The trio delivers crisp, high-fidelity wide-field images of celestial objects. The views are unmarred by the faint but annoying halo of unfocused violet light (chromatic aberration) often seen around bright stars and solar system objects in other large aperture fast focal ratio doublet and triplet refractors.\u003c\/p\u003e\n\u003cp\u003eThe 80mm Sky-Watcher Esprit triplet utilizes the most modern optical glasses and fabricating techniques to deliver the ultimate in small aperture high-fidelity astronomical observing and imaging. Each lens element is individually inspected for purity and absence of striations and other image-degrading imperfections. Each element is then pitch polished to exacting standards of optical fabrication and performance by highly skilled opticians and tested on an optical laser bench to rigidly controlled optical standards. The result is a high-quality, diffraction-limited optical system performing to the theoretical limits of its aperture - one that will give you years of imaging and visual observing satisfaction.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures of this Sky-Watcher refractor . . .\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApochromatic ED triplet refractor optics:\u003c\/strong\u003e 80mm (3.15\") aperture, 400mm focal length, f\/5 focal ratio.

The dew shield slows the formation of dew on the lens in cold weather to extend your undisturbed observing time. It also improves the contrast, similar to the effect of the lens shade on a camera lens, when observing during the day or when there is excessive ambient light at night, such as a neighbor's backyard security light.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThread-on doublet field flattener:\u003c\/strong\u003e When you are ready for imaging, the Esprit 80mm includes a doublet field flattening lens that can be threaded onto the optical tube to transform your scope into an exceptional wide-field imaging Instrument. Using optical grade glass and multicoatings on all air-to-glass lens surfaces, the field flattener provides sharp, in-focus stars across a large fully-illuminated 33mm image circle that is ideal for most APS-C sensor size DSLR cameras and for CCD cameras using the popular Kodak 8300 sensor. Back focus is 75mm. A Canon EOS camera adapter (the most popular DSLR camera brand for astronomical imaging) is standard equipment. Optional Celestron M48 camera adapters are available for Nikon and Sony\/Minolta Maxxum cameras.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDual speed 2.7\" rack and pinion focuser:\u003c\/strong\u003e The precision-made and mechanically ultra-smooth, backlash-free, rack and pinion focuser has a giant 2.7\" diameter drawtube with a 2\" accessory adapter. This rotatable focuser offers dual-speed focusing and has an engraved focusing scale. There are two coarse focusing knobs. The right knob has a smaller concentric knob with 10:1 reduction gear microfine focusing over the full 60mm focuser travel. This provides exceptionally precise image control during high magnification visual observing and critical DSLR or CCD imaging. The large focus knobs have ribbed gripping surfaces so they are easy to operate, even while wearing gloves or mittens in cold weather. A lock knob lets you adjust the tension on the drawtube to accommodate varying eyepiece\/photo accessory loads, as well as firmly lock in a photographic focus.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2\" dielectric star diagonal:\u003c\/strong\u003e The supplied standard equipment 2\" mirror star diagonal of the Esprit 80mm slips into the focuser drawtube's 2\" eyepiece\/accessory holder.
