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.

"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


Comet C/2012 S1 ISON comes into view

Chart of Comet C/2012 S1 ISON as seen from New Mexico at astronomical twilight (5:22 am) on September 15.

iTelescope user Seiichiro Kiyota has imaged comet C/2012 S1 ISON using the modestly sized iTelescope T4. This is a significant feat as the comet is only just in T4's lower limit of travel at nautical twilight.

The comet remains in nautical twilight until the 15th of September, when it finally makes astronomical twilight at the lower limit of T4 and T5 telescope travel (it is never in the view of the SSO scopes at or before nautical twilight).

Observations during this time are crucial to understanding the development of this comet, over-hyped as the "comet of the century" in some quarters. despite the hype it will, provided it doesn't disintegrate before perihelion, be one of the brightest comets for some years, possibly rivalling or exceeding C/2006 P1 McNaught. This is a wonderful opportunity for amateur astronomers to contribute to comet science through our observations of this comet on it's first escursion through the inner solar system from the Oort cloud.

During late September and all of October the comet will be in a good position for imaging, although never higher than 40 degrees above the horizon at astronomical twilight. The comet comes close to Mars (and Spica) from our perspective on October 16, although at possibly magnitude 8.5 imaging it and bright Mars together will be a challenge.

(Hopefully) rapidly brightening ISON remains above the iTelescopes filed of travle at astronomical twilight until 13 November, and rapidly passes beyond the limit of travel at nautical twilight soon after.

Shortly after this the comet reaches perihelion (28 November), and then we will have to wait to see if it disintegrates, or provides us with a spectacle as it returns from the Sun.


ALERT! Close approach of NEO 2013 QR1 August 25

NEO 2013 QR1 will make a close approach to Earth on August 25, 19:31 UT. The 215 meter diameter rock will come within 9 Earth - Moon distances. The Asteroid is moving at greater than 100"/ second, and is only brighter than magnitude 16 for a short while. The SSO scopes have the best view. 

You will need to generate at topocentric ephemeris using the MPC and the scopes observatory codes (I'm doing this on my iPad, so you have to look at the 1999 CF9 post for links and codes). The NEO wil cross the FOV of T9 in 5 minutes, and it takes about 4-5 minutes for the scopes to slew to position, so you will need to account for that in your setup.;orb=1;cov=0;log=0;cad=1#cad



ALERT! NEO Asteroid 1999 CF9 close approach on August 23

NEO 1999 CF9 as seen from New Mexico at 9:06 pm 22-24 August (03:06 UT 23 August - 25 August) . The crosses mark the position of the asteroid every 5 hours, click to embiggen.

Near Earth Asteroid  1999 CF9 will  come close to Earth on  August 23 at 00:28 UT at distance of 0.06 AU (around 25 Earth-Moon distances). It has an estimated diameter of  1.1 km. The asteroid is currently magnitude 14.8, and will be mag 14.8 at closest approach. It then brightens to 14.5 as it moves away. 60 second images will be reasonable when it is around mag 15, 30-10 seconds for 14.5 and brighter.

NEO 1999 CF9 is visible from all the iTelescopes as it passes through Serpens and Ophiuchus. The asteroid is higest from the Southern Scopes. It is moving moderately  fast (24.5"/min), and may be just in reach of  the tracking capability of the iTelescopes. You may need to use a topocentric ephemeris and camp out on the asteroid track.

The asteroid is high enough to image from around astronomical twilight from Mayhill, Serpio and SSO. All miss closest approach, but Mayhill is closest to closest approach (oocurs 3 hours before astronomical twilight.

Close up view of 1999 CF9 on the night of the 23rd from 9:06 pm Mayhill. 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 (chart generated with SkyMap pro, click to embiggen).

There is modest parallax effect (98"), 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

Nth America MPC Code - H06, Spain MPC Code - I89, Siding Spring CodeQ62

Always use the latest possible orbital elements and ephemeris. The planning guides to viewing YU55 here and here will help organising topocentric ephemerides  for close approaching NEO's.

You will probably 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. T14 and T12 can take up to 5 minutes (depending on there being reliable stars in the field for tracking), so offset you initial position by around 4 minutes or so (this will be a significant distance) so the asteroid will be in field.
