Newtonians

A Newtonian reflector gives you more aperture for your money than any other design. One parabolic mirror, one flat secondary, no colour fringing and a short focal ratio that suits both visual observing and fast imaging. Many experienced astronomers keep one alongside their other telescopes.

Our Newtonians range from beginner kits like the Celestron AstroMaster and Explore Scientific FirstLight to precision British-made tubes from Orion Optics UK (VX, IDEAL, CT and AG), plus imaging Newtonians from Sky-Watcher Quattro, iOptron, SharpStar HNT and Askar. For Newtonians on a rocker base, see our Dobsonian collection.

Visual and Imaging Newtonians

  • Visual tubes at f/4.5 to f/6: Comfortable to collimate, forgiving of eyepieces and sharp on planets. Orion Optics UK VX and IDEAL, Celestron kits.
  • Long-focus L versions: Orion Optics UK VX L and IDEAL L tubes run around f/6 to f/8 for higher magnification and a smaller secondary.
  • Imaging Newtonians at f/2.8 to f/4: Sky-Watcher Quattro, iOptron f/4, SharpStar HNT and Orion Optics UK AG. They need a matching coma corrector and a strong focuser.
  • Carbon tubes: Orion Optics UK CT series. Carbon expands very little with temperature, so focus stays put as the night cools.

Collimation Is Part of the Deal

Newtonians need occasional collimation, especially after transport. It takes a few minutes once you have done it a couple of times. A good collimation tool makes it quick and repeatable.

What We Look at With You

  • Focal ratio and use: An f/4 imaging tube is harder to collimate and needs a coma corrector. An f/6 tube is easier and sharper for planets. We help you choose between them.
  • Mount for a long tube: A 10-inch Newtonian acts like a sail in the wind. We size the mount for the moment arm as well as the weight.
  • Corrector and spacing: For imaging tubes we name the coma corrector and the back-focus to set.
  • Focuser upgrade: Heavy cameras on a stock focuser cause slip and tilt. We say when an upgrade is needed and when it is not.

Newtonian Telescopes: Frequently Asked Questions

How often do I need to collimate?

Check it each session with a quick look through a Cheshire or laser. Small adjustments are needed after transport, rarely otherwise.

Are Newtonians good for astrophotography?

Excellent, if the tube is designed for it. Imaging Newtonians have a larger secondary, a focuser that reaches camera focus and a coma corrector.

Why are the Orion Optics UK tubes more expensive?

Their mirrors are made in-house in the UK and specified to a stated wavefront accuracy, with optional higher grades. The difference shows at high power on good nights.

Want the most aperture for your budget?

Tell us how you will use the telescope and how you will transport it. We will recommend a tube and mount.
