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.

iTelescope News & Updates 


System Optics Changes Upcoming

Major changes are incoming for two of the Planewave Systems in the next few days in the form of (0.66) Focal Reducers. (Update - T11 has the new reducer fitted already.)

These are optical reducers designed specifically for flat field telescopes like the CDK. They reduce the f ratio of the CDK telescope by around 34%. The f/6.8CDK17 (iT-17) and CDK20 (iT-11) telescopes will be reduced to about f/4.5.

G17 FOV - No Reducer FittedThis allows for faster/deeper imaging because of the brighter targets and a slightly larger field of view (FOV). It makes guidance slightly more forgiving, even though these telescopes really have no problems with guiding. In fact G11 has had its guidance disabled since its brilliant Planewave Ascension mount can go unassisted for exposures of up to 600 secs without issues!

G17 FOV - 66% Reducer Fitted

Once the new optical trains are fitted we will need to gather new calibration data, in particular the Flat Field frames. It may take a few days to fully replace the old flats data, so long as good weather allows us to carry out our normal sky flat collections at dawn and dusk. During such operations G17 can prove a difficult platform since its ultra sensitive CCD only allows us a very narrow time window for such data collection. We will also need to refresh all focusing parameters.

GiT-17 (Deep Red) is also having a filter swap done soon. It will have a Luminance filter replace its Sulfur II narrowband unit. The unusual SIII filter will remain. G17 will still have a 'pure' Clear filter, but will also have a LUM filter fitted to allow for some Infrared cutoff during long exposures.

Experience has shown us that this unique and record holding platform is prone to small internal reflections in the infrared with the Clear filter, resulting in slightly egg shaped stars that 'appear' as tracking errors. Whilst this is not a problem for science use, its not so useful for pure imaging missions. We think that some cutoff in the IR may be the solution for imagers. This telescope /CCD combo is just too sensitive in some situations!

Also of interest to iTelescope members and those that like to fully prepare for remote imaging sessions may be a small (free) software application that can show exactly what the FOV for each GRAS telescope is and gives great visual previews such as those of M42 above. CCD-Calculator

It does have extensive lists of telescope types and CCD cameras built in but you will have to manually add the newer GRAS systems such as the Planewave and new CCD cameras. (its no longer updated by the author). Its easy to do and very useful indeed. Fill out the boxes and hit ADD.

Camera details can also be found at the manufacturer web sites. The new FLI ProLine CCD for example.

More astro software suggestions can be found here.



A Southern Gem - Omega Centauri

This portrait of the night skies finest globular cluster was recently captured by Gordon Mandell. It is one of the finest images of Omega we at iTelescope have seen, and we have seen many. Gordon took this image during a bright Moon lit night downunder, thus making use of a substantial Moon Discount.

Gordon used the T9 remote telescope near Melbourne Australia to image the several million stars that are bound and revolving in Omega Centauri. Or is it a captured companion galaxy to the Milky Way? It even has its own central black hole. 15,800 light years distant and the second largest of its kind known to astronomy, it is the brightest in our skies. It has the same apparent size as a full moon!

Omega was first observed by a European in 1677 when Edmond Halley listed it as a nebula. Later in the 1830s, English astronomer John William Herschel was the first to properly identify NGC 5139 as a globular cluster.

Caught in the Act! Nova T_Pyxidis in Outburst

On April 15th Ernesto Guido & Giovanni Sosteroo of Italy's Remanzacco Observatory remotely took control of the iT-9 telescope in Australia and went hunting for a Nova in outburst as highlighted in our Alerts section.

The image posted here is the result, with their target T_Pyxidis reaching an unfiltered magnitude of approximately 8.5, way up from its usual 15.5!

Here you can see their image in an animation showing a comparison with the archived DSS plate (R Filter - 1992). This is the first outburst of T Pyx since December 7, 1966 and If it behaves as in past eruptions, it can be expected to brighten to mag 6.

This team based in Italy are extremely experienced iTelescope members and have many discoveries and amazing images of comets, NEOs and novas in their galleries. They are well worth following on Twitter if you would like to give rare object chasing a go!
