Professional observatories use iTelescope.Net to supplement current research projects. The network provides alternate observatory sites in both southern and northern hemispheres and is a good way to continue research when seasonal poor weather hits your observatory.

Sky Tours Live Streams

We offer a variety of ways to view the night sky, including our entry level Sky Tours Live Streams. These weekly streams, hosted by Dr. Christian Sasse, are a great way to get started with Remote Astronomy, allowing you to see our telescopes in action and learn about the Night Sky from a professional Astronomer.


Take stunning images of the night sky, galaxies, comets and nebula. Have access to the best equipment from the comfort of your computer and without the huge financial and time commitments. (more)

The network has everything from beginner telescopes with single shot colour CCDs to large format CCDs with Ha, SII and OII and LRGB filter sets. Check out the member image gallery – the results speak for themselves.

Depending on your own image processing skills, you can even land yourself a NASA APOD.


All you need is a web browser and an Internet connection; iTelescope.Net takes care of the rest. Our web-based launchpad application provides the real-time status of each telescope on the network as well as a host of other information such as a day-night map, observatory all-sky cameras and weather details. (more)

From the launchpad you can login to any available telescope, and once connected, you’re in command. Watch in real time as the telescope slews, focuses and images your target.

The image files (in FITS format) are then transmitted to a high-speed server ready for your download. All image data taken is your data – iTelescope.Net doesn’t hold any intellectual property rights.

Reserve and schedule observing plans in advance, even have them run while you are away from iTelescope.Net and have the image data waiting for you ready for download.

New and Starting Out?

A number of telescopes are fitted with colour cameras; these systems have been designed for ease of use. It’s as simple as selecting an astronomical target from the menu, watching the telescope image your target, and have the resulting image sent to your email address as a jpeg attachment. (more)

The image file is also sent to our high-speed server and can be downloaded in its raw image format, for post image processing if you want more of a challenge.

Our dedicated support website allows members to seek answers to frequently asked questions. Formal support can be requested by lodging a support ticket, which can be viewed, tracked and managed through to completion. Go to or simply email

Our contact details are also available. You can phone or Skype us if you want to speak to a person directly; you can also contact us via Skype instant message, email and fax.

How much does this cost?

Rates vary based on your membership plan and the phase of the moon. Rates start as low as 17 to 100+ points per imaging hour, which is billed per minute of imaging time used; typically one point equals $1. Make sure you are subscribed to our newsletter for special offers. Please visit our pricing page for more information on telescope operating rates. (more)

Each telescope has its imaging hourly rate displayed in real time in the launchpad before you login. At the end of each session you are also sent a detailed usage receipt which includes the costs, weather data, preview jpeg images and your observing session log file.

Membership Plans

We have a range of plans catering for everyone from the amateur to the professional astronomer. Each plan provides unrestricted access to each telescope and includes the plan’s dollar value in points, which is credited to your account each time the membership renews. (more)

Membership plans set the usage rates for each telescope on the network, expressed in points per operating hour. The entry level plans provide maximum flexibility on our single shot colour systems, and the heavy usage plans focus more on the large research grade systems. Memberships start from $19.95 and range to $999.95 per 28 day period.

Additional points can be purchased at any time to supplement your account balance.

iTelescope.Net: Outreach in Action!

A couple months ago, we received word from one of our Educational Group Accounts of a project completed by two year 11 students during their own spare time using iTelescope systems.  We are very excited to share some of this wonderful research with you today!

Vina Hing
 and Linh Thuy Nguyen are two students in year 11 at Prairiewood High School in New South Wales who took on a fantastic research project studying the binary system SZ Scl.  They used T9 on the iTelescope.Net Outreach Grant Program to collect photometric observations in B and V during their spare time, of which there is very little for students in year 11.

They then reduced all of their observations using the Vphot system and uploaded all their data to the AAVSO's database.  Using their data, as well as other recent data from the database, they then used Binary Maker 3 software to analyse the system.  Their mentor and supervisor, Giorgio Di Scala, then created his own analysis and the group compared the work to one another, and they found that the analysis was nearly identical, which is an amazing feat for these busy students!

The project was so fantastic, that on 30th of April, Vina and Linh received First prize at SciCon15, a gathering of five schools from the Met South West area created to link the aspiration and scientific genius of students with the opportunities that await them in the world of science.  The Macquarie University Faculty of Science and Engineering awarded a prize valued at $1,000 shared across the 4 prize winners, including Vina and Linh.  They were also granted passes to Questacon Science Centre in Canberra!

We are very happy to have been even a small part of this project, as one of the primary goals of iTelescope has always been to bring individuals access to telescope systems and dark sky sites they would normally be unable to use, and this project was a great example of that ideal being put to fantastic use!

iTelescope Siding Spring - Meeting the Demands for Public Astronomy & Science

Our flagship iTelescope facility was approved & construction commenced within the grounds of the Australian National University's Siding Spring Observatory (SSO) during 2012 and was completed in early 2013. Designed and constructed by local engineers from the town of Coonabarabran, it has exceeded all our expectations and performs brilliantly as the world's largest purpose built roll off roof (ROR) observatory. We are all justly proud of our Australian based service.

But here we are only 18 months down the road from its first night open to the southern skies and we find ourselves at maximum capacity. We are full of glorious remote telescopes!

iTelescope.Net provides public access to research grade instruments and our range of sophisticated public telescopes is constantly expanding due to the demands of our ever growing membership, but we also offer our southern, dark sky location to advanced amateurs and international institutions, enabling them to house their own telescope as a hosted imaging system within our facility and this has proved to be a very popular option to those lucky few that got in early. We now have a waiting list for space within our current observatory.

Due to the increasing public demand for more of its 'on demand' telescope systems, iTelescope.Net is initiating an observatory expansion project at SSO and are planning to add more telescopes adjacent to its current structure in the next 12-18 months.  This expanded facility will take the form of either a new ROR observatory similar to the existing building or a tight cluster of up to 6 clamshell domes housing multiple systems and erected as public demand dictates.

We have already found a location for the expansion adjacent to our current observatory and this will greatly simplify construction with our own existing power and communication services only a few meters away.

We will be adding more amazing telescopes for our members to use with this expansion project and we also invite any institutions with a passion for science education to contact us to include and operate your own remote telescope under the pristine and dark night sky of Siding Spring Observatory in Australia.


Back to the Beginning of Time

The four most distant galaxies ever imaged with an amateur telescope

Amateur astronomers and iTelescope members Josep Drudis and Christian Sasse have just imaged the four most distant objects ever seen with an amateur sized, off the shelf telescope. These four galaxies emitted light when the universe was only 760 million years old, or 6% of its present age - it was very very long ago, in fact they are looking back over 13 billion years!

Why did they do it? It was a cool idea - previous records were obtained on distant quasars - very bright compact galaxies. Redshift is a measure of distance since the further away an object is, the more it is redshifted.

This also means that the light emitted from a very distant galaxy is no longer visible to most cameras, its light has simply passed too far into the 'dark' red portion of the spectrum and is thus difficult to detect.

Drudis and Sasse wanted to go beyond a redshift of 7, and it was difficult to find suitable objects. They searched for and found four very distant galaxies and used T17 with its special camera and 400mm (17 inch) CDK optics located under ideal clear and cool skies at iTelescope's remote observatory at Siding Spring Observatory in Australia for this purpose. This CCD telescope combination could 'see' more into the red bandwidth of light. 

T17 is a powerful amateur science platform. It is normally used for Science Missions, Deep Photometry, Narrowband and 'Extended Red' light IR imaging missions.
Clearly it was a challenging task for all involved, including dedicated ground staff. It takes many hours of careful aligning, testing and imaging required until the objects finally appeared. This result was somewhat unexpected and a pleasant surprise for all involved.
Below are images of the four galaxies. Drudis and Sasse are keen to continue and push the envelope of amateur imaging even further.
