app.  An Ethernet port even permits a hardwired connection for an optimal experience.  Though an Internet connection is not required, TheSky Fusion takes full advantage of being on-line when connected to the Web.

TheSky Fusion attaches to your mount and simplifies system setup, maintenance, and nightly tasks for maximum productivity.  TheSky Fusion’s flexible power-output ports can drive even the most complex hardware configurations; that means you won’t need to bring a power supply for each of your devices because TheSky Fusion powers them all.  Four high-speed USB 3.0 ports and one legacy serial port can meet most communication needs.  If not, one of the configurable 5V DC power ports can add an optional powered 4- or 7-port USB hub to provide up to 11 total USB ports.
