Quantum Six

As the story goes, back in 1976 a company was formed to produce high quality Maksutov Cassegrain telescopes at a price that many amateurs could afford.  Advertisements were very informative and compelling so by 1978 I placed an order for my own Q 6.  Delivery was about one year later.  Since that time the telescope has been a pleasure to own.

Less than 300 Quantum Six telescopes were produced.
