Special ruler with Radiant circles to make it even easier to find objects in the star atlas and in the sky.
Having a radiant is one thing, finding an object in the sky is another. But with this newly designed radiant ruler, locating objects is easy. Radiant circles in 7 different scales fit most common star atlases. Simply place the transparent ruler over the map and you will be able to find the exact path to the celestial object.
The ruler fits these star atlases:
- Deep Sky Travel Atlas
- Pocket Sky Atlas
- Kosmos Star Atlas Compact
- Pocket Sky Atlas Jumbo
- Sky atlas 2000
- Uranometria
- atlas for Sky Observers
A nice extra: with a printed table, you can immediately find out which magnification and eyepiece focal length is best suited for nebulae, galaxies, double stars and other objects directly under the starry sky.
