Are you mistaking the description of the coatings for a petzval design?

4-layer multi-coated achromatic lens

Hi, Where did you buy the scope from? Does it have a manual that describes the lens design?

The 140mm F/5.7, 4 element (two doublets) scope from Vixen with two speed focuser sells new for $1799.00 at OPT. This 150mm Skywatcher scope at OPT is advertised for $599.00.
