Explore Scientific AR152 f/6.5 Air-Spaced Doublet OTA
Universal Mounting Plate
The universal adjustable mounting plate of the AR 152 fits on many popular equatorial and altazimuth mounts, including mounts supplied by Explore Scientific, Vixen, and Meade LXD55/75. Instead of using a cast metal part, Explore Scientific's universal mounting plate is made from extruded aluminum for added strength, it is afterall what secures your telescope to the mount. We also include adjustment screws and locking bolts to allow adjustments to position the angle of the telescope when it is placed on its mount, an important feature when using an equatorial mount.
2-Inch 99% Reflective Dielectric-Coated Diagonal Mirror
The two inch 99% reflective mirror diagonal includes a 1.25" eyepiece holder adapter. The purpose of a diagonal is to securely hold your eyepiece and to give you a comfortable viewing angle. Provided as standard equipment, Explore Scientific's two-inch, 99% reflective, dielectric-coated diagonal incorporates a light-weight, one-piece diagonal body that securely cradles the precision polished diagonal flat mirror, insuring precision alignment.
8x50 Finder Scope
The Explore Scientific 8x50 finder scope provides a true field of view of 6°. Its coated optics provide a bright high-resolution image so that many faint stars and nebulosity can be detected for precise aiming. The front objective can be custom focused to provide a sharp image every time.
