Give your EXOS-2 GoTo control
OnStep V5 Pro · Maxvision EXOS-2 upgrade kit
Add GoTo pointing and motorised tracking to your Maxvision EXOS-2 with the Terrans Industry OnStep V5 Pro retrofit kit. Supplied as a controller, motor and belt-drive upgrade, it gives an existing compatible mount a route to app and computer control for observing and astrophotography.
- Find targets through GoTo. Once the mount is installed, configured and aligned, use compatible control software to select and slew to objects.
- Control both axes. The RA and DEC motor assemblies connect to the mount through the supplied pulley and belt components.
- Choose a suitable control device. Wi-Fi, Bluetooth and USB provide connection options for supported phone, tablet and computer software.
A GoTo conversion for your existing mount
This kit suits an owner who wants to keep a compatible EXOS-2 and add OnStep control. It is a hardware retrofit: fitting the drive components, adjusting belt tension and configuring the system are part of the installation.
Sidereal, solar and lunar tracking rates let you select the rate appropriate to the target. For imaging, the controller can form part of a wider computer-controlled setup. Exposure length and guiding results still depend on the mount's mechanical condition, balance, polar alignment and the rest of the equipment.
Choose the correct mount version
This is the Maxvision EXOS-2 version. Please ask us to check fitment before ordering for a Bresser-branded EXOS-2, an iEXOS model or a mount with different motors or brackets. A similar model name alone does not confirm the same installation.
Connect the way you observe
App or computer control
Terrans lists support for OnStep-compatible mobile control and computer use through ASCOM or INDI. Choose software and drivers that support your operating system and the connection you intend to use.
For a computer-led imaging setup, this provides a route to integrate mount control with compatible acquisition, planetarium and guiding software. A guide camera, guide optics and imaging camera are separate parts of that setup.
Plan the power supply
Use a suitable 12 V DC supply rated for at least 3 A for the kit alone, with the specified 5.5 × 2.1mm connector. Check the controller markings and manufacturer instructions before connecting power; additional powered equipment needs its own power budget.
From installation to first target
- Fit the drive hardware. Follow the mount-specific instructions for the motor brackets, pulleys and belts. Check clearance and movement before powering the system.
- Connect and configure. Connect the motor cables and suitable power supply, then set up the chosen app or computer connection using the manufacturer's guidance.
- Balance, align and test. Balance the complete telescope setup, polar-align the mount and complete the required pointing alignment. Check slews and cable clearance before starting an observing or imaging session.

A compatible Maxvision EXOS-2 mount, suitable 12 V DC power supply and a supported control device with the necessary software.
Mount, tripod, telescope, camera, guiding equipment and a separate hand controller are not part of this upgrade-kit listing.
Before you order
Will it fit any mount called EXOS?
This is the kit specified for the Maxvision EXOS-2. Other EXOS-branded mounts can have different drives or mounting arrangements. Send us the full model name and photographs if your mount differs from this specification.
Does the kit include a complete telescope mount?
No. It is a motor and controller upgrade for an existing compatible Maxvision EXOS-2. Your mount, tripod and telescope are required separately.
Can I use it for astrophotography?
It can provide the mount-control part of a compatible imaging setup. Accurate polar alignment, sound mount mechanics, careful balance and suitable guiding equipment remain important. Installing a GoTo kit does not establish a new payload rating or guarantee a particular exposure length.
Do I need a separate hand controller?
A separate hand controller is not essential when using a supported app or computer connection. If you prefer a handset, check its compatibility with this V5 Pro controller before ordering it.
Let's check your mount
Send Dark Clear Skies your mount's full model name, a photograph of its drive area and the device you would like to use for control. We can help check the version and setup requirements.
