Explore Scientific 152mm f/6.5 Achromatic Optical Tube Assembly

 

Explore Air-Spaced Doublet Refractor Highlights…


  • The tube assembly is constructed from aluminum and stainless steel and painted gloss white.
  • Classic Air-Spaced Doublet achromat optics made with Crown & Flint glass
  • 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 required.
  • All models come with a heavy-duty 2" Crayford-style two-speed focuser.
  • The heavy-duty 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. 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 will be under warranty for as long as it is manufactured, plus five years.

 

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 two-speed focuser, a 2-inch 99% reflective, dielectric-coated mirror diagonal, and an 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 Two-Speed Focuser

The Explore Scientific Air-Spaced Doublet AR Series telescopes include a precision 2-inch, two-speed focuser 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-Inch 99% Reflective Dielectric-Coated Diagonal Mirror

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, 99% Reflective, Dielectric-Coated 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.

 

Free Extended Warranty!

Buy a telescope for yourself or give it as a gift, then send in the registration form to receive a free extended five year warranty in the USA!

All Explore Scientific telescopes and telescope accessories are covered under our standard U.S.A. One Year Limited Warranty against defects with proof of purchase, but you can extend this limited warranty to five years by simply filling out the product registration and submit it in within 60 days.

This program is also available to the person who receives your gift of an Explore Scientific telescope. You don't need to give them the purchase receipt, just remind them to fill out the registration and submit it, and we'll take care of the rest.

 

 


 

 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!

 

Explore Scientific AR152 f/6.5 Air-Spaced Doublet with Twilight II Mount, Tripod and Extension

 

Explore Scientific's new TwiLight II Mount and Heavy-Duty Tripod is perfect for scanning for comets, or anytime you want a stable grab-and-go mount for observing the stars or the landscape ahead. The idea here is simplicity, strength, and smoothness. There is no drive, and no alignments. Just attach your telescope(s) and start observing.
