Armagh Observatory and Planetarium
College Hill, Armagh, BT61 9DB
Visit Armagh Observatory and observe the transit of Mercury… See the Observatory Boardroom, the historic clocks and a rare opportunity to see the telescope used by King George III to observe the 1769 transit of Venus. Then head out to the Human Orrery and use our telescopes to view the face of the Sun. Also grab the chance to use our 19th Century, Grubb telescope, that was used to compile the famous New General Catalogue of Nebulae and Clusters of Stars in 1888, to see the transit in action. The transit starts at 12.30pm and will be at its greatest at at 3pm and continues until sunset. The Observatory doors will be open from 2pm – 5pm.
