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.

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.


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.

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! 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.

Ephemeris of M503ujx for SSO (MPC observatory code Q62) derived from the Possible Comet Confirmation Page

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

ALERT! Bright Potential Nova in Sagittarius, Observation Resquested.

Chart of the location of the bright nova recently reported in Sagittarius as seen from the SSO scopes.The lage rectangle is the field of view of T12 and T20, the small that of T9. Click to embiggen.

The nova is best seen from the SSO observatories from around 3:00 am local time until astronomical twilight in the morning, the nova is imageable  from the northern hemisphere scopes at astronomical twilight. The nova should be readlily recognisable in the field of relatively dimmer stars.

Hot on the heels of two bright nova in Scorpius and Sagittarius, another bright, and I mean REALLY bright, possible nova, last reported magnitude 5.3, has been reported in Sagittarius.

PNV J18365700-2855420's location is R.A. 18 36 57.00 Decl. -28 55 42.0  (J2000.0). The CBAT report page is here

ALERT! The Ghost Comet C/2015 D1 SOHO, C/2015 C2 (SWAN) and Comet 29P, Observations Requested

Comet C/2015 D1 (SOHO) and C/2015 C2 (SWAN) predicted paths as seen from Mayhill New Mexico. Click to embiggen.

Comet C/2015 D1 SOHO was a sungrazing comet that survived close passage to the Sun, only to disintegrate later.

People have been trying to follow the debris, evocatively called the "Ghost Comet" by Sky and Telescope, as it continues on the comets orbit.

As of March the 7th, the potential debris cloud will be higher enough for iTelescope instruments to catch it (northern scopes only) after astronomical twilight, and the Moon will be out of the sky.

Here is Seiichiro Kiyota's  image of the comet debris on March 6 with T14!

The comet debris trail  is only visible  briefly at astronomical twilight and  it will be quite dim (possibly magnitude 11-12). The MPC ephemeris is here:

    CK15D010  2015 02 19.7471  0.028115  1.000000  234.7391   96.0501   70.2855  20141209  9.0  4.0      C/2015 D1 (SOHO)

Comet C/2015 C1 is the official name of the Comet ROB001 discovered in the SOHO SWAN images by Rob Matson and Michael Mattiazzo, and confirmed by Terry Lovejoy. It is too low for any of the iTelescopes, but will become visible from around March 27 on, probably around magnitude 12.

The MPC ephemeris is here:

    CK15C020  2015 03 04.6452  0.708887  0.979790  334.2780   49.6191   94.6959  20141209  14.0  4.0      C/2015 C2 (SWAN)

Comet 29P/Schwassmann-Wachmannas seen from the SSO scopes at 3:30 am local time Click to embiggen.

Comet 29P/Schwassmann-Wachmann has been reported to be in outburst, brightening to around magnitude 14.

Currently in Sagittarius, it is high enough for imaging from around midnight for the Southern iTelescopes and astronomical twilight from the northern iTelescopes. Please pass any observations on to comets-ml, comet-obs or the Comet Observation Database.
