Home Telescopes SkyWatcher Telescopes SkyWatcher Apo Refractors Skywatcher Esprit 150 ED PRO Triplet Super Apo Refractor
Extraordinary telescopes with premium optics and mechanics, the SkyWatcher Professional ESPRIT 3 Element ED apochromatic refractors are designed to be the ultimate in this price range. These are instruments of the highest quality with optical performance rivalling or exceeding similar telescopes of even the most famous high-end telescope brands. The optical design uses only the highest gradse of glasses available, this combined with a very robust and quality tube assembly results in a very fine instrument that will satisfy even the most discriminating user.The 3" diameter linear focuser performs superbly for imaging or precise focusing visually - avoiding the often costly exercise of focuser upgrades we see so often on lesser models, a remarkable acheivement of optical and mechanical engineering available at an equally remarkable price.
The ESPRIT Super Apo Triplets are designed for the most demanding astro-imagers but are also fine telescopes for visual observations often outperforming telescopes far larger of lesser designs. The premium, superbly-corrected optical systems deliver high-contrast images full of detail with pin-point stars right up to the edge of the field and zero detectable colour fringing, even on the brightest of objects resulting in true Apochromatic images.Features: 3-Element Objective Lens F7, Focal Length 1050mm (one Ohara FPL-53 and 2 x Schott lenses) 3" CNC Machined 11:1 Rotatable Dual-Speed Linear Power Focuser Full-frame Corrected Focal Plane Excellent Field Flatness Zero detectable Colour Fringing even on Bright Objects Metallic High-Transmission Lens Coatings Knife-edge Baffled Optical System High-precision Mechanical Components Aluminium OTA material (superior to plain carbon-fibre for this application) Retractable Dew ShieldDual Speed Linear Focuser: 3" LPF with 2" and 1.25" eyepiece adaptors and indexed scale Zero focus-shift during focusing High Load Capacity - holds up to 5kg of accessories whilst focusing and up to 10kg when locked.
