Why this gift works

The Celestron NexYZ Smartphone Adapter (item 81055) clamps a phone behind the eyepiece of a telescope, spotting scope, binocular or microscope. Three knobs move the phone on three axes to center its camera over the eyepiece, and it rotates for portrait or landscape. It fits eyepieces 35 to 60 mm across - down to 25 mm with the included adapters - and phones 65 to 90 mm wide, and it is made of cast metal and fiber-reinforced plastic, 10 ounces in all.

Holding a phone to an eyepiece by hand is frustrating; this holds it steady so the Moon's craters fill the screen. Celestron pitches it as a first step into astroimaging - a way to share the view, not a replacement for a dedicated astronomy camera.

Who is this gift for?

Great for

  • A telescope owner with a good phone camera
  • Moon and planet snapshots
  • Showing friends what they saw

Think twice if

  • They do not have optics yet
  • Their phone is wider than 90 mm

The catch

Bulky phone cases may have to come off, it adds 10 ounces at the eyepiece end of the scope, and phones wider than 90 mm will not fit.

Skip if they do not own a telescope or binoculars yet, or already shoot with an astronomy camera.

What to look for in a telescope phone adapter
