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


Comet C/2009 F4 McNaught is Bright (mag 13.2)

Comet 2009 F4 McNaught as seen from Officer Australia. The rectangle is the field of View of the T-12 instrument (click to embiggen).

Comet C/2009 F4 McNaught has been reported to bemagnitude 13.2, a full magnitude brigher than it's MPEC prediction. The comet can be see in the Southern skies using the telescopes at Officer from astronomical twilight on. On April 30th and May 1 it will be within 10 arc minutes of the 10th magnitude globular cluster IC 4499. You can get an ephemerishere, or use the the MPEC one line ephemeris in the iTelescope input box.

May Highlights, the Virgo galaxies, Centaurus A, Pluto and Comet 2011 X1

Left - Centuarus A as seen from Officer Australia, the rectangle is the field of view of the T-12 instument (click to embiggen).

May has an abundance of wonderful subjects to image, in the South the Milky Way arches above the horizon and you are spoilt for choice, the globular cluster Omega Centauri (recently imaged by iTelescope user Gordon Mandell) but you might like to try the spectacular split galaxy Centuarus A. It is high in the southern sky around midnight, and makes for a very nice colour portrait.


Left- Virgo cluster imaged using the T-05 instrument. The B&W image is the sum of 3 x 3 minute images processed with FITS liberator (click to embiggen).

In the northern sky the Virgo cluster of galaxies are still high in the sky near midnight. This group is attractive in several instruments from the wide scal T-14 to the T-05 imager.



Left - Pluto imaged with T-05 on 17-05-2011, 2 minute exposure

Iconic Pluto is still close to M25. Pluto is currently magnitude 14, within reach of the T-05 and T-09 instruments.

Comet 2010 X1 Elenin is currently magnitude 13.7, a bit dimmer than the predicited 13.2 at this stage. It passes close to several small, magnitude 15 and 16 galaxies as it journeys through the constellation of Leo. Updated orbital elements for downloading into a planetarium program or directly into GRAS are at the Minor Planet Ephemeris Center.

Comet C/2009 F4 McNaught is currently magnitude 13.2, brighter than expected. It is only visible from the southern hemisphere near Ocatnis. On May 1st it is 8' from manitude 10 IC 4499, then on May 10 and 11 it is within 19' of the 14th magnitude galaxy PGC 49670.

Comet C/2010 X1 (Elenin) March 2011 - Feb 2012


March Highlights, Pluto and the Southern Pleiades

March is a bit light on for spectacular encounters. No comets brighter than magnitude 12 come anywhere near anything interesting. However, there are still some rather interesting objects.

left - Track of the Dwarf planet Pluto during March, as it skims above M25. Large rectangle is the field of view of the T-05 instrument, the smaller rectangle is the field of view of the iTelescope T-09 instrument (click to embiggen).

Comet 2010 X1 Elenin continues to brighten, as does2011 C1 McNaught and 2011 A3 Gibbs. Revised elements for C/20011 A3 Gibbs suggests it will not get brighter than around magnitude 15, compared with earlier estimates.

What may be interesting is imaging Pluto. Pluto is currently magnitude 14, within reach of the T-05 and T-09 instruments. Pluto is close to M25. Between the 14th and 16th Pluto is under 2 minutes of arc from the 5.6 magnitude star HD 170433. Now, imaging a faint dot may not be your cup of tea, but the historical significance of Pluto is immense. As well, a time series or animation could be quite nice. Pluto is higher in the southern skies, so you may have more luck with the instruments in Australia.

Chart of IC 2602, the Southern Pleiades. The large rectangle is the field of view of the T-14 instrument (click to embiggen).

Although not as target rich as the previous months, there are a wide variety of stellar targets available in March.

You might like to try IC 2602, the Southern Pleiades. Centred on Theta Carina, this is a large and beautiful cluster of relatively bright (magnitude 3-6) blue/white stars is set in a rich field with a pair of nice contrasting red/orange stars nearby. This is perfect set-up for the iTelescope T-14 instrument.

Unlike the Pleiades, the Southern Pleiades does not have significant nebulosity associated with it; however, there is a nice, small cluster close by in the T-12 field, Mel 101.

And, yeah. I'm late AGAIN, but err, I have been significantly distracted.


Vesta, Pluto and M25

Vesta and Pluto near M25 on the 17th-19th of February. The rectangle is the field of view of the T-14 instrument (click to embiggen).

An interesting opportunity occurs over the next few days; Vesta, Pluto and M25 are within the same field of view in the T-14 instrument. Vesta was closer to M25 and Pluto earlier, but the field was below the T-14's horizon limit.

As it is, this can only be seen with the Australian scopes, where Vesta is 25 degrees above the horizon at astronomical twilight, making this a tricky shot. As well, with Pluto at magnitude 14 and in a rich star field, picking it up will be tricky, Multiple exposures over a couple of days will be needed.

Still, the opportunity to pick up two famous dwarf planets in a nice field is  pretty good, an approach this close won't happen for many years.

On the 23rd and 24th, Vesta is close to open cluster Cr 394, could be good for a nice animation.
