Description

Explore Scientific AR102 f/6.5 Air-Spaced Doublet Achromat Refractor


 

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 the price of comparable aperture apochromat refractors. Finally one can own a diffraction-limited high quality refractor for a relatively modest investment.

 

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 102 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 AR102 f/6.5 Air-Spaced Doublet Achromatic Refractor Telescope:

      Well, I purchased this scope because I wanted a refractor that I could use at home for when the moon is up and I wanted to go Double Star hunting. Well, I have had the scope out twice in my backyard and I am very happy with my purchase. On the first outing I was able to see the Cassini Division on Saturn's Rings and two bands on Saturn. Leo 54, a double star in Leo was magnificent the first night out showing a gold and bluish companion. M65 and M66 in Leo were visible. M13 in my 7mm Pentax XW was wonderful!

      The second outing I focused on lunar observations and did a sketch using the scope that I actually liked. I found it easier to move the AR102 on a Twilight I mount (from Explore Scientific that I purchased here) than my 10 or my go to scope, my 14 inch dob. I looked at Regulus, Algebia, Mizar, two other doubles in Ursa Major; M51 and its companion showed! Finally I did the double double in Lyra and ended with Alberio and Saturn.

      Pros of this scope are its ease of use. The two speed focuser is really nice, and I like the handle also. It is much larger thanks to the dew shield on the end. The straight through finder will work, but I must have a 9x50 RACI on it and since I have an extra, yep, its on there. Makes it much easier when one goes to zenith or in that part of the sky. Oh, I did purchase a filter to get rid of the violet and green from the scope when looking at the moon and bright objects like planets. I had anticipated that so I was content to have the filter. I can see many a non new moon nights now for a couple of hours being spent in my backyard using this scope. That and I just might redo the Messier objects with it and sketch it one again.

      Last note. If you are buying this for deep sky objects in a suburban area, be careful. You need a train eye to see and capture many of the brighter DSO's in this scope. You can do it, but you have to kinda of know what to look for or be out when the moon isn't up. You can do it, just be warned it is not like looking at DSO's through a 8 inch or 10 inch dob in your backyard. For me though, I will really enjoy it and I cannot wait to get it to a dark site for some wide field sketching of the Milky Way in Sagittarius, Scorpius etc. What a wonderful scope ES put together here. Oh yea, with the mount, the scope is very easy to transport and set up. Much easier than my ten inch or 14 inch dobs. Don't take me wrong, the 14 inch is my main telescope but this is going to see good use as well.

            Bought as a grab and go scope for educational outreach programme's......I do own both a 80 mm / 100mm TMB APO which I consider both superbly crafted instruments .....optically near perfection...

            The incredible shock!!!!!!
            first light was last year......I was taken aback at the razor sharp images of the lunar surface....contrast
            was comparable to scopes costing twice as much.....Jupiter revealed distinct festoons, barges , and a
            spectacular view of the GRS ... Jupiter's moons were distinct and revealed a radiant disc ....

              Carry handle and dovetail included with the rings is a nice touch.
              As is the 2 inch focuser and diagonal with compression rings instead of set screws.
              Focuser is also much better than what you would expect with a factory scope. Tension adjustable and lockable.

              Only complaint I have is the finderscope. It's GOT to be replaced with a right angle scope. I'd rather this one not be included at all.

                Spectacular views! Very well made! Great value for the price! - I use it with my Baader Hershel Wedge that I bought from Telescopes.com. I'm 65 years old and after 40 years of buying telescopes, this scope beats them all, hands down! Buy this unit ASAP! Great value for the money! More so, do not hesitate on buying anything from Telescopes.com. Fast shipping! Great customer service! Honest descriptions! BETTER THAN DESCRIBED!!!
