INDI Library is an open source software to control astronomical equipment. It is based on the Instrument Neutral Distributed Interface (INDI) protocol and acts as a bridge between software clients and hardware devices. Since it is network transparent, it enables you to communicate with your equipment transparently over any network without requiring any 3rd party software. It is simple enough to control a single backyard telescope, and powerful enough to control state of the art observatories across multiple locations
