Product description The AR102 102mm Achromatic Refractor Telescope from Explore Scientific features a doublet achromatic lens system which virtually eliminates chromatic and spherical aberrations. This translates to a distortion-free viewing experience with true color rendition across the entire field of view.The scope uses a heavy-duty 2" Crayford-style focuser. Unlike a traditional rack-and-pinion focuser, a Crayford-style uses a steel rod held tightly against the focus tube. This toothless friction system eliminates backlash and enables ultra-fine precision focusing. The combination of aberration-free optics, precision focusing and a fast f/6.5 focal ratio make this telescope ideally suited for wide-field astrophotography and astroimaging.A mounting cradle-ring clamps over optical tube assembly (OTA), and lets the user adjust the orientation and position of the scope relative to the mount to optimize viewing comfort and balancing, while avoiding interference with other equipment. The scope is offered without a mount or tripod, but a Vixen-style dovetail plate makes it compatible with any mount head with a Vixen-style saddle. - Optical Performance
