You observatory will be one of three possible types (design iterations):


The latest model, a replacement for DFNSMALL. It does everything the DFNSMALL can do, but has 3 hard drives instead of 2, a more capable PC and is easier to build, repair and maintain. EXT systems required 12 V power and must be connected to the internet (via Ethernet, WiFi or mobile broadband).

DFNEXT and DFKSMALL observatories have the same box size and mount bolts on the back, which means they are fully interchangeable on the existing stand/mount.


This is the most common fireball observatory in the Australian DFN. The design has both video and still lenses and is easily recognised by the dual drive enclosure on the door. SMALL systems require 12V power.

The KIT systems are a smaller and less expensive design. The design has no video system, and only one 3.5 inch drive for storing data. It also has no on/off capability, so the DSLR, the fan, and the external drive are always powered. KIT systems require AC mains power and an Ethernet or mobile broadband connection.
