Explore Scientific 127mm Doublet Refractor with Twilight I Mount
Explore Scientific has paired their ever popular 5" doublet refractor with the portable Twilight II Alt-Az mount. A perfect choice for observing on the go and particularly well suited to public outreach. Complete with a set of accessories to have you ready to observe when you add your choice of eyepieces.
Explore Scientific 127mm Achromatic Doublet Refractor
The 127mm doublet refractor from Explore Scientific features a short f/6.5 focal length, air-spaced crown and flint optical design and dual speed focuser. Fully multi-coated FPL53 optical glass is hand inspected to ensure optimal performance. Each telescope is carefully collimated before leaving the factory and you may never need to adjust the collimation of your scope. In the case that your Explore Scientific refractor does need adjustment, a specalized collimation lens cell will allow you to make any fine tuning adjustments needed. Contrast is enhanced with multiple tube baffles that deter stray light from reaching your eye.
Included with your Explore Scientific 127mm is a 10:1 dual speed focuser. This 2" focuser offers both coarse and fine focus adjustment and includes a 1.25" eyepiece adapter with compression ring to securely hold your 1.25" or 2" eyepieces in place. A tension adjustment will help lock focus in place avoiding constant need for focus adjustment.
Comfort when observing is key, as is maintaining optical integrity. For these reasons, Explore Scientific has included a 2" dielectric star diagonal. This lightweight diagonal won't weigh your telescope down. The one piece body holds a precision coated 99% reflectivity flat mirror.
To help you find your target, an 8x50 optical finder has been included. With a true field of view of 6 degrees, coated optics provide a crisp and bright image in high resolution.
To attach your 127mm doublet to the Twlight mount, Explore has included a set of tube rings and a V series mounting plate. Made from extruded aluminum this dovetail is strong and will stand the test of time (and pressure!). Adjustment screws and locking bolts give you the power to adjust the angle of your scope, particularly helpful if you'll be using this telescope on an EQ mount.
Explore Scientific Twilight I Alt-Azimuth Mount
Explore Scientific's Twilight I mount is a capable of carrying loads up to 18 lbs. A perfect choice for medium to lightweight short refractors, this is the ultimate grab and go mount. A powder coated aluminum head for strength and stability and with worm gears on both axes, movement and adjustments are smooth and precise. Slow motion control cables with over-sized knurled knobs are included for both vertical and horizontal adjustment. A handy mini-wrench is stored on the fork arm by a magnet to allow for quick adjustments in the field. A chrome-plated steel tripod comes standard with the Explore Scientific Twilight Alt-Az mount. Adjustable lgs and a 42" wide footprint provide necessary stability and a spreader bar locks it all in place keeping vibrations at bay.
