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


ALERT! Comet C/2013 X1 PanSTARRS near the Helix Nebula (4-6 June 2016)

Chart of comet C/2013 X1 near the helix nebula on 4 June UT (5 June SSO, 4 June Mayhill). The large rectangle is the field of view of T12, the medium T5 and the small T9. T14 and T20 have simar FOV's to T12, but are rotated 90 degrees. Click to embiggen.

Comet C/2013 X1 PanSTARRS is brightening and is around magnitude 6.4.

For the next few days (4 - 6 June) the comet is close to the iconic Helix Nebula. At magnitude 7.3, this low surface brightness nebula will make an excellent image with the bright comet.

The comet is closest on June 4 13:50 UT  when it is  21' 29" away, however good views will be had before and for the next two days after (in the wide FOV instruments).

The comet will be visible from both SSO and northern hemisphere scopes. However, in the SSO scopes it is in reach of the scopes travel from 1:30 am to astronomical twilight, while the Mayhill scopes it is accessible just on astronomical twilight. 5 June is the best time for imaging with the SSO scopes.

This possible nova is located 2' from SAO 249214 (V= 8.7 mag) and 9' from Nova LMC 2005.

Spectroscopy is urgently required.


May Highlights: Comets C/2013 X1, 252P, C/2014 S2

New Moon is 7 May,  First Quarter 14 May,  Full Moon 22 May and Last Quarter Moon 29 May.

Chart suitable for telescope use showing the track of C/2013 X1 (PANSTARRS) as seen from SSO. The large rectangle is the field of view of T12, the small that of T9. Deep sky objects down to magnitude 13 are shown. Click to embiggen.

Comet C/2013 X1 (PANSTARRS) is now high enough to be visible. It is only visible from the SSO scopes, and is at a suitable height from around 4 am to astronomical twilight.

It is currentlty arround magnitude 7, and is showing a nice double tail reminiscent of C/2013 US10 Catalina.

The comet is in Aquarius, and passes some faint galaxies and some bright stars. Between the 13-19th it is within T12 range of the 12th magnitude galaxy NGC 7760. From the 16th to the 21st both NGC 760 and 11 th magnitude NGC 760 are in the T12 FOV together. With some careful mosaicing you can get Neptune in the picture as well.  On the 27th, the comet is 13' from 13th magnitude NGC 7443.

The path of Comet 252P as it crosses Ophiuchus into Hercules. The large rectangle is the field of view of T20, the small that of T5. Click to embiggen.

Comet 252P has faded somewhat, and is now moving more sedately, but is still a nice object. Currently around magnitude 8, it may fade very rapidly. The comet is currently in Ophiuchus and moves into Hercules, but sadly does not go past anything interesting.

The comet is best visible after 11 pm from SSO, and around 9:30 pm from the northern hemisphere scopes.

ALERT! Comet C/2015 WZ PanSTARRS Brighter than Expected

Comet C/2015 WZ PanSTARRS as seen from Mayhill New Mexico 30 minuttes before Astronomical Twilight n the morning. The large rectangle is the field of view of T14/T20, the small that of T05.

Comet C/2015 WZ has been reported to be anomalously bright. It's predicted magnitude is 17.7, but recent observations have consistently reported the magnitude brighter at between 13.5-11.5 (there is a big thread on comets-ml about its magnitude and comet magnitude measurement generally).

Suggestions range from an outburst to a meteor impact. Observations are required to follow this anomalous brightening. The comet is just north of beta Pegasii at the moment, moving towards Lacerta.

It is high enoughabove the horizon in the moring to image from 30 minutes before astronomincal twilight to astronomical twilight.
