MaxDome II : Observatory Dome Control System

MaxDome II is a fully automatic observatory dome control system. Link your dome to a Windows-based personal computer for complete automation including telescope slaving and shutter control. MaxDome works with a wide variety of commercial and custom-built domes.

 

Integrated Telescope/Dome Control

The new MaxDome II dome controller provides flexible, fully integrated observatory dome control. Features include:


  • ASCOM-Standard dome and telescope interfaces
  • Support for Automadome
  • Slave dome rotation to your telescope
  • Rotation-only and full shutter-and-rotation systems available
  • Single or dual shutter operation, with sequencing
  • Wireless shutter control - no unreliable sliding contacts
  • Direct confirmation of shutter open/closed state
  • Safety interlocks automatically close dome upon loss of data from PC
  • Park-before-close option to avoid mechanical interferences
  • Manual override controls for shutter and rotation control
  • Auxiliary auto-close inputs for Boltwood Cloud Sensor or other observatory protection hardware
  • Easily adapted to custom or commercial observatory domes
  • Directly compatible with Sirius Observatories
  • Directly drives 12VDC motors up to 5A. Can operate other motor types through external relays.
  • Field-upgradable firmware

A full MaxDome installation includes two identical controller boards. The main board, which controls dome rotation, connects to the controlling PC. A second identical board, riding on the rotating dome and powered by a solar-charged battery (not included), operates the shutters.



A wireless inductive link provides constant communications between the two boards, allowing for full control and status monitoring. This eliminates the need for clumsy and trouble-prone electrical contacts.
