The optics use a center lens element of Hoya FCD1 (Dense Fluor Crown) glass, the Hoya equivalent of FPL-51 ED (Extra-low Dispersion) glass. This ED element produces superior sharpness and color correction by minimizing the chromatic aberration, the \"false\" color fringing seen around bright objects when light rays pass through standard crown-and-flint doublet objectives.

However, any air-spaced refractor telescope may require optical recentering if the lens elements are knocked out of alignment by a heavy blow during shipping or use. Removing the dew shield will give you access to the lens centering screws in the sides of the lens cell, which you can then adjust yourself by referring to the supplied instructions. You can also send your scope to Explore Scientific's Service Center for precision alignment. A standard service charge applies for factory realignment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDew shield:\u003c\/strong\u003e The supplied removable 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. A single thumbscrew holds the dew shield in place, allowing the felt-lined dew shield to be removed from the scope, reversed, slid back onto the optical tube, and stored for transport in only a few seconds. The optical tube measures a compact 18.5\" long, including the dew shield. A thread-in metal dust cap for the optical tube is standard.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDual speed 2\" rack and pinion focuser:\u003c\/strong\u003e The precision-made no-backlash focuser has dual-speed focusing. There are two coarse focusing knobs. The right knob also has a smaller concentric knob with a 10:1 reduction gear microfine focusing ratio. 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.\u003c\/p\u003e\n\u003cp\u003eThe focuser drawtube has a scale marked in centimeters and 1mm increments. This lets you note individual focuser positions for easy return to the correct focus when switching between visual use and photography. Two knobs underneath the focuser lets you adjust the tension on the drawtube to accommodate varying eyepiece\/photo accessory loads, as well as firmly lock in a photographic focus. The focuser has a non-marring 2\" brass compression ring equipment holder.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2\" dielectric star diagonal and compression ring eyepiece holders:\u003c\/strong\u003e The supplied standard equipment 2\" mirror star diagonal of the ES80CF slips into the focuser drawtube's 2\" eyepiece\/accessory holder. The 2\" diagonal has 99% reflectivity dielectric mirror coatings for high light transmission. The star diagonal uses a non-marring soft brass compression ring to hold 2\" eyepieces in place. The compression ring won't scratch the barrel of your 2\" eyepieces as an ordinary thumbscrew can.\u003c\/p\u003e\n\u003cp\u003eA supplied 1.25\" accessory adapter slips into the 2\" diagonal to let you use 1.25\" eyepieces in the 2\" diagonal. The 1.25\" accessory adapter can also be inserted into the 2\" accessory holder on the focuser drawtube to let you use a 1.25\" image erecting diagonal, or 1.25\" photographic accessories. Like the 2\" eyepiece holder on the diagonal, the 1.25\" adapter also uses a non-marring soft brass compression ring to hold 1.25\" star diagonals and accessories in place.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMounting foot:\u003c\/strong\u003e For serious astronomy and astrophotography, the ES80 has an L-shaped dovetail mounting foot that is shaped to fit directly into the Vixen-style dovetail slot on the head of many of the most popular light to medium capacity altazimuth mounts and Celestron VX Series go-to German equatorials, among others. In addition, the dovetail has both 1\/4\"-20 and 3\/8\" holes that allow you to mount the 7.5 pound scope (when including diagonal) directly onto any good photo tripod for casual astronomy or daytime terrestrial observing. A knob on the body of the scope allows you to rotate the tube assembly and focuser to line up a camera in either a landscape or portrait orientation (or any orientation in between), then temporarily lock the focuser in that position.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExtended lifetime warranty:\u003c\/strong\u003e This individually serial numbered Explore Scientific telescope is

Removing the dew shield will give you access to the lens centering screws in the sides of the lens cell, which you can then adjust yourself by referring to the supplied instructions.

However, any air-spaced refractor telescope may require optical recentering if the lens elements are knocked out of alignment by a heavy blow during shipping or use. Removing the dew shield will give you access to the lens centering screws in the sides of the lens cell, which you can then adjust yourself by referring to the supplied instructions.

A single thumbscrew holds the dew shield in place, allowing the felt-lined dew shield to be removed from the scope, reversed, slid back onto the optical tube, and stored for transport in only a few seconds.

In addition, the dovetail has both 1\/4\"-20 and 3\/8\" holes that allow you to mount the 7.5 pound scope (when including diagonal) directly onto any good photo tripod for casual astronomy or daytime terrestrial observing.
