Žvaigždžių diagrama, Planisfera, Omegon

The Omegon planisphere is the best way to learn how to recognise stars and constellations. It's your guide to the stars!

A planisphere consists of a round celestial chart, with one celestial pole in the centre. That star chart shows all stars, constellations and objects like nebulae (see below), that are visible in a certain area. The starry sky is not always the same, however: stars rise and set and in the summer you see a different sky than in the autumn, winter or spring.

That is why the planisphere has another disc, on top of the star chart. This disc has a transparent opening, the horizon opening, that shows what part of the starry sky is visible at a certain date and time. And the planisphere can be very easily set for that date and time.

The Omegon planispheres in short:

• show the starry sky for every moment of the year
• are very accurate, pretty, well thought-out and cheap
• are very easily set for the desired date and time
• contain over 700 stars and about 300 ‘objects for binoculars”: deep-sky objects like galaxies, nebulae, clusters, double stars and so forth, that are visible to the naked eye or at least with a normal pair of binoculars
• are suitable for age 10 and older
• last a life time... or longer!
