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.

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! Supernova in NGC 428

A bright supernova, magnitude  12.2 has been reported in NGC 428 by Stu Parker (discovery image here), details here

RA 01:12:54.92 Dec +00:58:45.7 PSN J01125492+0058457


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.


ALERT! Follow up of Gamma Ray Burster GRB 130427A

The Swift and Fermi orbital telescopes observed an astonisingly bright Gamma Ray Burster on April 27, GRB 130427A. This was follwed by a record number of ground based telescopes, including amateur scopes (see optical light curve here).

It is too faint to follow at the moment, but, at about 3.6 billion light-years away this GRB is relatively close, and there is a good chance that an underlying supernova will be observed.

Astronomers estimate that the supernova should become apparent by mid month, if one develops. Thus the supernova observers in the iTelescope members may be interested in extended follow-up to catch the supernova on the rise.

The location of GRB 130427A is RA(J2000) = 11h 32' 32.84", Dec(J2000) = +27d 41' 56.2" with an uncertainty of 1" (Elenin et al', GCN 14450)


ALERT! Supernovae in NGC 7331 and PGC 50171

Two new Supernovae have been discovered (and confirmed) that may be of interest to iTelescope users.

The first is SN 2013bu (PSN J22370217+3424052), a type II supernova in NGC 7331 (called the twin of the Milky way). Currently magnitude 15.5, it has the potential to become as bright as magnitude 11. Location RA: 22 37 02.17 Dec: +34 24 05.2 (Hat tip to Leonid Elenin)

The second is SN 2013bj (PSN J14041963-0703069),a type II supernova in PGC 50171. Currently magnitude 18.8, it was confirmed by its discoverer Simone Leonini using iTelescope T21. RA: 14 04 19.63 Dec: -07 03 06.9 (Hat tip to Peter Lake on Club on Facebook)
