Cretney Observatory News
Above: One of the latest Cretney images, IC434, taken by Curator of Instruments Matt Balkham. 12.5 hours of HaRGB. If you’d like to see the version with stars, here’s the link.
Keen to use the Cretney? We now have instructional videos on our YouTube channel. Below is a link to Matt’s video explaining how to select targets to image using the Cretney. He writes:
‘In this 2-part video I share key info on how I have been finding candidate targets to image with the Wellington Astronomical Society Cretney Observatory. (Part 1 here https://youtu.be/xWUeVwW9JqQ?si=HGaqypx3XG9R1MIs)
‘We hoping that members will use this info to identify object that they want us to target. Check that our equipment is suitable and understand the best time of the night and the year to capture data of that target.
‘Key info if you are keen is 1520mm focal length and QHY600 full frame camera with a field of view of 1.3×0.9 degrees. https://astronomy.tools/calculators/field_of_view/
‘Framing and transit timing here https://telescopius.com/
Coming up this year:
- A workshop on astrophotography, and the formation of an active astro group within WAS
- A workshop or two on how to use the Cretney, with manual
- A workshop on how to process Cretney data to produce beautiful images like the one above, and
- Whatever else you tell us that you need to get the benefit of your WAS membership and access to the Cretney Observatory. Talk to Matt Balkham, Anne French, or any Council member about your ideas.

Get involved with WAS
Is there anything more awe inspiring than looking through a telescope to see the wonders of Matariki, or showing a child the rings of Saturn?
It’s been a bit hard over the last few years, especially if you don’t have access to a telescope of your own.
Running outreach events, holding viewing sessions, teaching telescope skills, running observatories (and mowing their lawns), arranging astrophotography nights, writing funding applications, managing social media accounts, finding guest speakers, making the tech work at our meetings… it all takes time! So this year your Council has decided we want to have more fun and spend more time with our members.
Very shortly we will send out a survey form to members, asking how you would like to be involved in your society and what you are most interested in doing.
After we have your response, a Council member will be in touch. There are three things we can guarantee:
• We won’t ask for more time than you can give
• You don’t have to know about astronomy to get involved
• It will be loads of fun!
Gifford Observatory Refurbishment and News
A few days ago, we had a break-in at the Gifford Observatory. Some schoolboys stole various cameras (by ripping the cables out), damaged the guttering and the fence, knocked a hole in the door, and tried to burn the place down. Fortunately their actions were caught on our CCTV cameras, and they have been referred, via Wellington College, to the Police. A substantial insurance claim is in progress. This is a set-back, but the working bee at the Gifford will be going ahead on Sunday 7 April. Contact Andrew Fuller if you’d like to lend a hand
The Gifford Observatory was originally established in 1911 on the slopes of Mt Victoria, where Wellington East Girls’ College is located now. It was moved to its present location, above Wellington College, in 1924. It was named in honour of its original founder and benefactor, A.C. Gifford, also known as Uncle Charlie.
The Observatory hosted a Zeiss 130 mm refractor and was operated by Wellington College students until the late 1970s, by which time adult support for its continued operation had faded out. The dome eventually rotted and collapsed, leaving only the shell of the building.
In 1999, the Gifford Observatory Trust was formed. Its aim was to ‘restore, maintain and operate the original Gifford Observatory to establish a usable astronomical observatory for the recreational use of young astronomers in the Wellington region’.
The Trust refurbished the building with a new 4.5-metre dome and reinstalled the 130 mm refractor. The Gifford was reopened on 25 March 2002 by one of its former student users (and New Zealand’s most distinguished rocket scientist), Dr William Pickering ONZ, KBE. (see below).
In 2022, the Trust was dissolved, but not before it had transferred the ownership (and upkeep) of the Observatory to the Wellington Astronomical Society. We are now renovating the observatory with the aim of making it fully automated.
Interested in helping Andrew with the refurbishment of the Gifford? Have a chat with him at the monthly meeting or contact him at adfuller@gmail.com.
William Hayward (Bill) Pickering (1910–2004) was a frequent user of the Gifford Observatory during his school days at Wellington College. He finished his BSc at Caltech and completed his PhD in Physics there in 1936. A few years later, in 1944, he went to work at the Jet Propulsion Laboratory. On 31 January 1958, his group at JPL launched Explorer I on a Jupiter-C rocket from Cape Canaveral, less than four months after the Soviet Union had launched Sputnik. It’s a tale of innovation on the surface, but it’s worth remembering that rockets for space could not have been developed so fast without the rocketry programme of the Second World War – as the Jupiter-C’s history shows. It was designed, eerily, by Wernher von Braun, who worked on the V-2 rocket for Nazi Germany’s weapons programme during the war. Von Braun was spirited off to the US afterwards, as part of the innocuous-sounding Operation Paperclip. Similarly, the R-7 rocket that launched Sputnik 1 was originally developed as an Intercontinental Ballistic Missile, i.e. an offensive weapon capable of travelling thousands of miles.
