  • welcome to

    macarthur astronomical society

  • observe

    Astronomers use scientific observation to learn about the Universe we live in. It's a beautiful place and, as a group of keen amateur astronomers, M.A.S. members have it as their common interest. We observe from two southern Sydney locations.

  • photograph

    Along with our "visual" observers, we have a group of dedicated astrophotographers within our ranks. This group find that photographing deep sky objects with high-quality cameras brings out the colour which your own eyes are unable to detect. See our photographs and you'll want to take your own.

  • educate

    Come to a Macarthur Astronomy Forum evening, held at UWS Campbelltown, to hear talks given by Australian and international professional astronomers as well as from amateurs with interests in their own specific fields. Entry is free for all.

  • events

    M.A.S. members are deeply committed to sharing our combined knowledge of, and love for, the night sky and the science of astronomy. We hold public open nights during the year - keep watching out for "What's On".

Loan Telescope Images

 

Availability & Conditions

The Society owns three telescopes which, subject to availability, may be loaned under the MAS Education Programme to current MAS members. There is a three month qualifying period for new members.

Due to the size, weight and complexity of telescopes, children using MAS Loan Telescopes must be supervised by an adult at all times.

Loanees need to ensure that the telescope will fit into their motor vehicle safely and securely and must take special care to protect it from damage during transportation and keep it safe during storage.

Subject to demand, the loan period is normally a maximum of two months, then on a week by week basis. As the telescopes are used to support external MAS Education programs they may not be available all year.

Users not familiar with the operation of the telescope they are borrowing will be given full instruction on its use. This is best achieved at an MAS members viewing night e.g. Stargard, which also offers a good way to meet other members and learn the night sky from experienced observers.

Loan Agreement

Borrowers will be required to sign the agreement before taking the telescope; and accept responsibility for returning it in good condition promptly at the end of the loan period. Please view the generic form > Here <

Due to each telescope having a different inventory, there are specific Telescope Loan Agreement forms for each telescope. However, the terms and conditions for each Telescope Loan Agreement are the same. 

To borrow an MAS Loan Telescope please contact the Telescope Curator.

Cost

Loaning our telescopes is a free service to our members, which we hope may broaden your understanding of the Universe. Should you feel inclined to make a small donation to our maintenance costs for using this service, we would welcome that.

Camden Library Loan Telescopes

MAS has collaborated with Camden Library, who also have astronomical telescopes available for loan.

MAS provide telescope servicing assistance to the Library and assist with operational advice.

Anyone who is a member of Camden Library can borrow one of their telescopes. Due to demand there may be a waiting period.
