Explore Scientific

Sporting a distinctive large aperture and deep light bucket, the Explore Scientific FirstLight 254mm f/5 Dobsonian Telescope gives users a simple yet highly effective platform. The fast f/5 focal ratio, hexagonal rack-and-pinion focuser, and the ability to detach the OTA from the rockerbox and mount it on an equatorial mount make the FirstLight a good choice for imaging. A Vixen-style dovetail plate is included for use with an EQ mount. The 2.5" focuser allows the use of both 1.25" and larger 2" eyepieces and accessories.The heavy base provides a rock-steady platform with very low vibrations, and can be disassembled into flat sections within minutes for easy transport. Dual mounting rings allow the OTA to be precisely balanced for smooth movement. The telescope comes with a red dot finder, a red-beam flashlight with lanyard, a Tirion Double-Sided Multi-Latitude Planisphere, and a double-sided moon crater map.Optical Tube 254mm (10") aperturef/5 focal ratio1270mm focal lengthOptical Design: Dobsonian-variant of a Newtonian reflectorMount Alt-az rocker designLarge aluminum altitude wheels allow for smooth movement and tracking with reduced vibrationTeflon pads on ground plate enable smooth 360 rotationAdjustable mounting rings enable precision balancing when using lighter or heavier accessories for smoother motionMounting rings allow the altitude wheels to be removed and replaced with included Vixen-style dovetail for attachment to an EQ, alt-az, or GoTo mount head for tripod/pier useFocuser Large hexagonal 2.5" helical rack-and-pinion designProvides strength and rigidity to handle heavy eyepieces and imaging rigs with little backlash, tilt, or shiftingIncludes 2" and 1.25" eyepiece adapters to allow use of a variety of eyepieces and accessoriesIncluded Accessories 25mm SPL eyepieceRed-dot finderAstro R-Lite Red Flashlight with lanyardTirion double-sided multi-latitude planisphereDouble-sided moon crater map
