    Used Explore Scientific 152mm f/6.5 Achromatic Refractor with Finder Scope - SOLD

    The Explore Scientific AR152 (six inch) f/6.5 Air-Spaced Doublet Achromat Refractor, with its larger aperture optics gathers 44% more light over the AR127 (five-inch) model, providing much brighter images and higher resolution. The goal was to provide an extreme value by providing true diffraction-limited optics at a price that will allow more people to explore the sky with a wide-field large aperture refractor. Images of deep sky objects are stunning at low powers. At high power the moon and the planets are revealed in sharp, high contrast.

    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 an 8x50 finder scope.

    The optics in their collimatable lens cell are fully multi-coated to eliminate light scatter and maintain image contrast. We precision collimate every Explore Scientific telescope at our factory to give optimum performance. Although you may never need to adjust optical alignment, the AR Series allows for collimating the lens set should the telescope ever require it.

    Contrast is further enhanced with multiple baffles that mask and deflect unwanted stray light.

    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.

    On those pristine nights of steady seeing, Saturn's Rings can forever affect the hearts and minds of almost anyone who lays eyes on them. It's nights like these that astronomers like to set up their refractor telescopes and push the magnification to the limits, not only to see the magnificence of the planet at greater scale but to really test the optical and mechanical quality of the telescope.

    Many telescopes are only supplied with a standard single-speed focuser, you will find that a tiny nudge will throw out focus and turn your night into one of frustration. Now included as standard equipment on all Explore Scientific AR Series telescopes is a ten-to-one, two-speed Crayford-style precision focuser with tension adjustment and lock to obtain and hold perfect focus. We think you'll agree that such precision is worth it.

    The Universal Adjustable Mounting Plate of the AR 152 fits on many popular equatorial and Alt-Az 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, after all, what secures your telescope to the mount. Also included are 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.

    The Two Inch Dielectric 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 Diagonal incorporates a light-weight, one-piece diagonal body that securely cradles the precision polished diagonal flat mirror, insuring precision alignment.

    The Explore Scientific 8x50 Finder Scope provides a true field of view of 6 degrees*. Its coated optics provide a bright high-resolution image so that many faint stars and nebulae can be detected for precise aiming.

    *The front objective can be custom focused to provide a sharp image every time.

    Questions & Answers

    Ask a Question
    • I am looking at this telescope.  What would be an appropriate alt-az (non-computerized) mount for this scope?

      Given that the optical tube weighs in at 15 pounds, you will want a mount that can handle at least 20 lbs. One such mount is the Stellarvue M2 with the Vixen Saddle.

    • I am looking at this telescope.  What would be an appropriate alt-az (non-computerized) mount for this scope?

      Given that the telescope weights 23 lbs, getting something that would be able to support about 30 pounds or more would be a great choice. An example of this would be the Stellarvue M150 Alt-Az mount which can support 45 lbs.

    • Do u sell a case, soft or hard, for the AR152? /Ira 

      Hello Ira, There are a couple of cases that you can use for this telescope. The first one is the Orion Soft Padded Case for Medium Refractors. This will fit the AR152 quite nicely. Another option is to go with the JMI Hard Case for Refractor Telescopes.

    • I am considering purchasing the specific telescope, What would an appropriate EQ mount for this telescope? 

      The Celestron CGEM would be a great match for the Explore Scientific AR152 Refractor.

    • I have a CGEM mount for my 11 SCT, and want to use it for the ES152 refractor. What dovetail attachment is required to mount the ES152 on the CGEM?

      The CGEM mount uses a D-style dovetail plate (4" wide plate, ~3" wide dovetail), which are made by several manufacturers such as Celestron, Losmandy, ADM, and others in various lengths from 7"-21". Please contact us if you have any questions.

    • can I use the ES field flattener and also the reducer/flattener with this scope, I read that they both have a backfocus of 55mm. will the 3" reducer work with this scope does it come with a 2 inch barrel as well?

      You cannot use both at the same time, but they will work one at a time. The reducer does not come with a 2" barrel, although it does come with adapters to connect it to your focuser. Normally with the 152, you would use the 3" attachment for the reducer

    • I have an iOptron EQ45 Dual EQ/AZ mount. I would like to mount this telescope in Alt- Azimuth mode. What else or what kind of dovtail do I need to add to my order for this scope? Thank you?

      I would recommend at minimum a 14" dovetail. This will provide sufficent length for balancing the scope.
