The Explore Scientific Sidara Essential 102mm is a complete beginner refractor telescope built around the app-guided SkyAssist mount. With a 102mm (4-inch) lens and 660mm focal length (f/6.5), it delivers bright, sharp views of the Moon, planets and brighter deep-sky objects, while the SkyAssist system makes actually finding those objects refreshingly simple.

Using your smartphone, SkyAssist figures out where the telescope is aimed and then guides you to any target you choose — no star-hopping or complex setup, just follow the prompts on your phone and enjoy the view.

Who it's for: Beginners who want a well-rounded, easy-to-use first refractor with smartphone help finding objects. New to buying a scope? Start with our guide to picking your first telescope.

  • 102mm aperture: a 4-inch lens for bright, detailed views of the Moon and planets.
  • SkyAssist app guidance: your phone helps locate and centre targets for stress-free observing.
  • f/6.5 optics: 660mm focal length balances wide fields with useful magnification.
  • Alt-azimuth mount: simple up/down, left/right motion with no polar alignment.
  • Complete package: optical tube and mount together, ready to observe.

What you'll see: The 102mm lens shows detailed lunar craters, Saturn's rings, Jupiter's cloud belts and four bright moons, and the phases of Venus. Bright star clusters, double stars and the brighter nebulae and galaxies are all within reach, especially under darker skies.

How does SkyAssist help me find objects?
Your smartphone determines where the telescope is pointing and guides you to any target you select, so no charts or experience are needed.

Is this a good first telescope?
Yes — a capable 102mm lens plus guided object-finding lets beginners get rewarding views right away.

Do I need to polar align it?
No. The alt-azimuth mount uses simple up/down, left/right motion with no polar alignment.

Can I photograph through it?
It's built for visual use; casual smartphone shots of the Moon work well, but deep-sky imaging needs a tracking equatorial mount.
