The Explore Scientific Sidara Plus 150mm is a beginner Newtonian reflector telescope paired with the app-guided SkyAssist alt-azimuth mount. A reflector uses a large mirror instead of a lens, so it delivers a lot of light-gathering aperture for the money — here a generous 150mm (6-inch) mirror with a fast 750mm focal length (f/5) that's excellent for brighter deep-sky objects as well as the Moon and planets.

The SkyAssist system uses your smartphone to work out where the telescope is pointing and then guides you to any object you pick, taking the guesswork out of finding targets for a first-time observer.

Who it's for: Beginners who want maximum aperture for deep-sky views with smartphone help finding objects. Curious how a reflector compares to other designs? Read our guide to refractor vs reflector vs Dobsonian.

  • Large 150mm mirror: a 6-inch aperture that gathers plenty of light for deep-sky detail.
  • Fast f/5 optics: 750mm focal length gives bright, wide views of clusters and nebulae.
  • SkyAssist app guidance: your phone helps locate and centre targets for easy observing.
  • Alt-azimuth mount: simple up/down, left/right motion with no polar alignment needed.
  • Complete package: optical tube and mount together, ready for a first night out.

What you'll see: With 150mm of aperture, expect crisp lunar detail, Saturn's rings and Jupiter's belts and moons, plus much brighter views of deep-sky objects — globular clusters resolving into stars, the brighter galaxies, and nebulae like Orion showing real structure from darker skies.

Why choose a reflector over a refractor?
Reflectors give you far more aperture for your money, so this 150mm mirror shows fainter deep-sky objects than a similarly priced lens-based scope.

How does SkyAssist help me find objects?
Your smartphone works out where the scope is pointing and guides you to any target you choose — no star charts or experience needed.

Do reflectors need maintenance?
Occasionally the mirrors need collimation (alignment) to stay sharp; it's a simple, quick routine once you've learned it.

Do I need to polar align it?
No — the alt-azimuth mount moves simply up/down and left/right with no polar alignment.
