Refractor 102 - 105 mm

Availability: manufactured on request; Type: refractor

We began manufacturing the F/6 version in 2013, looking to create a portable refractor, aimed at travelers who seek airline portability with maximum aperture. We warmly recommend it for visual & imaging astronomy, birds & other wildlife observing & imaging, eclipse chasers.
With 102mm aperture, versions with 915 mm or 1050 mm focal length, feature a Strehl ratio > 0.95, from 430 to 700 nm; as such, these will render planetary images with highest color fidelity/resolution, limited only by aperture & local seeing conditions.

* 3(three) different focal lengths to choose from; (subject to availability)
