Description

Explore Scientific AR152 f/6.5 Air-Spaced Doublet Achromat Refractor


 

The AR152 (six-inch), with its larger aperture optics gathers 44% more light over the AR127 (five-inch) model, providing much brighter images and higher resolution. Our 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 8x50 finder scope. You can be confident that the quality and construction of these telescopes will allow heavy use for many years and are backed with a transferrable Five Year USA Limited Warranty.

 

It's All About the Optics!


 

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.

 

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.


On those prestine 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 refractors 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.

 

So we included as standard equipment, on all Explore Scientific AR Series, 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.

 

Universal Mounting Plate


 

The Universal Adjustable Mounting Plate of the AR 152 fits on many popular equatorial and Altaz 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" 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.

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.

 

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.

    Comments about Explore Scientific AR152 f/6.5 Air-Spaced Doublet Achromatic Refractor Telescope:

    My order arrived a day early and was packaged perfectly. The explore scientific AR 152 arrived and appeared as though it was handled with kid gloves so to speak. Great service from telescopes.com and in a competitive market these folks appear to go the "extra mile" regarding customer service. I will definitely give them my business in the future.

      Comments about Explore Scientific AR152 f/6.5 Air-Spaced Doublet Achromatic Refractor Telescope:

      This scope has a very soild build, with a very smooth focuser. It is also very nice to find a good finder scope on a $700 refractor. The scope rings are very well made. Its also good to see that Explore Scientific owner Scott Roberts listen to the visual astronomers and made sure that all scopes now have a longer dew sheild.
      Over all, this scope is well worth the money. The optical quality is the best I've seen in an Archromat in many years. The coatings on the objective are deep green.
      With build quality and optics as good as this scope has,it should be selling for a lot more money.

      Service and delivery comments:

      Delivery was very fast, and the scope arrived in good condition. The people at Telescopes.com are tops in my book.

      Comments about Explore Scientific AR152 f/6.5 Air-Spaced Doublet Achromatic Refractor Telescope:

      I have always had the itch for a big refractor. I have several Schmidt-Casegrain and they have a lot to offer for their size and weight. But even the best lack the crystalline sharpness of a good refractor. I have a 102mm Celestron XLT refractor which provides clear, crisp images. But it lacks the ability to gather enough light for the more interesting deep-space objects. Thus, I have been on the look-out for a big refractor for some time.

      I have read numerous positive reviews of Explore Scientific products and especially of their customer service. I wander through the product listings of various astronomy products web sites very regularly. When I arrived at telescopes.com I received a pop-up with a coupon code for an additional 5%. You know, that's something I really don't mind! 5% isn't huge but it is something I don't get anywhere else. That coupled with the usual free shipping had me feeling that it was time.

      There are several large refractors available. But the included options and specifications attracted me. The Explore Scientific AR152 is nicely balanced between rich-field and longer, high magnification units. It comes with an excellent finder scope, strong, heavy-duty rings and a silky smooth dual-speed crayford type focuser. It also has a wonderful built-in handle that is really useful. Topping it off is a well-made, excellent quality 2" diagonal. Adding up the pluses I was hooked and ordered one.

      A few days later, our beautiful, young FedEx lady (not kidding - she's a knockout) brought me an impressively big box containing the AR152. Fortunately, a clear, dark, moonless night was settling in and I had my new scope ready to go on a Celestron Advanced Series CG5-GT in under an hour.

      I'll sum up my viewing experience with the following: the AR152 has a nominal amount of purple fringing. Once I got past that the views where awe-inspiring. Stars were pin-point sharp. Clusters had some real depth to them and I've never seen Jupiter so vividly clear. I am 100% satisfied with my investment and highly recommend the Explore Scientific AR152 telescope to anyone that can deal with its substantial weight (23+ pounds) and size. You'll need a strong mount for it.

        This ia a very good, well made scope for the money.
        That's enough for the scope. Now for the manufacturer: Folks, there is something new in the market...OUTSTANDING SERVICE. I have owned a bunch of scopes and never, have I received such great service. I had to have an issue taken care of and received the scope back in a week, ready to use.
