Together with the University of New South Wales, and in addition to the Australia Telescope Compact Array (ATCA), the Narrabri branch of the CSIRO/ATNF also operates a 22-m millimetre telescope at Mopra. It is located close to Coonabarabran, near the road to Siding Spring (the site of the Anglo-Australian Observatory, AAO), at an elevation of about 1200 m.
The Mopra telescope operates at wavelengths of 2.6 mm to 20 cm, which means that it can observe, amongst others, the important lines of HI and CO. It is mostly used for molecular line studies and Very Long Baseline Interferometry (VLBI).
By the foot of the 22-m antenna, a smaller 4.5-m telescope is visible, which is used for measuring the surface of the large dish, using a technique called holography. The same backend is used for holography at Mopra as described on the page for the ATCA.
There is now also a small Mopra photo gallery.
