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.

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! Observations of comet 67P request to support a HST campaign

Chart of the location of comet 67P at astronomical twilight (4:57 pm local time) as seen from Mayhill NM. The comet is observable form Northern Hemisphere scopes only, and is within iTelescope range from 3:30 am (25 degrees above the horizon) unil astronomical twilight (43 degress above the horizon). Click to embiggen.

Observations of comet 67P are requested to support a HST Polarimetry Observations compaign scheduled for November 9, 10 and 11. People have been requested to be monitoring activity on those days.

All observations are welcome, but deep imaging, narrow band (including R, B  and V) imaging and dspectroscopy would be very valuable. Those who are not already members of the PACA_Rosetta group can email me for more deatils of how to submit images.

ALERT! Observations Requested for V5668 Sgr (Nova Sgr 2015 No. 2)

Location of V5668 Sgr (Nova Sgr 2015 No. 2) as sen from the SSO Scopes at astronomical twilight. At the end of astronomical twilight in the evening Nova Sag 2 is 40 degrees above the horizon from the SSO scopes and too low for the northern hemisphere sopes. Click to embiggen.

Coordinates: R.A. 18 36 56.84   Dec. -28 55 39.8  (2000.0)

The AAVSO has requested observations of V5668 Sgr (Nova Sgr 2015 No. 2) in support of Hubble Space Telescope observations of the nova.

Observations are needed of brightness ahead of the Hubble observations to set the correct exposudre to quote the AAVSO.

"The STIS observation will be carried out on 2015 November 6 around 01 hour UT. Beginning immediately, observers are requested to observe V5668 Sgr in B, V, and SDSS g' bands. Because the spectra will be taken in the UV and far UV regions, the bluer the monitoring band, the better; B photometry will be particularly valuable. Visual observations are also welcome. Nightly observations are requested through November 13; time series observations are not necessary."

ALERT! Observations Requested for Bizarre Kepler Star KIC 08462852

Location of KIC 08462852 from Mayhill NM at astronomical twilight. 30 Cyg is shown for orientation with the medium resolution map. Click to embiggen.

The inter tubes have been in uproar about the Kepler star KIC 08462852, a star with highly unusual dips in light intensity.  The Kepler probe was designed to find extrasolar planets by watching for the minute dips in a stars light as a planet crosses in front of it.

KIC 08462852 is highly unusual in that it has quite strong decreases in light intensity, far deeper than a Jupiter-style planet would produce, and the dips can last several days.

Bizarrely, the dips in the light are asymmetric and aperiodic, with dips occurring anywhere between 20 days apart to over a year apart (500 days).

Medium resolution finder chart chart of the  location of KIC 08462852, 30 Cyg and TYC 3559-2126-1 are show for orientation, the rectangle is the field of view of T5 and T17. Click to embiggen.

Various explanations have been tried, and rejected for this behaviour, the leading one being a swarm of evaporating comets. However the public imagination (or at least the imagination of the tabloids), was caught by the (unlikely) possibility that this represents the signature of an orbiting alien megastructure.

Whatever is the explanation, continued examination of this fascination star is required.

Observations have been requested by the AAVSO for KIC 08462852 in multiple bands, at least V and B, in order to try and work out the source of the variability.

KIC 08462852 is reasonably bright, magnitude 11.88, and should be well suitable for imaging with 30-60 second exposures (around 10 exposures should be enough for a good determination). Peter Lake has used 30 second images to profile this star.

The coordinates of KIC 08462852 are (J2000):  RA 20 06 15.46 , Dec +44 27 24.8. The star seems to be identical to TYC 3162-665-1.

You will need to have images from stars of known magnitude for comparison I have included the AAVSO magnitude comparison map as well for ease of use (click to mebiggen), or you can get it via the AAVSO start plotter.

Please promptly report all observations to the AAVSO International Database using the name "KIC 8462852"; please note the space between "KIC" and the identifier which is required for submission.

ALERT! Bright NEO 2015 TB145 on 29-31 October, 2015

Newly discovered NEO 2015 TB145 as seen from Mayhill New Mexico from Astronomical twilight (4:55 am, 12:00 UT) 29 October - 31 October. The crosses mark the position of the asteroid every 2 Hours.

Near Earth Asteroid  2015 TB145 will  come close to Earth on 16:18 UT 31 October at distance of 0.003 AU (around 1.3 Earth-Moon distances). It is brightest at 12:30 UT on the 31st though. It has an estimated diameter of around 460m.

The asteroid is currently magnitude 19.5, and will be a reasonably bright magnitude 10.1 at closest approach.

It is visible from the Northern Hemisphere scopes for most of the time.  It will be visible from SSO scopes before brightest times (around magnitude 11) until astronomical twilight on the morning of the 31st local time.

At magnitude 10, 60 second exposures may be reasonable, shorter exposures may be too dim, at its brightest it will be moving too fast for the scopes to track.

NEO 2015 TB145 as seen from Mayhill New Mexico from Astronomical twilight (4:55 am, 12:00 UT) 30 October - 31 October.  The crosses mark the position of the asteroid every 30 minutes. The large rectangle is the field of view of T14. Click to embiggen.

NEO 2015 TB145 moves from Taurus to Orion, then back into Taurus (crossing the horns of the Bull) into Auriga (wehre it is brightest) then on to Lynx and beyond.

For the Northern Hemisphere scopes the asteroid is visible from around 10 pm to astronomical twilight in the morning. This allows observers to catch the NEO at its brightest.

It is moving fast (398.15 arc seconds/minute at its brightest), and is outside the reach of  the tracking capability of the iTelescopes at its brightest (closest approach, when it is even faster, is in daylight). You will need to use a topocentric ephemeris and camp out on the asteroid track in this case.

There is a  large parallax effect (> 30 arc minutes at closest approach), so unless your planetarium program is able to cope with close parallax (most can't), you will need to work from topocentric coordinates.

For topocentric ephemerides go to

 MPC Siding Spring Code Q62. Mayhill Code H06.

Always use the latest possible orbital elements and ephemeris. Note that at the moment the JPL and MPEC ephemeris do not converge between the 29th and 1st Nov, reflecting how current orbital uncertanties feed into their orbit models, you you will need to keep checking uuntil they substantaiily onverge.

JPL ephemeris for astronomical twilight 31st      06 10 13.22 +32 21 01.1

MPEC ephemeris for astronomical twilight 31st  05 44 46.8 +26 28 06

The planning guides to viewing YU55 here and here will help organising topocentric ephemerides for close approaching NEO's.

You will need to use unguided exposures.

Choose a point where the asteroid will pass and aim at that. Remember that it takes time for the iTelescopes scopes to get to tracking position. T12 and T14 can take up to 5 minutes (depending on there being reliable stars in the field for tracking, check your logs to see what the average slew time is), so offset you initial position by around 4 minutes or so (this will be a significant distance) so the asteroid will be in field. The asteroid will cross the T12 FOV in about 20 minutes. and the T14 in around 30 minutes at its brightest approach (due to the orientation of the CCD).
