Description

This list is open to all current and potential owners of Sirius fibreglass dome observatories. Its aim is to allow for the free exchange of information, experiences, ideas, and to raise and answer questions relating to these popular observatories (over 500) now in wide use around the planet. Ancillary equipment directly relating to dome operation (rotation/shutter control, cloud/weather systems, electrical systems, etc) are also welcome topics. While this is an independent forum, relevant equipment makers and suppliers are invited to participate.

Power supply vs. battery
