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 19 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.


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

ALERT! The Ghost Comet C/2015 D1 SOHO, C/2015 C2 (SWAN) and Comet 29P, Observations Requested

Comet C/2015 D1 (SOHO) and C/2015 C2 (SWAN) predicted paths as seen from Mayhill New Mexico. Click to embiggen.

Comet C/2015 D1 SOHO was a sungrazing comet that survived close passage to the Sun, only to disintegrate later.

People have been trying to follow the debris, evocatively called the "Ghost Comet" by Sky and Telescope, as it continues on the comets orbit.

As of March the 7th, the potential debris cloud will be higher enough for iTelescope instruments to catch it (northern scopes only) after astronomical twilight, and the Moon will be out of the sky.

Here is Seiichiro Kiyota's  image of the comet debris on March 6 with T14!

The comet debris trail  is only visible  briefly at astronomical twilight and  it will be quite dim (possibly magnitude 11-12). The MPC ephemeris is here:

    CK15D010  2015 02 19.7471  0.028115  1.000000  234.7391   96.0501   70.2855  20141209  9.0  4.0      C/2015 D1 (SOHO)

Comet C/2015 C1 is the official name of the Comet ROB001 discovered in the SOHO SWAN images by Rob Matson and Michael Mattiazzo, and confirmed by Terry Lovejoy. It is too low for any of the iTelescopes, but will become visible from around March 27 on, probably around magnitude 12.

The MPC ephemeris is here:

    CK15C020  2015 03 04.6452  0.708887  0.979790  334.2780   49.6191   94.6959  20141209  14.0  4.0      C/2015 C2 (SWAN)

Comet 29P/Schwassmann-Wachmannas seen from the SSO scopes at 3:30 am local time Click to embiggen.

Comet 29P/Schwassmann-Wachmann has been reported to be in outburst, brightening to around magnitude 14.

Currently in Sagittarius, it is high enough for imaging from around midnight for the Southern iTelescopes and astronomical twilight from the northern iTelescopes. Please pass any observations on to comets-ml, comet-obs or the Comet Observation Database.

ALERT! Comet C/2015 D1 SOHO, ROB001 (SOHO SWAN) and Comet C/2013 C2 Tengagra, Observations Requested

Comet C/2015 D1 (SOHO) predicted path as seen from Mayhill New Mexico. The rectangle is the field of view of T14. Click to embiggen.

Comet C/2014 SOHO is a sungrazing comet that breifly reach magnitude 4 and survived close passage to the Sun, at least until it was out of the FOV of the SOHO C3 instrument.

Currently people are trying to recover it along its predicted path, however, because the orbital elements are from spacecraft observations, there may be a fair bit of error. Also the comet is very low to the horizon.  To date, the comet has not been recovered and is likely to be dimmer than magnitude 9.

The comet is only accessible for northern hemisphere instruments, and will not be in view of the iTelescopes at astronomical twilight until around 4 March, when it will have dimmed a fair bit (possibly magnitude 11-12). The MPC ephemeris is here:

    CK15D010  2015 02 19.7471  0.028115  1.000000  234.7391   96.0501   70.2855             9.0  4.0      C/2015 D1 (SOHO)

Comet ROB001 Comet ROB001 is a new comet discovered in the SOHO SWAN images by Rob Matson and Michael Mattiazzo, and confirmed by Terry Lovejoy. Sadly, while it is close to the star Beta Ceti, it is too low for any of the iTelescopes, and unlikely to become visible until after perihelion in April. You can generate your own elements here.


Comet C/2013 Tengara has been reported to be in outburst by the SLOOH robotic observatory, brightening from magnitude 19 to around magnitude 16. Currently in Corvus, it is high enough for imaging from around midnight. Please pass any observations on to comets-ml, comet-obs or the Comet Observation Database.

ALERT! Bright Nova in Scorpius and Sagittarius, Observation Resquested.

Chart of the location of the two nova recently reported in Scorpius and Sagittarius. The Nova are best seen from the SSO observatories shortly before astronomical twilight in the morning, the nova are too close to the horizon from the northern hemisphere scopes. Click to embiggen.

Two bright nova have been reported. The first in Scoripus, was reported at magnitude 8.4 but has rapidly faded to magnitude 10.6

It's location is R.A. 17 03 26.20 Decl. -35 04 14.0  (J2000.0). The AAVSO alert page is here

Please report magnitude and any spectra to the AAVSO, see this link for information:

A bright transient has also been spotted in Sagittarius. It's starting magnitude was 10.9.

RA: 18 14 25.24 , Dec: -25 54 32.6 (J2000)

The potential nova is in a crowded field, so you may need the AVSO spotting maps to be certain you are seeing the object. Details can be found here.

Please submit observations as before.



ALERT! Comet 17P/Holmes in Outburst, Observations Requested

Location of comet 17P/Holmes in Perseus at 20:00 from Mayhill New Mexico at telescopic scale. The large rectangle is the field of view of T20, the small that of T5, T11 is in-between.Click to embiggen

Comet 17P/Holmes is reported to be in outburst, with an increase in magnitude of around 3.7 to magntiude 14.3, with a wedge shaped coma.

Observations are requested to follow the evolution of this outburst, especially over the next few days to follow the coma expansion. 

Please pass any observations on to comets-ml, comet-obs or the Comet Observation Database.

The comet is currently in Perseus near epsilon Persii, not far from the Zenith at astronomical twilight. The comet transits at 19h 33m 12s and sets at 4h 4m 49.Thus it is only visible from the northern scopes, but is visible under good conditions for most of the night. Unfortunaetly the waxing Moon will hamper observation somewhat, and the comet is too low to image at Moonset.
