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, and EGO Battery and TheSky Fusion EGO battery adapter (coming soon), or any 12V DC power supply that provides sufficient amperage to run the connected imaging equipment.

Q. What is the price of TheSky Fusion?

A. The introductory retail price is $1,695.  Beginning September 1, 2020, the retail price will be $1,895.

Q. When will TheSky Fusion ship?

A. TheSky Fusion started shipping July 16, 2020.  Thanks for your patience!

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 out ports on the front panel are Anderson Powerpole® connectors.  Power cables that use these connectors are inexpensive, offer a wide amperage range, and are easy to make for the do-it-yourself enthusiast. These power ports can supply power for the most power-hungry equipment.  Three of the ports have configurable voltage and maximum amperage output.

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 comes with TheSky Imaging Edition.  While at first glance, the TheSky Fusion’s™ software may seem identical to TheSkyX Professional Edition™ with the optional Camera Module, and the optional TPoint Module, TheSky Fusion™ includes additional functionality such as power switching, GPS integration, status screen output and Wi-Fi hot spot integration.


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

With TheSky Fusion™ you can connect your mount, camera, autoguider, focuser, filter wheel, rotator, 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 use a remote desktop application (Remote Desktop or VNC).  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.   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.

TheSky Fusion Hardware Specifications

Category Feature/Specification Details
External Case CNC-machined 6061 aluminum housing


The external housing is CNC machined from aluminum and anodized red.

  • Dimensions (W x H x D): 19.7 cm x 7.6 cm x 13 cm (7.8 in. x 3 in. x 5.1 in.)
  • Total weight: 1.9 kg (4.2 lb.), including the dovetail mounting bracket.
Computer 64-bit Six-Core CPU at 1.8 GHz Coupled with fast DDR4 RAM, and a discrete GPU, the fast CPU offers an ideal image acquisition experience.

  • Smooth Sky Chart updates.
  • Efficient live stacking.
  • Fast image archiving.
GPU Discrete GPU supports OpenGL graphics hardware acceleration for smooth panning and zooming.
  • 4 GB of DDR4 RAM
  • 64 GB of high-speed eMMC storage
  • 256 GB of mass non-volatile storage
  • TheSky consumes about 5 GB.
  • The complete Gaia stellar database occupies an additional 90 GB of mass storage.
  • 25 GB available high-speed memory and 165 GB of mass storage. This means you have ample storage for an entire night’s worth of full-frame images, even using a large-format camera:
  • About 6000 images at 30 MB each.
  • About 1900 images at 100 MB each.
Computer Power Requirements ARM-based CPU Here is the processor’s approximate power footprint under varying operating conditions:

  • 2 Watts (processor idle).
  • 4 Watts (typical workload usage).
  • 8 Watts (maximum CPU draw).

A laptop’s power consumption can vary from 30W to 90W. Comparably, TheSky Fusion consumes about 1/10 to 1/4 as much power.

Wired Communication Gigabit Ethernet
Wireless Communication 802.11AC 2.4 or 5.0 GHz Wi-Fi The fastest widely available Wi-Fi standard and allows for the best possible wireless experience. The built-in Wi-Fi antenna can be upgraded to a Reverse Polarity SMA Wi-Fi antenna.
GPS Built-in The GPS gets accurate time and position data. This simplifies nightly setup and eliminates common mistakes, for example, entering the location or time incorrectly or neglecting to update them.

Real-time access to the site’s precise position and time ensure optimal telescope pointing accuracy with TheSky Imaging’s TPoint telescope modeling.

The default antenna is mounted internally. An optional external antenna (sold separately) can be attached to the External GPS Antenna port.

External Power Ports Eight Anderson power pole connectors


Anderson Power Products’ Powerpole® connectors and cabling offer:

  • Low cost off-the-shelf cables.
  • Variety of readily available of amperages and wire gauges (15A/30A/45A contacts supporting 10–20 AWG wires).
