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


The First Comet of 2012 ... C/2012 A1 (PANSTARRS). The comet is currently in Lynx at magnitude 19.8, it is at perihelion on 11 March 2014, and doesn't exceed magnitude 18.3 at its predicted brightest, when it is 6.9 au away. Use the aquire comet NEO dialog and the one-line MPEC elements.

CK12A010  2014 03 11.8930  6.881843  1.000000  203.2278  279.2941  118.9291             6.0  4.0      C/2012 A1 (PANSTARRS)


ALERT! Comets C/2009 P1 (Garradd) C/2011 W3 (Lovejoy) and a bunch of new comets.

Comet C/2009 P1 (Garrad) is once more in range of the northern GRAS/iTelescope scopes, just before astronomical twilight in the morning . Roughly around magnitude 7, it shows two distinct tails almost at 90 degrees to each other (image from Gerald Rhemann here).

The Christmas comet C/2011 W3 (Lovejoy) has entered the field of view of the Australian GRAS/iTelescope scopes in the early morning. It's visual magnitude is around 6.5 or so and rapidly dropping. If the appalling weather we have here clears up there should be some great images to be had. The Astronomical Society of Victoria has a great image gallery here.

Both C/2009 P1 and C/2011 W3 will be strongly affected by moonlight after the 9th until around last quarter on the 16th.

Congratulations to Andrea Boattini who  has discovered two new comets, C/2011 Y2 and Y3 (Boattini), on the 24th and 25th of December (another, if somewhat faint, Christmas comet). Both are rather faint and fading, neither will exceed magnitude 17.

Comet C/2011 UF305 (LINEAR) was a NEO which has been reclassified as a comet. In May it will reach magnitude 14.5, travelling through Cephus and Camoleopardis.

Comet C/2011 U3 (PANSTARRS) will be at it's brightest when travelling through the Southern skies in June. However, there is a big discrepancy between the MPEC ephemeris value for the magnitude (14.0) and the JPL horizons ephemeris (9.0). JPL prdictions are typically slighly higher than  MPEC predictions, I would bet on the MPEC vaue being correct.


ALERT! Comet C/2010 G2 (Hill) is in Outburst

Alfons Diepvens (Olmen, Belgium MPC:C23) and confirmed by Erik Bryssinck has reported an outburst of C/2010 G2 (HILL). The comet is reported to have increased by 1.84 magnitude in a couple of days. Recent images from Rolando Ligustri using GRAS-11 are here.

Inserting the one-line MPEC elements into the comet/NEA dialog is the best way to image this comet.


December Highlights, NGC 1404 supernova, 78P, C/2010 G2 (Hill) and more

The Full Moon was December 11, and will again be full on the 9th of January. For now we have excellent dark skies, with First Quarter Moon on 1 Jan beginning to interfere with the evening comets.

 Comet 78P/Geherels has left Uranus behind. At around magnitude 11 it makes a nice target. An early evening object, it is best imaged between astronomical twilight and 10:20 pm, when it is too low for the GRAS scopes. 

Left image, chart of 78P form December 28 to December 3, the small rectangles are the field of view of the GRAS-05/04 instruments, the large rectangle is the FOV of GRAS-20. Click to embiggen.

On December 28 Comet 78P/Geherels is close to the magnitude 12 galaxies NGC 125 and 128 and the magnitude 13 galaxy NGC 132. you will need multiple frames in G05 or G04 to catch them, but they fit neatly into the FOV of G20 (G14 is a tad too wide for the fainter galaxies to come out well). From January 1 to 3 the comet is close to a number of small dim galaxies as well as the 12th magnitude NGC 194 and 173. These fit neatly into the GRAS 20 FOV and some judicious juggling can create overlapping files with the narrower FOV instruments.

Comet C/2010 G2 Hill is currently brighter than predicted (around magnitude 10, it is quite high in the early evening sky, and will be a good target for the rest of December early January before moonlight interferes. It has no really interesting encounters until 31 December, when it is close to 13th magnitude NGC 1218.

Comet C/2011 W3 Lovejoy is only visible in the southern GRAS scopes, and does not get high enough above the horizon to image until around January 2. Exactly how bright it will be is currently unknown. On January 3 it will be in GRAS-14 range of the globular cluster NGC

Comet C/2009 P1 Garrad is still bright, but doesn't come into the field of view of the GRAS scopes until January 3. When it will be around magnitude 7, it doesn't have any really interesting encounters before full Moon.

Supernova 2011iv in NGC 1404 taken with GRAS-12 on December 11 2011, 5x60 second luminance exposures stacked and summed using ImageJ. Compare with images here and here.

Supernova 2011iv, in NGC1404 in Fornax, is still bright at around magnitude 12.4. It is also only visible from GRAS Southern scopes.
