    The larger 3.5 heliars tend to go for much more money than the 4.5 versions. All 3.5s 15cm and up are not as common as 4.5s and highly desired

    Hi Steven,

    From samples i've seen, the C lens has symmetrical cells, 60mm dia. Little bit shorter focal length than a bona fide euryscope IV #5, and operating at f7.

    It is a euryscope design, or as it has been dubbed here, a "pre-euryscope". Search on the forum for a thread on pre- euryscope lenses started by Steven Tribe and you'll learn all you need to know

    Re: How much a 30 cm heliar should weighs ?

    Measuring the lens glass diameter will also sort out this question quickly. A 60cm heliar has glass that is substantially larger than the 30cm.
