iTelescope.Net is the world’s premier network of Internet connected telescopes, allowing members to take astronomical images of the night sky for the purposes of education, scientific research and astrophotography. (more)

iTelescope.Net is a self-funding, not for profit membership organisation; we exist to benefit our members and the astronomy community. Financial proceeds fund the expansion and growth of the network. iTelescope.Net is run by astronomers for astronomers.

The network is open to the public; anyone can join and become a member including students, amateurs and even professional astronomers.

With 20 telescopes, and observatories located in New Mexico, Australia and Spain, observers are able to follow the night sky around the globe 24x7.

iTelescope.Net puts professional telescopes within the reach of all, with systems ranging from single shot colour telescopes to 700mm (27”) research grade telescopes.

Astronomy Research

Having access to professional telescopes means that doing real science has never been easier – great value for schools, educators, universities, amateur and professional astronomers. (more)

Exo-planets, comets, supernova, quasars, asteroids, binary stars, minor planets, near earth objects and variable stars can all be studied. iTelescope.Net can also send your data directly to AAVSO VPhot server for real-time online photometric analysis.

iTelescope.Net allows you to respond quickly to real-time astronomical phenomena such as supernova and outbursts events, gaining a competitive edge for discoveries. With more than 240 asteroid discoveries iTelescope.Net is ranked within the top 50 observatories in the world by the Minor Planet Center.

Get involved: members have used the network to provide supportive data for go/no-go decisions on Hubble space telescope missions.

Education and Astronomy Schools

With science and numeracy at the forefront of the education revolution, iTelescope.Net provides the tools, along with research and education grants, to support the development of astronomy or science based curriculums in schools. Contact iTelescope.Net about a grant for your school or research project. (more)

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.

Already a Pro?

iTelescope.Net offers a large range of telescopes, fields of view and image scales, and NABG and ABG CCD camera combinations. Select from a large range of filters including narrowband, LRGB and UBVRI, as well as control pointing, filter selection, focusing, exposure times, image counts, repeat loops etc. All data is offered in its raw FITS format calibrated and non-calibrated.

Support and Service

With remote astronomy observing plans can be interrupted from time to time, by clouds, wind gusts and even a rare equipment failure.

iTelescope.Net has you fully covered with our satisfaction guarantee; we will return your points if you are unsatisfied with your results. Help is just a click away. (more)

A dedicated team of professionals are working around the clock to keep the network operating. This includes local ground crews at each observatory, sophisticated monitoring systems and remote observatory administrators monitoring the quality of data coming off the network.

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.

Dr Ian Musgrave  - iTelescope Science Advisor

An avid amateur astronomer, Ian writes the weekly sky updates for ABC Radio Science and is science adviser to iTelescope. When not staring at the sky he is an equally enthusiastic molecular pharmacologist at the University of Adelaide, Australia.

You can follow Ian Musgrave on his Astroblog for daily posts about astronomy, biology and life, the Universe and everything.

"Over at Astroblog I largely guide people to the view of the sky as seen with the unaided eye. But I’m also an iTelescope.Net user, and I’m very honoured to have been invited to highlight some of the interesting objects that can be seen through the iTelescopes.

While many people are familiar with the larger, more glamorous objects in the night sky that make good iTelescope targets, there are a host of lesser known, interesting objects that are well worth chasing such as fast moving Near Earth Objects, Novae and Comets."  Twitter @ianmusgrave


ALERT! Comet C/2015 WZ PanSTARRS Brighter than Expected

Comet C/2015 WZ PanSTARRS as seen from Mayhill New Mexico 30 minuttes before Astronomical Twilight n the morning. The large rectangle is the field of view of T14/T20, the small that of T05.

Comet C/2015 WZ has been reported to be anomalously bright. It's predicted magnitude is 17.7, but recent observations have consistently reported the magnitude brighter at between 13.5-11.5 (there is a big thread on comets-ml about its magnitude and comet magnitude measurement generally).

Suggestions range from an outburst to a meteor impact. Observations are required to follow this anomalous brightening. The comet is just north of beta Pegasii at the moment, moving towards Lacerta.

It is high enoughabove the horizon in the moring to image from 30 minutes before astronomincal twilight to astronomical twilight.

ALERT! Comet C/2014 S2 PanSTARRS close to M108 (16-20 April)

Chart showing comet C/2014 S2 PanSTARRS close to M108 and the Owl Nebula on 18 April 22:00 (19 April UTC) as seen from Mayhill New Mexico. The large rectangle is the filed of view of T14/20, the small that of T5. Click to embiggen.

While at lot of attention has been focused on the unexpectedly bright comet 252P, and the spectacle of comet 67P going through the Leo Triplet, comet C/2014 S2 PanSTARRS has also been brighter than expected.

Only visible to the northern scopes at the moment, it is passing through Ursa Major and is currently magnitude 10 rather than magnitude 16.

From April the 16th to the 20th (local time Mayhill 17th to 21st UT) the comet will be within T14/T20 range of the magnitude 10 galaxy M108 and the magnitude 10 Owl Nebula. On the 18th it passes between M108 and the Owl Nebula (see chart above).

The low surface brightness of these objects means that longer exposures are needed. However, since the comet is withing scope travel from astronomical twilight to around 3 am there is plenty of time. On the other hand the waxing Moon will interfere until around mid morning.

ALERT! Comet 252P Crosses the Scopion's Tail

The path of Comet 252P as it crosses the tail of Scopio and into Ophiuchus from March 25 to March 30. The large rectangle is the field of view of T12. Click to embiggen.

Comet 252P has passed its closest approach to Earth and from the 25th to 30th March will be in a cluster and nebula rich region in Scorpion's tail and the Ophiuchus. There are so many potential objects that it would take ages to list them, but notably on the 27th the comet is within 2 degrees of the Butterfly cluster (M6) and many smaller ones are closer.

The comet is best visible after 1 am from SSO, and won't really be visible from the northern hemisphere scopes until the 26-27th, at astronomical twilight in the morning.

Unfortunately, the waning Moon is close for most of this time, less than 40 degrees from the 27th, and within T12/14/20 field  of view on the 30th. Narrowband imaging will probably be okay up to 29-31 March, the even though waning the Moon will be sufficiently close to significantly interfere.

Also the comet is still moving fast and you will need to take short images so the stars do not trail too much and ruin the cluster glory. Fortunately the comet is still bright, so short exposures will bring it out.

ALERT! Nova Oph 2016 in Ophiuchus

Location of Nova Oph 2016, below the tail of the Scorpion, as seen from SSO at 00:30 AEDST.

A new (bright?) nova has been seen in the constellation of Ophiuchus. Onservations in the I band have it around magnitude 8, while in B it is around 14 and 12 in V. B and V magnitudes have faded a bit since discovery.Details of the evolution of the nova, and its discovery are here.

The nova is below the tail of Scorpius, while the field isn't TOO crowded, there will be a lot of stars to get confused with.The nova can been seen from both SSO and northern hemisphere scopes.

The location is R.A. 17 35 50.41  Dec. -29 34 23.8 (J 2000 coordinates)

Telescope field for Nova Oph 2016, using the SSO scope CCD's as exemplars. The large rectangle is the field of view ofT12, the small that of T9. Click to embiggen.

The nova should be high enough to image from 1:00 am until astronomical twilight.
