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.

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.

A dedicated team of professionals are working around the clock to keep the network operating. This includes local ground crews at each observatory, sophisticated monitoring systems and remote observatory administrators monitoring the quality of data coming off the network.

Our dedicated support website allows members to seek answers to frequently asked questions. Formal support can be requested by lodging a support ticket, which can be viewed, tracked and managed through to completion. Go to or simply email

Our contact details are also available. You can phone or Skype us if you want to speak to a person directly; you can also contact us via Skype instant message, email and fax.

How much does this cost?

Rates vary based on your membership plan and the phase of the moon. Rates start as low as 17 to 100+ points per imaging hour, which is billed per minute of imaging time used; typically one point equals $1. Make sure you are subscribed to our newsletter for special offers. Please visit our pricing page for more information on telescope operating rates. (more)

Each telescope has its imaging hourly rate displayed in real time in the launchpad before you login. At the end of each session you are also sent a detailed usage receipt which includes the costs, weather data, preview jpeg images and your observing session log file.

Membership Plans

We have a range of plans catering for everyone from the amateur to the professional astronomer. Each plan provides unrestricted access to each telescope and includes the plan’s dollar value in points, which is credited to your account each time the membership renews. (more)

Membership plans set the usage rates for each telescope on the network, expressed in points per operating hour. The entry level plans provide maximum flexibility on our single shot colour systems, and the heavy usage plans focus more on the large research grade systems. Memberships start from $19.95 and range to $999.95 per 28 day period.

Additional points can be purchased at any time to supplement your account balance.

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! URGENT Photometry urgently required for "Tabby's Star" KIC 8462852

Location of Tabby's star, other wise known as Boyajian's Star, KIC 8462852and TYC 3162-665-1 as seen from Mayhill, New Mexico. The 12th magnitude star is in Cygnus, approximately between alpha and delta Cygni. The field of view of Y05 is indicated, click to embiggen.

Photometry is urgently required for "Tabby's Star", (TYC 3162-665-1, KIC 8462852). Originally identified by by Tabetha Boyajian in the Kepler data it is most intriguing because of larger irregular dips in brightness which could not be explained by exoplanets.

The reasons for this are unclear, and everything from disintegrating cometary clouds and alien megastrucures have been proposed. Now the first significant fall in brightness since 2015 is occuriing (see here for magnitude chart), more details are in this astronomers telegram.

Observations are urgently required to follow this dimming in multiple wavelengths. Full details of what is required for observations are here . The AAVSO also have magnitude comparison charts to follow the star over this dimming.

The star is in Cygnus approximately between alpha and delta Cygni. It is only observable from Northern Scopes, between 1:30 am local time to astronomical twilight at around 4:00 am.

Coordinates (J2000):  RA 20 06 15.46 , Dec +44 27 24.8






ALERT! Observations Requested for Bizarre Kepler Star KIC 08462852

Location of KIC 08462852 from Mayhill NM at astronomical twilight. 30 Cyg is shown for orientation with the medium resolution map. Click to embiggen.

The inter tubes have been in uproar about the Kepler star KIC 08462852, a star with highly unusual dips in light intensity.  The Kepler probe was designed to find extrasolar planets by watching for the minute dips in a stars light as a planet crosses in front of it.

KIC 08462852 is highly unusual in that it has quite strong decreases in light intensity, far deeper than a Jupiter-style planet would produce, and the dips can last several days.

Bizarrely, the dips in the light are asymmetric and aperiodic, with dips occurring anywhere between 20 days apart to over a year apart (500 days).

Medium resolution finder chart chart of the  location of KIC 08462852, 30 Cyg and TYC 3559-2126-1 are show for orientation, the rectangle is the field of view of T5 and T17. Click to embiggen.

Various explanations have been tried, and rejected for this behaviour, the leading one being a swarm of evaporating comets. However the public imagination (or at least the imagination of the tabloids), was caught by the (unlikely) possibility that this represents the signature of an orbiting alien megastructure.

Whatever is the explanation, continued examination of this fascination star is required.

Observations have been requested by the AAVSO for KIC 08462852 in multiple bands, at least V and B, in order to try and work out the source of the variability.

High resolution finder chart chart of the  location of KIC 08462852, TYC 3559-2126-1 is shown for orientation with the medium resolution map, the rectangle is the field of view of T5 and T17. Click to embiggen.

KIC 08462852 is reasonably bright, magnitude 11.88, and should be well suitable for imaging with 30-60 second exposures (around 10 exposures should be enough for a good determination). Peter Lake has used 30 second images to profile this star.

The coordinates of KIC 08462852 are (J2000):  RA 20 06 15.46 , Dec +44 27 24.8. The star seems to be identical to TYC 3162-665-1.

You will need to have images from stars of known magnitude for comparison I have included the AAVSO magnitude comparison map as well for ease of use (click to mebiggen), or you can get it via the AAVSO start plotter.

Please promptly report all observations to the AAVSO International Database using the name "KIC 8462852"; please note the space between "KIC" and the identifier which is required for submission.
