What make it was,(probably a Tak?) but it didn't hold a candle to my 16' Newtonian.
Reading his article and the comments, to me it came across as a lot of money for a small increase in sharpness.

Well, in another life I was a professional astronomer in South Africa and the observatory had a 26.5" refractor. Great instrument. One night with superb seeing I was looking at Mars with 1000 power. Absolutely amazing clarity and detail. It's something that I'll never forget.
