At those prices a Celestron is competing with the Planewave Instruments CDK 12.5 inch, the Deep Sky Instruments 14.25 RC, a 2nd hand Tak BRC250 with money left over for a mount, a 2nd hand 12.5 inch RCOS with money left over for a mount, a TEC160mm fluorite triplet or a TEC160mm ED with AUD$8000 left over.
For $18K you could get a decent APO, mount and CCD camera or any number of good combos fully setup.
Makes for an easy decision though.
Greg.
