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.

Support and Service

With remote astronomy observing plans can be interrupted from time to time, by clouds, wind gusts and even a rare equipment failure.

iTelescope.Net has you fully covered with our satisfaction guarantee; we will return your points if you are unsatisfied with your results. Help is just a click away. (more)

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.

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! Hubble's 1923 Nova in Andromeda Explodes Again!

The position of M31N-1923-12c plotted by the AAVSO chart plotter

The recently discovered nova in M31, M31N 2012-01b, the second novae discovered in January 2012, turns out to be a re-erruption of M31N 1923-12c, a nova discovered by Edwin Hubble on December 11, 1923. More details here.

M31N 2012-01b 1s located at R.A. = 00h 42m 38.04s; Decl. = 41deg 08' 41.7", J2000, but I haven't been able to find brightness data yet.


AAVSO Alert Notice 452: Simultaneous observations of SU Aur and AB Aur requested for XMM-Newton

AAVSO Alert Notice 452

Simultaneous observations of SU Aur and AB Aur requested for XMM-Newton
February 8, 2012

Dr. Hans Moritz Guenther, Harvard-Smithsonian Center for Astrophysics,
has requested bracketing and simultaneous observations in support
of XMM-Newton x-ray observations of the classical T Tauri 
star SU Aur and the close-by Herbig Ae star AB Aur scheduled for 
February 15 - 17, 2012. The targets are too bright to use the XMM 
optical monitor for simultaneous monitoring, so your observing 
assistance is essential for correlation of the x-ray data.

Dr. Guenther writes, "The scientific goal of the observation is to 
study the rise and decay of flares in classical T Tauri stars at 
a relatively high time resolution (less than minutes). Because T 
Tauri stars are surrounded by an accretion disk and actively accrete 
matter from the star, there is reason to believe that flares on T 
Tauri stars behave differently compared to flares on older stars 
like our sun." 

At visual magnitude ~9.5 and ~7.0, respectively, SU Aur and AB Aur 
are bright. Thus, this campaign is best suited to observers with 
smaller telescopes, as large instruments will saturate very quickly.
AB Aur is located about 3 arcmin from SU Aur, and there is a 
magnitude 7.6 comparison nearby that is suitable for both stars. 

The XMM-observations are scheduled for UT 20:31:13 2012 February 15 - 
01:27:53 February 17. Optical observations starting a few hours before 
and lasting a few hours longer would be ideal, but the main focus is 
the time of the XMM-Newton observation. SU Aur flares often and Dr.
Guenther expects it will exhibit optical brightening. 

Photometry should be carried out with exposure times of 1 minute 
or less (and timing of the telescope clock accurate to the same 
level). V filter is preferred but any filter is acceptable. 
Unfiltered observations are not recommended as both stars are red.
It would be helpful if the filter and zero point were calibrated, 
but since Dr. Guenther is most concerned about relative changes, 
it is not required.

Nightly observations are also requested from now through February 
24 to provide a good context for the simultaneous and bracketing 

Coordinates (2000.0):
SU Aur R.A. 04 55 59.38  Dec. +30 34 01.5
AB Aur R.A. 04 55 45.84  Dec. +30 33 04.3

Charts may be created using VSP (

Please report observations to the AAVSO International Database 
using the names SU AUR and AB AUR.

Your observations are crucial to the success of this campaign!
Many thanks!

P/2003 T12 = 2012 A3 (SOHO).

I wrote a little while ago of the fantastic cooperative effort from the STEREOHUNTERS that lead to the recovery of comet P/2003 T12. The Minor Planet Center has assigned the recovered comet the identifier 2012 A3 (SOHO). It's predicted magnitude is around 12, Hidetaka Sato may have picked it up, and Comet Al, who first detected it in stereo images, has picked it up deep in the twilight with T11. It will be a difficult object for some time as it climbs out of the twilight, but will be interesting to follow.


ALERT! Asteroid 433 Eros Has a Rare Close Approach

Asteroid 433 Eros, the fist asteroid to be orbited by a spacecraft, is normally very faint as seen from Earth, but roughly every 10 years or so it gets close enough for it to be relatively bright. Between 30 Jan and 6 Feb this asteroid will be a reasonably easy magnitude 8.4, as it comes to within 0.178 AU of Earth.

While it will be no more than a dot, it is an iconic asteroid, so it will be well worth a shot or two, maybe an animation as it passes through Sextans (sadly, not passing anything really interesting). It transits at around 2am - 1 am over this time.

As always, up to date ephemeredes can be obtained from the MPEC.
