I have had it just over a year, bought it brand new through a local SA telescope retailer (Optic SA). No one in Australia can work on it, due to the large airspaced triplet design, it requires specialised equipment. According to Texas Nautical Repair in the USA, it needs a double pass laser collimator or some such sounding instrument. Must admit, it scares the hell out of me having to freight it all the way back to Japan.
