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.

Hosting and Affiliates

iTelescope.Net offers a range of telescope hosting solutions to members with special projects, allowing you to host your own telescope at three of our four observatory locations. Conditions and approvals apply. Contact us for more information.(more)

Affiliate membership allows you to connect your own telescope to iTelescope.Net with reasonable rates of return. Limited availability exists and is subject to telescope network balance.

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! Nova PNV J18205200-2822100 passes Magnitude 6.0

Chart of the location of PNV J18205200-2822100 (labelled Nova Sag 2016) as seen from the SSO scopes, the rectangle is the field of view of T12. The star next to Nov Sag 2016 is magnitude 6. Also shown is TCP J18102829-2729590 (labelled Nov Sag 2 2016) Currently magnitude 9 . Click to embiggen and print.

I have been out of commission with colds/flu's, so two nova exploded in Sagittarius, both near the teapot of Sagittarius. One, PNV J18205200-2822100,has been slowly increasing in brightness and has now broken the unaided eye brightness threshold of magnitude 6.0, with the latest report from New Zealand of 5.4.

PNV J18205200-2822100 is in the "teapot" of Sagittarius between Kaus Borealis (lambda Sagittarii and Kaus Media (delta Sagittarii), Howevere, it is just at the limit of scope trave just before astronomical twilight, giving a very narrow window of imaging.

ALERT! Bright (Magnitude 6.9) Likely Galactic Nova

Location of the bright likely galactic nova in Lupus between the pointers and Antares as seen from SSO at Siding Spring in Australia looking west at 9:30 pm local time.  Visible only from the SSO scopes for around an hour after astronomical twilight, the latest astronomical telegram on 26/09/16 08:30 UT has the probable nova between 6.9 B and 6.3V. (Click to embiggen).

The Astronomical telegrams reported a bright probable nova ASASSN-16kt not far from epsilon Lupi at
RA 15:29:01.82, DEC -44:49:40.89 (J2000.0) at magnitude 9.1. The nova has rapdily brightened and is now almost unaided eye magnitude according to the latest astronomical telegram with its reported magnitude between between 6.9 B and 6.3V.

UPDATE: Nope definitely around magnitude 6 when I did proper estimates. On the other hand a quick and dirty visual estimate I just did suggested the nova was below mag 7, but then it was pretty low to the horizon at the time amongst the murk, but other dim stars were showing up.

Magnitude chart for nova Lupi magnitude estimates showing magnitudes from 5 to 7 (in a stupid format [988] means mag 9.88, [1098] means 10.08 etc.). The large rectangle is the field of view of T12, the small that of T9. Click to embiggen


ALERT! Bright (Magnitude 11) Galactic Nova

Location of the galactic Nova between Scorpius and Ophiuchus, between the Butterfly cluster and M62. The large rectangle is the field of view of iTelescope T12 the small that of T9. Click to embiggen.

An apparent nova of magnitude 11.4 has been detected in the direction of the galactic centre has been detected by the All Sky Automated Survey for SuperNovae. Follow up observations are urgently required. J2000 coordinates are:

RA 17:22:51.426 DEC -31:58:36.28

Magnitude chart for nova magnitude estimates showing magnitudes from 8 to 12 (in a stupid format [988] means mag 9.88, [1098] means 10.08 etc.). The rectangle is the field of view of T9 (sorry, sky map doesn't go lower than mag 12)


ALERT! Comet 174P in Outburst

Location of comet/asteroid 174P/Echeclus as seen from Mayhill Newmexico around 3:00 am local time. The large rectangle is the FOV of T14/20, the small that of T05. Click to embiggen.

174P/Echeclus has been reported to be in a rare outburst. Originally described as a Centaur object, it has since shown cometary features, with outbursts in 2006 (when it shed a fragment) and 2011.

The comet has jumped from magnitude 17.9 to 15.2. Faint to be sure, but reachable with several of the iTelescopes.

Observations are required to follow the progress of this outburst.

The comet is in Pisces, near Uranus. The comet is visible in iTelescopes in both the northern and southern hemispheres (although north is best) from around 11 pm local time, transiting around 3 am and still accessible until astronomical twilight.
