About Explore Scientific AR102

The Classic air-spaced, crown-and-flint, doublet achromatic refractor is reborn with the aim to produce superior-class optical figure in a short (f/6.5) focal length design with Explore Scientific Air-Spaced Doublet AR Series. These optics are an extreme value, produce stunning images of deep sky objects, double stars, planets and the moon that are a small fraction of comparable aperture apochromat refractors.

Designed to handle the rigors of public star parties and educational outreach, the Explore Scientific AR Series has standard hardware which includes a precision 10:1 two-speed focuser, a 2-inch diagonal and 8x50 finder scope. You can be confident that the quality and construction of these telescopes will allow heavy use.

Explore Scientific AR102 Features

  • The optics in the collimatable lens cell are fully multi-coated to eliminate light scatter and maintain image contrast. Explore Scientific precision collimate every Explore Scientific telescope at factory to give optimum performance
  • Contrast is further enhanced with multiple baffles that mask and deflect unwanted stray light
  • Deluxe 10:1 Two-Speed Focuser: The Explore Scientific Air-Spaced Doublet AR Series telescopes include a precision 2-inch ten-to-one, two-speed as standard equipment. The eyepiece holder uses a compression ring to prevent the eyepiece or camera barrel from scoring
  • Universal Mounting Plate: The Universal Adjustable Mounting Plate of the AR 102 fits on many popular equatorial and Altaz mounts, including mounts supplied by Explore Scientific, Vixen and Meade LXD55/75
  • 2" Diagonal Mirror: The Two Inch 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
  • 8x50 Finder Scope: The Explore Scientific 8x50 Finder Scope provides a true field of view of 6deg.. Its coated optics provide a bright high-resolution image so that many faint stars and nebulosity can be detected for precise aiming

It's just OK.


from Little Chute, WI  -  Casual/ Recreational

I'm a little disappointed with the finish quality of this telescope. The black piece that goes around the end of the dew shield looks like it had a bad glue job by whoever put it on. The finish of the painted tube is a little bumpy here and there where it clearly should be smooth like they had gotten a little dirt on the outside of the scope while painting it. Things like this make me question the quality of the rest of the scope. I've used it a few times now. The dove tail is painted so it will get marked up when it's put on the mount. The focuser feels smooth and does not go out of focus easily. There is a significant amount of CA on Jupiter, however the moon looks good. All in all, It's not bad for the price. Would I recommend it? Meh. Probably not. I'd probably tell someone to spend another $300 and get something you'll be happier with.
