A star party will be held at Green Point Observatory on May 23 as part of an attempt to set a new world record for the most people stargazing at multiple venues at one time.
The observatory at Oyster Bay joined in setting the present Guinness World Record on August, 21, 2015, which was 7960 people across 37 sites.
Australian National University (ANU) is partnering with the ABC Stargazing Live program, with Professor Brian Cox, in the new bid, centred on Mount Stromlo Observatory on Wednesday, May 23.
Sutherland Astronomical Society’s star party at Green Point Observatory runs from 7pm to 10pm.
The society is hoping for an even bigger number of stargazers than the 227 who took part three years ago.
By Monday, May 14, a total of 165 registrations had been received and the number was expected to easily double.
Entry is free but bookings are necessary and, for world record setting purposes, each person must have a telescope or binoculars.
A telescope can be bought for $7.15 when registering.
The observatory will have a big screen showing the ABC broadcast.
A sausage sizzle will be run by 1st Oyster Bay Scouts.
The firm Sky-Watcher will give away a Dobsonian telescope as a lucky door prize.
Bookings via SASI.net.au with May 22 the closing date.
