Hello
I intended to say that the manufactured Aries is a few years ago an objective triplet fluorite 150mm f/d 6
Is this true?
If such were the case, which was the quality and why to have finished the production?
Thank you in advance of your answer.

Didier

Aries is in Ukraine and made in past :

4"F/6 triplet Fluorite
6"F/8 triplet fluorite
6"F/9 triplet Fluorite
7"F/8 triplet Fluorite
8"F/9 triplet fluorite
10"F/9 triplet Fluorite
12"F/10 douplet Fluorite

the only 150F/6 Triplet I know of is the LZOS modell, 5 lenses have been made in total, 2 used Fluorite, 3 used OK4 ED glas. Production was stopped due manufactoring difficulities such lenses that time
