"We were going to an observatory, but instead decided to watch with our binoculars," he said. "It was a fizzer because we could hardly see it all."
Hooked on the night sky, in 1987 Mr Redward went to an auction of telescopes at Dunbar Sloane in Wellington.
"All the talk was of the Celestar 8 telescope, but I didn't think my pockets were deep enough for that, so I bid for and got, a long telescope for $500," he said. "But then the Celestar 8 came up and the auctioneer asked 'how much?' I quietly said $1000, but bid $500. There were a couple of $200 bids and then it was mine."
At the auction, Mr Redward met Frank Andrews, curator of the Carter Observatory in Wellington.
"He advised me to purchase the accessories for the telescope at the auction," he said.
"When I arrived back home, my kids were excited as they discovered all the boxes in the car, but I wasn't in my wife's good books. I'd spent the $2200 which was going to pay for a trip to the United Kingdom."
Mr Redward said the highlight of the year for the society is Stellarfest, or the Astrophotography weekend on August 14-16 at the Foxton Beach Bible Camp.
"This is a wonderful event and I went last year," he said.
"It's a chance for observing, talks and chit-chat in front of a warm fire and we have some stellar speakers, including Professor Paul Delaney of York University, Toronto, and Dr Peter Eisenhardt, from the Jet Propulsion Laboratory. The general public can attend too."
