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 13 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 half metre (20”) 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.


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)

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! Bright Supernova in M74

A bright supernova 2013ej, has been confirmed in the galaxy M74. Interestingly, it is not far (less than one arc second) from the position of a supernova in M74 found in M74 by iTelescope member Stan Hunt (SNHunt142).

A confirmation image using one of the SSO iTelescopes is here.

The waning Moon has now moved away from M74, making it an excellent target.


ALERT! NEO Asteroid 2003 DZ15 close approach on July 30

NEO 2003 DZ15 as seen from New Mexico at 10:00 pm 28-31 July (04:00 UT 29 July- 1 August) . The crosses mark the position of the asteroid every 5 hours.

Near Earth Asteroid  2003 DZ15 will  came close to Earth on  July 30 at 00:47 UT at distance of 0.02 AU (around 9 Earth-Moon distances). It has an estimated diameter of  152 m. The asteroid is actually getting dimmer, currently magnitude 16.7 it reaches mag 18 at closest approach. The dimness will make this a bit of a challenge.

NEO 2003 DZ15 is only visible from the northern iTelescopes as it passes through Lyra, Draco and Ursa Major. It is moving moderately, so the tracking capability of the iTelescopes may be okay, but topocentric epheri would be best to make sure.

The asteroid is high enough to image from astronomical twilight to around midnight from Mayhill.

Close up view of 2003 DZ15 on the night of the 29th (30th UT). Each time point is 15 minutes. The Large rectangle is the field of view of iTelescope 14, small rectangle is the field of view of iTelecope 5.

While standard planetarium plotting may be sufficent, you may still like to work from topocentric coordinates. For topocentric ephemerides go to

ALERT! NEO Asteroid 2001 PJ9 close approach on July 17 -July 20


NEO 2001 PJ9 as seen from New Mexico at 1:30 am 19 July (07:31 UT) . The crosses mark the position of the asteroid every hour.

Near Earth Asteroid  2001 PJ9 came close to Earth on  2013-Jul-17 at 23:08UT at distance of 0.075 AU. This rock has an estimated diameter of  800 m. The asteroid is getting brighter and reaches mag 15.7 over next 5 days.

Astrometry is needed to support Goldstone radar observations.

NEO 2001 PJ9 is only visible from the northern iTelescopes as it passes through Cassiopeia, Andromeda and Lacerata. It is moving relatively slowly, so the tracking capability of the iTelescopes should be all that is needed.

The asteroid rises around 20:00 from Mayhill, and is only decently high enough to image at around 1-1:30 am.

Close up view of 2001 PJ9 on the night of the 19th. Each time point is one hour. . The rectangle is the field of view of iTelecope 5.
