The Explore Scientific AR152 is a large 152mm (6-inch) achromatic refractor telescope built for bright, high-contrast views of the Moon, planets, and brighter deep-sky objects. A refractor gathers light through a lens at the front of the tube, giving crisp, low-maintenance views. At f/6.5 this is a fast, wide-field 6-inch that still delivers plenty of resolution and reach. This listing is the optical tube assembly (OTA).

Who it's for
Intermediate observers who want a big-aperture refractor for planetary detail and wide-field deep-sky views. Comparing scope types? See our refractor vs reflector vs Dobsonian guide.

  • 152mm aperture: a 6-inch objective that gathers plenty of light for bright, detailed views.
  • 988mm focal length (f/6.5): a fast focal ratio for wide, immersive fields.
  • Air-spaced doublet achromat: crisp, high-contrast optics that need little maintenance.
  • 2-inch Crayford focuser: smooth, precise focusing for eyepieces and imaging accessories.
  • 8x50 finder included: makes locating targets quick and easy.

What you'll see
The Moon shows craters and mountain ranges in sharp relief; Jupiter reveals cloud belts and its four bright moons; Saturn's rings stand out clearly. The wide 6-inch field also frames big open clusters, bright nebulae, and the brighter galaxies on a dark night.

Does it include a mount?
This listing is the optical tube (OTA). A 6-inch refractor is long and needs a sturdy mount — pair it with a robust alt-az or equatorial mount rated for the weight.

Will I see color around bright objects?
As a fast achromat, some violet fringing can appear on the Moon and bright planets — normal for this design and easily tolerated or reduced with a fringe-killer filter.

Is it good for astrophotography?
It's best suited to visual use and lunar/planetary imaging. For deep-sky imaging, an apochromatic refractor is the better choice.

What eyepieces should I use?
A low-power 2-inch eyepiece for wide fields plus a couple of shorter focal lengths for the Moon and planets covers most observing.
