The Explore Scientific ED APO 80mm f/6 Essential with Hex-Focus is the latest iteration of Explore Scientific’s popular 80mm Essential Triplet Apo telescope.  The new Essential Apos are now equipped with the brand new 2.5-inch Hexafoc. The special geometric design of this focuser with a hexagonal tube and the prismatic counterpart enables a rigidity that is unheard of in a focuser in its price bracket. This focuser also includes a 10:1 fine focus reduction. Even heavier cameras and equipment are supported by this focuser without slip or tilt in any potential orientation  – which makes the new Explore Scientific Essential Apos even better for astrophotography. The large 2.5″ diameter also helps to reduce vignetting.The excellent optical system with three high precision lenses and two air gaps contains an optimal combination of the Hoya-made FCD-01 glass with two specially selected partner glasses. The  Explore Scientific Essential optical system and the highly rigid focuser team up to deliver an apochromatic telescope that sets new records in performance for outlay.Building on the success of the original Explore Scientific 80mm Triplet Apo and the Carbon Fibre versions, Explore Scientific now release their best ever value 3-inch telescope: the Explore Scientific ED APO 80mm f/6 Essential with Hex-Focus

The Essential series are “bare bones” versions of the Explore Scientific Apos – they still have the exquisite optics of the original triplets, including Japanese Hoya FCD1 Dense Fluorcrown and Explore’s Special EMD™ enhanced multi-layer coatings on every optical surface for the utmost in colour-free performance and still have the high strength aluminium tubes, internal baffling systems and hyper-blackened edges for the ultimate in contrast.  However, the Essential Series Triplets leave it up to you to provide Finders and other accessories – passing on the savings to you as a result.  

The Explore Scientific ED APO 80mm f/6 Essential with Hex-Focus sports the new Hex-Focuser Rack and Pinion Focusers from Explore, featuring a hexagonal cross section to support a larger loads without the potential for “focuser sag” – and a 10:1 dual speed focus control as standard. In addition to this the optical tube assembly comes with Vixen-profile mounting foot.
