Baader Slit Domes – Classic

Observatory domes with broad up- and over-shutter and that can optionally be controlled remotely, sized from 2.1 to 3.2 meters in diameter. They can be in sync with your remote telescope setup, with endless rotation, horizontal flap movement, and are optionally fully ASCOM and INDIGO compatible – or via dedicated API.

Classic Slit Domes are typically used by private individuals and they can be operated manually or with a motorized sub-system controlled via a hand controller or remotely. These are typically used for smaller telescope setups that have up to a 600mm aperture.

Baader Classic Slit-Domes are available in sizes: 2.1m, 2.6m and 3.2 m

All Baader Slit Dome models include

Installation Performed by Baader personnel at the customer site
Warranty 2 years warranty for all electronic and electric components
10 years warranty for outer dome skin and dome mechanics
We warrant for 200km/h wind speed to achieve undeteriorated performance and protection of the dome interior, with the dome being closed and in parking position
Fail-safe Features Hand crank system to close dome in case of power failure
Ready for Emergency Weather Station

Required for all Baader Slit Domes:

Either short cylinder (A) or cylindrical base (B)

The short cylinder is the interface between the dome and the structure is it to be installed on. The cylindrical base is another option that can be incorporated to maximize the interior of an observatory.



Built as a self-contained structure made of Fiberglass Reinforced Polyester (FRP) with dual slit arches that is mounted on a precision laser cut steel ring, an up and over shutter, and a horizontal flap.

Endless dome rotation

Supplied with a Continuous Power Bar (CPB) enabling endless dome rotation and permanent remote control of the shutter and horizontal flap.


Protecting your system is critical for the functionality and longevity of the housed equipment, hence, silicone seals are used to mitigate the entry of unwanted particles and varmint.

Inner Surface

The inner surface of the dome is coated with a non-reflective paint to mitigate stray light from affecting data collection and avoid hotspots to form during daytime operation.

Optional Upgrades

Automated Dome Control

An electronical controller with an interface that enables the end-user to control the dome locally with a hand control unit and remotely via direct drivers, API, ASCOM or INDIGO.

 Emergency Weather Station (Required for Remote operation)

A component that is hardwired to the control sub-system which commands the dome to close in case of precipitation or high wind speeds.

For customers that desire mechanical through-holes with flanges and holders for electronic equipment.
Another fail-safe feature that is incorporated and only utilized for the dome to ensure self-closure in case there is a power failure.
Downward-radiating wall lights can be provided in red and white light which can be separately controllable and dimmable.
An indoor and outdoor camera can be supplied to provide awareness of the status of your observatory.
Depending on your site’s age and location, an air dehumidifier is recommended to control moisture levels and create overpressure inside the dome.
