Explore Scientific AR127mm f/6.5 Air-Spaced Doublet Refractor - DAR127065-02

Introducing the Explore Scientific AR127mm f/6.5 Air-Spaced Doublet Refractor Telescope - DAR127065-02.

This telescope is a modern take on the classic air-spaced doublet design, offering superior optical quality with its short f/6.5 focal length.

Enjoy stunning celestial views without the high cost of an apochromat refractor.

Built to withstand public star parties and educational outreach, the Explore Scientific AR Series telescopes feature robust components.

These include a 2-inch dual-speed focuser, a one-piece 2-inch diagonal with 99% dielectric coatings, an Explore Scientific Hybrid Finder Scope Base with an 8X50 non-illuminated finderscope, and a quick-release bracket.

The telescope also comes with a cradle ring assembly equipped with a Vixen-style dovetail mount for easy mounting.

Simply add your preferred eyepieces and choose an alt-azimuth or equatorial mount, and you'll be ready to embark on a journey of celestial discovery.

After 120 days of ownership, you can request interferometric data for your registered Explore achromatic refractor from Customer Service.

Great Value

This scope produces clear views with a wider field of view than my smaller refractor (80mm). The only thing I need to do is upgrade my Eyepieces (I’ll probably look at getting some 80 degree ES eyepieces). This should allow for even better views. The craftsmanship of this scope is fantastic. Keep in mind, it is a fairly large Telescope, but I find I can still move around comfortably with it. The finder scope is also quite handy (it comes with the Telescope, so it won’t need to be purchased separately, which is convenient). Happy stargazing!

High quality at an affordable price

This telescope is an excellent choice in this price range. Quality assembly from Explore Scientific once again. Focus adjustment is very important to me, this Telescopes delivers.
