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.

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


UPDATE! New Orbital Elements for P/2010 V1

New orbital elements have been published for P/2010 V1 (Ikeya-Murakami). The elusive comet was recovered as object P10qxlX (MPEC 2016-A10), some 8 magnitudes dimmer and well over 5 degrees away from previous predictions, in Lynx rather than the sickle of Leo.

Hidetaka Sato, who recovered the comet, suggests an object MaWi031 in PCCP is a fragment from this comet.

Obsevations are still requested, but it will be a challenging faint object.

ALERT! Bright Supernova in NGC 7213, Observations requested

Chart of the western sky as seen from SSO at astronomical twilight in the evening 21:29 local daylight saving time. The location of NGC 7213 and the supernova is indicated with the black box.

A bright supernova (magnitude 14.7 as of last observation, and likely to get brighter) has been detected in the galaxy NGC 7213 ( see ATEL # 8474 and further follow-up here). Observations are requested for follow-up from southern scopes.

NGC 7213 is close to Alpha Grus, and fairly easy to find (although the bright star may cause some imaging artefacts). Unfortunately, it is also 30 degrees from the western horizon at SSO at astronomical twilight, so the imaging window is short.

The location of the supernova is
R.A. = 14h10m23s.42, Decl. = -43°18'43".7

ALERT! Observations Required for Recovery of Comet P/2010 V1 

The location of comet P/2010 V1 (Ikeya-Murakami) as seen from Mayhill New Mexico at 10 pm local time. Click to embiggen.

Observations of comet P/2010 V1 (Ikeya-Murakami) are required for its recovery. While the comet is in a good location, between Leo and Leo Minor, and theoretically should be between magnitude 10-11, as of December 9 nothing was observed down to magnitude 20. While the ephemeris magnitudes are bright, it may be dimmer than the last visit, or may have even disintegrated in the big outburst at its last visit.

The comet is best observed in the Northern Hemisphere scopes, where the comet is at a suitable height for 10pm to astronomical twilight, being highest at 3 am local time.

In the SSO scopes, the comet is only high enough for the local scopes from 3 am local time until astronomical twilight at 4:20 am.

The bad news is that for the next few days bright waning Moon will interfere with gaining images of a potentially dim comet.

ALERT! Fast NEO 2015 YB on 18-19 December, 2015

UPDATE: The designation of asteroid 2015 YB has been withdrawn, it is a non-object.

Newly discovered NEO 2015 YB as seen from SSO from Astronomical twilight (20:00 pm, 9:00 UT) 18 December - 19 December. The crosses mark the position of the asteroid every 1 Hour, the black square the JPL Ephemeris position at 11:00 UT 19 Dec.

Near Earth Asteroid  2015 YB will  come close to Earth on 12:08 UT 19 December at distance of 0.000395 AU (around 0.15 Earth-Moon distances). It is brightest at 12:30 UT on the 31st though. It has an estimated diameter of around 80m.

The asteroid is currently magnitude 19.0, and will be a moderately bright magnitude 13.2 at closest approach.

It is visible from both the Northern Hemisphere scopes and the SSO scopes before brightest times (around magnitude 11) but is only reasonably high above the horizon form SSO before it comes too close to the horizon.

At magnitude 10, 60 second exposures may be reasonable, shorter exposures may be too dim, at its brightest it will be moving too fast for the scopes to track.

NEO 2015 YB as seen from SSO from 21:00 pm, 10:00 UT)  19 December.  The crosses mark the position of the asteroid every 5 minutes. The large rectangle is the field of view of T12. Click to embiggen.

NEO 2015 YB moves from Orion, then through Canis Major, Puppis and beyond.

It is moving fast (1698 arc seconds/minute at its brightest), and is outside the reach of  the tracking capability of the iTelescopes at its brightest. You will need to use a topocentric ephemeris and camp out on the asteroid track in this case.

The asteroid will cross the FOV of T12 in less than 5 minutes.

There is a  large parallax effect (> 13 arc minutes at closest approach), so unless your planetarium program is able to cope with close parallax (most can't), you will need to work from topocentric coordinates.

For topocentric ephemerides go to

or JPL and choose the ephemeris link;old=0;orb=0;cov=0;log=0;cad=1#cad

Use the oobservatory code for your observatory eg  MPC Siding Spring Code Q62. Mayhill Code H06.

Always use the latest possible orbital elements and ephemeris. Note that at the moment the JPL and MPEC ephemeris do not converge, reflecting how current orbital uncertanties feed into their orbit models, you you will need to keep checking uuntil they substantaiily onverge.

JPL ephemeris for SSO at 11:00 UT (22:00 local time)  07 04 37.73 -31 18 02.5

The planning guides to viewing YU55 here and here will help organising topocentric ephemerides for close approaching NEO's.

You will need to use unguided exposures.

Choose a point where the asteroid will pass and aim at that. Remember that it takes time for the iTelescopes scopes to get to tracking position. T12 and T14 can take up to 5 minutes (depending on there being reliable stars in the field for tracking, check your logs to see what the average slew time is), so offset you initial position by around 4 minutes or so (this will be a significant distance) so the asteroid will be in field. The asteroid will cross the T12 FOV in about 5 minutes. and the T14 in around 7 minutes at its brightest approach (due to the orientation of the CCD).
