The Hubble SkyHub-B is a Bluetooth/USB based controller which constantly monitors the position of the telescope via two encoders attached to two telescope axes. This position information is sent to an Android, Windows, iOS or Mac OS based device, and the scope’s pointing direction is then updated on the screen in real time via your favorite planetarium software.

Just point your scope to any star, and touch the same star on the Sky Safari, which will complete the one star alignment. Then you simply touch any star on the screen, and move you scope until your Scope’s position mark exactly meets the target star on the screen …“Ding”, done!

Optionally, you can perform a two star alignment at any time for better pointing accuracy.

Hubble SkyHub-B Digital Setting Circle comes with revolutionary high resolution (8192 PPR), extremely compact, and highly energy efficient ball bearing encoders. It is 80% more power efficient, and is only about 15% size of a traditional encoder.
