150mm 4 lens skywatcher refractor

i still can't find any lit. on it even at skywatcher site! roland christen says it can have 4 lens if normal glass. i hope not,it will probably suck,only paid 599.00 . even spec sheet at opt. says 4 lens achromat.

On Skywatcher website it appears that they have the Synta made 150mm achro with 1200mm focal length. They call it F/8.3 scope???? It should be 1200/150 or F/8 (bad math????)

They also say "4-layer multi-coated achromatic lens" and "Professional-class instrument, allowing serious research of the planets"
