No telescope type has influenced amateur astronomy as radically as the Dobsonian telescope. Before the introduction of this telescope type by John Dobson the vast majority of amateur telescopes were small inadequate refractors on shaky mounts – just good enough to show the polar regions on Mars or the rings of Saturn. Bigger telescopes, like…
The AR152 (six-inch), with its larger aperture optics gathers 44% more light over the AR127 (five-inch) model, providing much brighter images and higher resolution. Our goal was to provide an extreme value by providing true diffraction-limited optics at a price that will allow more people to explore the sky with a wide-field large aperture refractor.…
Highly corrected 127mm air-spaced triplet apochromat (with three lenses) and carbon fiber tube and a 2.5′ high-precision Hexafoc focuser.
The three-lens design of the Explore Scientific ED-Apochromats provides everything an amateur astronomer desires – at a reasonable price. The construction with Hoya FCD001 ED glass has two air spaces and provides a level of correction so superior to the two-lens constructions, that are common in this price class, that you will see the difference…
Highly corrected 80mm air-spaced triplet apochromat (with three lenses) and aluminium tube and a 2.5′ high-precision Hexafoc focuser.
