AP 152 starfire F9 1992 production.....

Hello guys, anybody use or own that model scope??
is the 3 elements from AP air spaced produced in early 90'

i'll be very pleased if you could give me further informations about color correction in spite new model and of course about range price on used market.

many thanks, Christian

The 1992 catalog describes the 155mm F9 EDT color
correction as "less than 0.01% focus variation from
706nm to 405nm." The later 155mm F7 EDF model had
the same specification.

Average selling price shown on telescopebluebook.com
is $3700 for sales after 2001.

Heres a spec sheet attached.

The 152 F/9 is really not an apo but it is darn close, more importantly it is an AP, it is a vast improvement over the earlier 6" F/8 series but nowhere near the perfection of 155 F/9EDT which in my opinion is the best 6" visual apo that AP has produced to date.
