A unique astrolabe, a handheld astronomical computer from the Jaipur Royal Collection in India, is set to be auctioned.

It will be sold at Sotheby's in London on the 29th.

The brass instrument is believed to be the largest known astrolabe in the world and has never been exhibited before, said Benedict Carter, head of Islamic and Indian art at Sotheby's.
