Green Witch is the trading name of Greenwich Observatory Limited and is one of the UK's leading suppliers of telescopes, binoculars and related equipment and services

The company was set up by former staff of the Royal Greenwich Observatory following its closure in 1998. In fact, the RGO closed on 31st October and Green Witch started trading on 1st November. We therefore claim that Green Witch was born at midnight on Hallowe'en.

We have a strong background in professional research astronomy but are also keen amateurs. We offer friendly advice and our aim is to help you choose and use the equipment that is right for you.

You can seek our advice by phone or email, or by calling at our well-stocked showroom; please ring for an appointment.

We have plenty of free parking and are easily accessible from the M11, A1 and A428.
