Explore Scientific AR127 Air-Spaced Doublet Achromatic Refractor Optical Tube Assembly

AR127 Air-Spaced Doublet Refractor Highlights…

- 127mm f/6.5 design.

-The tube assembly is constructed from aluminum and stainless steel and painted gloss white.

-Classic Crown & Flin Air-Spaced Doublet achromat optics.

-Research-grade, diffraction limited surfaces.

-Enhanced Multi-Layer Coatings (EMD) are deposited on optical elements to boost contrast and eliminate light scatter.

-While refractors seldom require additional collimation after initial factory adjustment, the lens cell design allows for consumer collimation. Sending off to the factory is an option, but is not required.

-Come with a heavy-duty 2" two-speed focuser.

-The light-weight 2" diagonal has 99% dielectric coatings for high contrast, bright images. A 1.25" compression ring adapter is included.

-Includes an 8x50 straight-thru finderscope with a wide 6° field of view, with front objective focus.


Optical Alignment

One of the bonuses of ownership of a refractor is that, compared to standard reflector telescopes, they almost never require re-aligning of the optics (collimation). However, any telescope that is subjected to shock may require optical alignment.

Removing the dew shield, you can access the alignment screws, which you can adjust yourself by referring to the instructions. You can also send it to Explore Scientific’s Service Center for alignment. A standard service charge applies.  

Viewing Comfort and the Preservation of Precious Light

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 Dielectric Diagonal incorporates a light-weight, one-piece diagonal body that securely cradles the precision polished diagonal flat mirror, insuring precision alignment. Ultra-high reflective coatings (99% reflective) composed of multiple thin layers of dielectric material delivers maximum light output.

Both 2" and 1.25" eyepiece holders use compression rings instead of a simple set-screw to more securely hold your valued eyepiece (or imaging device) and to minimize scoring of eyepiece barrels. You can thread standard 48mm filters into the barrel.

Many premium small refractors don't include some basic accessories like a viewfinder. This is often done to keep prices down. Those manufacturers rationalize that its owner simply will not need a viewfinder... wrong!

The Explore Scientific 8x50 produces a wide 6° field of view and allows precision focus of both main objective and eyepiece illuminated reticle. A precision polished roof prism produces images that are right-side-up, left-to-right correct. In other words, things are not upside-down and backwards like most viewfinders. Our illuminated reticle is truly designed for finding objects with its open center (so you don't mask the object you are centering with cross hairs) and scale markings for 1.5°, 3°, and 4.5° (the edge of the field of view is the 6° boundary).

The 55° apparent field, long eye-relief eyepiece produces a bright 15.5mm exit pupil and will allow you to find faint galaxies, comets, and nebulae. All optics are fully-multicoated to insure maximum contrast.  

Universal Mounting Plate

The Universal Adjustable Mounting Plate of the ED 127 fits on mounts supplied by Explore Scientific, Vixen, and Meade LXD55/75. It also attaches to photo tripods with standard USA or European thread attaching knobs.

You can mount the ED 127 to many popular equatorial and Altaz mounts, including Explore Scientific mounts.  

Free Extended Warranty!

 AR Optics in Adjustable Cell

It's all about the optics! The Crown & Flint optical elements used in the AR Doublet Series telescopes 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.

As a privilege of ownership, those who wish to obtain a copy of their Air-Spaced Doublet Series interferometric data can request it 90 days after registering the warranty of your telescope by contacting our Customer Service Department.

 

 

 Explore EMD Coatings

EMD (Enhanced Multi-layer Deposition) Coatings eliminates light scatter and maintains high image contrast. This proprietary coating is applied to all Explore Scientific lenses in multiple layers for added durability.

Contrast is further enhanced with multiple knife-edge baffles in the optical tube that mask and deflect unwanted stray light.

 

 Deluxe Two-Speed Focuser

The Explore Scientific AR102, AR127, and AR152 Air-Spaced Doublet Refractors include a high quality precision 2" dual-speed Crayford-style focuser with 10:1 micro focus and tension adjustment. The ability to adjust and lock the tension on the draw tube is helpful when you change the weight of the load.

You will appreciate the smooth movement, the large course and fine focusing knobs, and the graduated scale imprinted on the draw tube. A 1.25" compression ring eyepiece adapter is included.

 

 

The Critical Element: Optics

Designing and manufacturing optics is at the heart of what we do. Explore Scientific designers and optical craftspeople constantly strive to produce optical tools that will deliver the precision and dependability that explorers of the Universe deserve, regardless of their level of expertise.

Producing optics of this caliber requires a solid design, careful fabrication, and multiple tests throughout the manufacturing process, but it also takes a dogged determination to keep perfecting our processes and skills so that our products keep getting better and better. To further insure your faith in Explore Scientific products, we back all of our telescopes with the Explore STAR Transferrable, Extended Life of the Product Warranty, so you can keep exploring!
