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 19 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.

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?

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 G2 MASTER (Formerly M503ujx) Close to the Helix Nebula April 19-22.

Comet C/2015 G2 MASTER (formerly M503ujx) as seen from the SSO scopes at astronomical twilight in the morning, the large rectangle is the field of view of T12, the small that of T9. Also nearby are 88P/Howell and C/2013 US10 Catalina. Click to embiggen.

The presumed comet M503ujx has been confirmed as a comet and is now C/2015 G2 MASTER (potential comet XMAAS is now C/2015 F5 (SWAN-XINGMING)). It is visible high in the eastern morning skies from the SSO scopes, being around 39 degrees above the horizon at astronomical twilight, and remains high for most of April, disappearing in mid May to reappear in the evening sky.

Between the 19th and 22nd of April the comet is within T12 distance of the Helix nebula. On the 19th it is 1 degree away from the Helix Nebula, on the 20th it will be 33' from the nebula and on the the 21st it will be 43' away.

The ephemeris lists the comet as being magnitude 11 at this time. But currently it is around magnitude 9, about 2.5 magnitudes above the ephemeris predictions. It may possibly reach magnitude 6 in mid-May evening skies, passing through Eridanus and Lepus.

The Helix Nebula is magnitude 7.9, a stack of 10-15 1 -2 minute exposures may bring them both out nicely (Rolando Ligustri may advise differently).

Maciej Reszelski has produced some preliminary orbital elements for comet M503ujx (see below). The comet currently comes to perihelion on May 21.

Despite the magnitudes listed on the map, Michael Mattiazzo suggests it may possibly reach magnitude 6 in mid-May evening skies, passing through Eridanus and Lepus, with an Earth approach of 0.47AU.

ALERT! New potential comets XMAAGS and M503ujx, Observation Requested.

There has been a flurry of new bright (ie brighter than magnitude 13) comets and potential comets discovered. Unfortunately most of them are not in a good position for iTelescope observation. The new potential comet XMAAGS is in Pegasus, and never gets high in the night sky for observation. However, M503ujx is in a good position for the SSO scopes at astronomical twilight in the morning.

Location of potential comet M503ujx as seen from the SSO scopes at astronomical twilight in the morning. At the moment it is in the same field of view as comet 88P/Howell from T12.

Currently around magnitude 11, it is 32 degrees above the eastern horizon at astronomical twilight in the morning.

ALERT! 2063 Bacchus 7 April to 25 April

Asteroid 2063 Bacchus as seen from Mayhill New Mexico from astronomical twilight from  April 7 to April 25

Asteroid 2063 Bacchus will  come close to Earth on 19:13 UT 7 April at distance of 0.195 AU (around 76 Earth-Moon distances). It is brightest between the 13th -19th though. With an estimated diameter of 1.6 Km it is one of the largest objects to get close to Earth this year.

The asteroid is currently magnitude 16.6, and will brighten to around 16.4. It's distance and leasurly brightening means there is no real hurry to catch Bacchus.

It is well placed to be visible from the Northern Hemisphere scopes initially, although it will also be visible briefly at astronomical twilight from the SSO scopes when it is brightest.

At magnitude 16 90 second exposures may be reasonable, tracking should not be an issue.

Higher power view of Asteroid 2063 Bacchus as seen from Mayhill New Mexico from astronomical twilight from  April 7 to April 12. Click to embiggen.

Asteroid 2063 Bacchus is visible for most of the month for northern scopes as it passes from Auriga to Lynx to Cancer then Leo.

The asteroid is visible from astronomical twilight until early morning for several weeks until the asteroid enters Cancer.

There is minimal paralax issues with Bacchus, and tracking will work well. The MPC one line ephemeris is
