Baader Slit Domes – Automatic
Observatory domes with broad up- and over-shutter and that can be controlled remotely, sized from 2.1 to 6.15 meters in diameter. They can be in sync with your remote telescope setup, with endless rotation, horizontal flap movement, and are 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 Atuomatic Slit-Domes are available in sizes: 2.1m, 2.6m, 3.2 m, 5.3m, 6.15m

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.
Specifications

Structure
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.

ENVIRONMENTAL & VARMINT PROTECTION
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.
