An internet search fails to uncover any news concerning this type of scope, and the Esprit 150 APO is a f7 triplet using FPL-53 glass.
Is this simply an advertising mistake in describing the Esprit or is there actually a 150 m f8 APO coming as well (maybe a Doublet version)?
Keeping my fingers crossed then Glen..As a predominantly visual observer of Doubles,Planets and planetaries, a good doublet Apo would do me ..with good glass at F8..otherwise I may very well get a TS scope or APM..There all fabulous these days and a test report above .95 Strehl included by Marcus Ludes !
