Refractor 160mm


160 mm is the ‘entry aperture’ into the ‘big refractor’ world.

We deliver it in two packages, one aimed for both visual and imaging work, with 1050 mm focal length, while the 1200 mm focal length should be used for pure visual enjoyment of planets and deep sky objects.

Oil-spaced triplet design starts to show its advantages in these big sizes, helping the triplet lens to quickly reach ambient temperatures.
