Welcome SPIRIT 4

SPIRIT 4, our newest donation thanks to Mr Colin Eldridge, has been installed adjacent to SPIRIT 3 at the Zadko Observatory.

This unique telescope offers a 50 arc minute field of view
(the SPIRIT initiative’s largest) and is perfect for wide-field imaging of nebulae and clusters (see example ‘first light’ images below). It is equipped with astrophotographic filters including a 5nm bandpass hydrogen alpha filter.

As with SPIRIT 3, the newest member will operate most of the time in scheduled mode. Details of SPIRIT telescope ‘modes of operation’ are outlined in the guides and documents section of this web site.

More information on accessing SPIRIT 4 will be made available in the coming weeks.

Our gratitude and thanks to Colin for this exceptional donation.

Introducing SPIRIT 3

A generous donation of a telescope, mount, imaging and ancillary equipment from Mr Neil Shaw and his wife Tara has expanded the ICRAR’s SPIRIT outreach initiative with a 3rd robotic telescope.

Located in UWA’s Zadko Observatory 1 hour north of Perth and with much darker skies, the first light results show an impressive improvement in image quality further increasing the potential for student research:

As with all SPIRIT telescopes, students book and then remotely access and control the instruments in ‘real time’ from their home or school computers using nothing more than a web browser.

Telescope operations are monitored by students as they happen and images appear on their screens as they are acquired. Using a customised version of ACP’s innovative web interface also provides for automated and unattended data acquisition. Advanced students and researchers can collect data ‘while they sleep’ by uploading observing plans in advance.

ICRAR & UWA acknowledged this wonderful donation from the Shaws during a small event on April 18th.

Student piloting and use of SPIRIT 3 is currently underway. More information on wider access to SPIRIT 3 will be made available in the coming months.


Donation of the ACP Observatory Control software was generously provided by DC-3 Dreams (Bob and Stephanie Denny)

Discounted hardware upgrades were generously provided by Software Bisque (Steve Bisque)

Support through the donation of additional software and hardware is also acknowledged:

Happy Birthday SPIRIT II

SPIRIT II was officially launched on September 6, 2012.

SPIRIT I and SPIRIT II continue to provide teachers and students access to research grade astronomical imaging and data collection via the internet, supported by a full life-cycle of SPICE teacher learning opportunities and student activities. In 2013 alone, 212 participants from 26 different institutions attended some 15 SPIRIT professional learning workshops at the Centre for Learning Technology.

Students from Western Australia and beyond continue to utilise SPIRIT to take stunning images of distant astronomical objects, as well as undertake ‘real science’ with these unique instruments.

Happy 2nd Birthday SPIRIT II


Cleaning the SPIRIT optics

Cleaning the optics of  SPIRIT telescopes requires a great deal of care. The surfaces of primary mirrors in particular are extremely delicate, and can be damaged using conventional cleaning techniques. Telescope optics should never be touched, though traditional surface cleaning techniques usually include surface contact. Washing mirrors introduces other problems such as streaking and can be difficult to undertake with telescope optics in situ. Moisture ingress at the edge of primary mirrors can also affect coatings over time.

The annual SPIRIT mirror cleaning routine includes the application of a polymer solution called First Contact that absorbs surface dust and debris. It dries as a flexible film that has minimal surface adhesion so that it can be safely removed without affecting delicate surface coatings.
