Explore Scientific 102MM F/6.5 Achromatic doublet refractor telescope
The classic air-spaced, crown-and-flint, doublet achromatic refractor is
reborn with the aim to produce superior-class optical figure.
About Explore Air-Spaced Doublet RefractorsThe Explore Scientific AR Series telescopes are classic air-spaced,
crown-and-flint, doublet achromatic f/6.5 refractors with a
superior-class optical figure. Whether you choose the AR102 (4"), AR127
(5") or AR152 (6") model, you will be impressed by the stunning images
revealed to you at the eyepiece, and all at a small fraction of the
price you'd pay for a comparably sized apochromat refractor.
to handle the rigors of public star parties and educational outreach,
the Explore Scientific AR Series telescopes come with heavy-duty, high
quality components, including a 2" dual-speed Crayford-style focuser, a
one-piece 2" diagonal with 99% dielectric coatings, an 8 X 50
finderscope and quick release bracket, and a cradle ring assembly with
Vixen-style dovetail mount. Just add a few eyepieces and the
alt-azimuth or equatorial mount of your choice and you'll be ready to
discover the Universe!

Research-grade, diffraction limited optics.
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

Includes an 8x50 straight-thru finderscope with a wide 6° field of view. The front objective is focusable.
To attach your Explore Scientific Air-Spaced Doublet
telescope to a variety of mounts, we have included an extra strong
extruded aluminum Cradle Ring Assembly and Universal Adjustable Mounting
Plate. The "Vixen-style" plate fits mounts made by Explore, Meade,
Celestron, Vixen & others.
All Explore Scientific products come with a STAR
Extended-Life-of-the-Product Warranty. Upon registration, this product

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.

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
