About this product

Designed with the discerning astrophotographer in mind, Sky-Watcher’s top-of-the-line Esprit refractors deliver the kind of imaging performance one would expect from telescopes costing thousands of dollars more. With Esprit’s three-element, air-spaced objective lens design, false color is virtually eliminated, yielding exceptional contrast and sharpness. Each element is fully multi-coated with Sky-Watcher’s proprietary Metallic high-transmission Coatings (MHTC)™, producing a transmission rate that rivals any refractor on the market. 

In addition to superb optics, all Esprits feature exclusive dual-speed, Helinear track focusers, which provide smooth, rock-solid focusing with zero image shift. Using a captain’s wheel design all focusers can be rotated, giving astrophotographers flexibility when framing their image. 

As is customary, Sky-Watcher supplies everything you need to get out under the stars, including a 2-element field corrector, which guarantees a flat field across the entire imaging plane. All Esprit refractors also come with an 8x50 right-angle finderscope, 2-inch star diagonal, M48 camera adapter, mounting hardware, and padded case.

Back to Astronomy and Astro Photography

This telescope was my way of getting back to astronomy and astro photography after a lapse of about 40 years when things were done with film and DIY reflecting telescopes, 8 and 6 inch being the norm. Any refractor scope of more than 3 inches aperture being totally beyond reach because of cost. My how things have changed with the cost of quality equipment and the digital age so I decided to make sure that I took advantage of what I considered a better than good all round option and my choice was this Skywatcher SEPRIT ED Triplet APO Refractor scope and I have not been disapointed with my choice. I've only had three nights of use and have taken the best shots of the moon ever, the Orion Nebula in all it's glory with only a few seconds exposure and the Horse Head nebula, also in Orion, considered to be a difficult subject as a real test for this instrument. The clarity of the images and the triple APO lens with absolutely no colour fringing, over the entire flat field was up to spec as one would expect from such a instrument. To get this sort of performance some 40-50 years back one would have to have a 6 to 8i inch object glass refractor to match and even then it would probably suffer from defects. Great scope. Well engineered, Top kit. To get the best one must also invest in a high end mount, goto if poss, and for astro imaging at least a suitable DSLR camera or better still purpose built astro camera's. I went for the ZWO equipment but there are many options to choose from. My the skies be clear.
