Observing Kit

Your telescope’s night, planned.

For binoculars and telescopes: it plans your night, keeps a log of it, and draws each of your own instruments as a circle on the sky.

What it does

  1. My instruments. Your telescopes, binoculars and eyepieces, each a true-field circle on the sky.
  2. Double stars. Which pairs your telescope can split, and the ones well placed tonight.
  3. Variable stars. How they change, and when Algol next dims.
  4. Plan a night. From suggestions and your own list, then tick off what you saw.
  5. My nights. A log of your nights with notes and photos, and a card to share.

Where to find it

Open Explore and tap Observing Kit. Tonight lists the doubles and variables well placed this evening, and the binoculars button on the sky opens My instruments, where you set up your own.

How to get it

The Observing Kit comes with Sky Tools, the pack that also holds the Telescope Catalog, the Night Planner, the Eclipse Explorer and the Sky Calendar's whole year. Each pack is a one-time purchase inside the app, yours forever, not a subscription, with Family Sharing included; Everything is all three packs. If you bought Cosmic Expansion, you already own Everything.
