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.

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! NEO Asteroid 2013 KB close approach on May 22

Location of NEO 2013KB as seen from the SSO observatories from 21-23 May at 3:22 pm local time. click to embiggen.

NEO asteroid 2013 KB will come within 3.2 Earth-Moon distances of us, with the closest approach of the 16 meter dimaeter asteroid on May 22 06:05 UT.

This is a Southern Scope asteroid, as it passes through Centaurus and Cricinus. It will be a difficult object to follow, not getting brighter than magnitude 18.5.

While at 3.2 LD away, paralax is not too big an issue, but it is still moving relatively fast, and the asteroid tracking may not work.

Close up chart of 2013 KB for 22-23 May, tick marks are every 1 hour. The large rectangle is the field of view of  T12  and small rectangle is the field of view of  T9. Note the parallax difference between the calculated position and the orbit. Click to embiggen.

To catch it, it's best to choose a star not far from where the asteroid would be (best use on a topocentric ephemeris, as there is still significant parallax), and set that as the target, then wait for the asteroid to zoom by.

Remember that it can take up to 5 minutes for the telescopes to slew to the imaging position, so you have to allow for this in your timing.

Up to date orbital information from the MPEC ephemeris generator is best.  If you enter the observatory code for SSO - Q62 it will create a topocentric ephemeris for Siding Spring.


ALERT! Comet 63P Wild in Outburst

Comet 63P Wild has been reported to be in outburst, rising from magnitude 15.7 on 11 May (UT) to around 12.5 on 17 May (UT). The comet is located high in the sky near Regulus for both northern and southern scopes at astronomical twilight, however, tonight it will be only 18 degrees from the waxing Moon.

May Highlights: C/2011 L4 PanSTARRS, C/2013 E2, 40 Harmonia

Last Quarter Moon is 2 May, New Moon is 10 May,  First Quarter is 18 May and Full Moon 25 May.

Comet C/2011 L4 PanSTARRS as seen from Mayhill, New Mexico at 2:30 am, on May 4. (click to embiggen)

Once again, there are several bright (ie > magnitude 12) comets in the sky at the moment, but many are in unfavourable positions.

2011 L4 PANSTARSS is the star at the moment, still bright with a beautiful detailed tail. It can now be imaged from the Mayhill telescopes in the early morning form about 2 am to Astronomical twilight (depending on the telescope T5: 15-25 degrees, T11: 15-20 degrees, T20: 15-25 degrees, T14: 20-25 degrees).

As the month goes by the comet continues to  rise and will be easier to image. Unfortunately PanSTARRS has only on reasonable encounter remaining this month.

C/2011 L4 PanSTARRS as seen at 3:30 am from Mayhill New Mexico as it passes through Cephus. The small rectangle is the field of view of T5, the medium rectangle T20 and the large rectangle T14. Click to embiggen.

On May 5 and  6 PanSTARRS is close to the open cluster NGC 110.  On May 7 it is close to the the Planetary Nebula NGC 40 (mag. 11).



C/2012 F6 Lemmon as seen at nautical twilight. The small rectangle is the field of view of T9, the medium rectangle T30 and the large rectangle T12. Click to embiggen.

Comet C/2012 F6 Lemmon is still well below the travel of the northern iTelescopes. In the southern morning sky it is just observable in the morning twilight (only 20-22 degrees at nautical twilight, with the SSO scopes going down to 20 degrees).

However there are a few encounters that make the effort worth it, on May 11 the comet is near galaxy  NGC 57 (mag.12.8). Then on the 18th is is close to the galaxies  NGC 80  and  NGC 83 galaxy (12.7 and 12.6) respectively. The on the 22nd it is close to galaxy  PGC 1467 (mag 11.5)

C/2012 L2 is too low to the horizon to be visible in the iTelescopes

Comet 2012 R1 is a nice comet at around magnitude 13, and easily visible in northern and southern hemisphere scopes in Virgo.

After all of last months action, it has no significant encounters this month.

2011 F1 (LINEAR) should have been moderately bright at magnitude 11 this month. However, it is reported that it is around magnitude 14. It is visible in the constellation Phoenix low above the horizon before morning twilight in the SSO iTelescopes.

C/2013 E2 Iwamoto as seen at astronomical twilight in the morning. The small rectangle is the field of  T30 and the large rectangle T12. Click to embiggen.

2013 E2 Iwamoto is visible in the SSO iTelescopes shortly before astronomical twilight. It is currently magnitude 13, a bit brighter than predicted.

On May 7 it is close to the galaxies NGC 7611 (mag 12.6) NGC 7619 (mag 11.1) NGC 7623 ( mag. 12.4) and  NGC 7626 (mag 11.2). On May 9 it is close to  galaxy NGC 7743 (11.2).


Asteroid 40 Harmonia crosses the face of the bright galaxy M61 (mag 9.3). This would make a nice little animation of the bright asteroid passing in front of this galaxy.
