The sun in full glory, safe and sharp
The Omegon AC 70/400 Solar BackPack AZ is a smart, portable refractor telescope designed specifically for safely observing the sun and solar eclipses. With its 70 mm opening and 400 mm focal length (f/5.7) it offers a clear, high-contrast view of sunspots and fringe phenomena during an eclipse.
The CE-certified sunscreen blocks 99.999% of sunlight, completely safe for the eyes. So you enjoy impressive sun images without any risk, whether you are watching at home, traveling or in the middle of nature.

Compact and ready to go
Everything about this telescope was made with mobility in mind. The lightweight azimuthal mount is easy to operate, and the entire set, telescope, tripod, eyepieces and filter, fits into the included backpack. Within minutes it is set up and ready to use. Perfect for travelers, eclipse hunters and nature lovers who don't want to lug around heavy equipment.

Safe observing with certified solar filter
The safety filter with CE marking guarantees safe observation of the sun. The filter lets only a fraction of the light through and eliminates harmful UV and infrared radiation. This allows you to see sunspots, fringe phenomena and shadows during a solar eclipse with razor-sharp clarity.
⚠ Important: Never look at the sun without sunscreen. Adult supervision is mandatory when used by children.

Versatile use
Although the Solar BackPack is designed for the sun, it offers much more. Remove the solar filter and you have a full-fledged 70 mm lens telescope for:
- The moon - with craters, mountains and terminator shadows
