Welcome, Oregon Star Party 2024 attendees!

We can’t wait to share an unforgettable week with you under the stars! Let’s build some stargazing binoculars together, Thursday and Friday. All materials will be provided with your registration and you can use your completed binoculars Friday night!

We’ll be building Ember,
our pro 50mm binoculars for night or solar observing

With just a few simple tools, we’ll guide you through every step of building your own stargazing binoculars, an experience you can’t get anywhere else.

What makes Ember so special?

Ultra Comfortable

90 degree angle
and hands-free tripod

Ultra Bright, Wide Views

2” focusers allow 10+ degree views at 7mm+ exit pupil

Zoom in Closer

Change eyepieces for magnifications from 7x - 116x (range depends on the lenses you choose)

Easy Adjustments

Merge both images quickly and easily for different eyes and different eyepieces

2” Filter Cartridges

add UHC filters for nebulae
in seconds with magnets

Upgradeable

Upgrade optics at any time, print new components like a green laser pointer

Immerse yourself
in bright, wide views
telescopes can’t touch

Analog Sky stargazing binoculars are the only binoculars designed from the ground up to be pointed at the night sky. If you’ve never seen the sky through binoculars with 2” eyepieces, you’ve missed 1000 unforgettable sights.

And if you’re new to stargazing, there’s no better way to learn the night sky.

Summer Milky Way
from the Eagle to the Lagoon!

Large DSO’s at their very brightest!

Faint DSOs like the Heart and Soul invisible to telescopes

Have you ever wished you could see Barnard’s Loop, the Angelfish Nebula, the Heart and Soul, the California Nebula, or the Cocoon Nebula together with the full Barnard 68 dark nebula? These are just a few of the huge DSOs you can only enjoy through binoculars with maximum exit pupil and 2” nebula filters. And you’ll never see vast starfields like the Sagittarius teapot steam or Scutum the same way again.

With Ember, you can see all these and more, then zoom in for grab-and-go views of the planets, the Moon, and the whole Messier catalog.

Learn real telescope building skills over two days! Install mirrors and lenses, align the optical path, and learn how every component works!
