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.

ALERT! A potential Interstellar comet C/2107 U1, Observations urgently requested

Location of comet C/2017 U1 as seen from SSO at transit (23:00 AEDST). The comet is moving quickly through Pisces.

There has been a lot of speculation that rouge comets ejected from other solar systems might pass through ours, but until now there have been no good candidates.

Comet C/2017 U1 (PANSTARRS) is currently our best candidate for an interstellar interloper with an e of ~1.2.

To quote M.P.E.C. 2017-U181

Further observations of this object are very much desired. Unless there are serious problems with much of the astrometry listed below, strongly hyperbolic orbits are the only viable solutions. Although it is probably not too sensible to compute meaningful original and future barycentric orbits, given the very short arc of observations, the orbit below has e ~ 1.2 for both values. If further observations confirm the unusual nature of this orbit, this object may be the first clear case of an interstellar comet.

Telescope view from SSO when the comet transists (around 23:00 AEST) with various illustrative FOV's, the large Square is T31, the rectangle is T11 and T5, the small square is T17. Click to embiggen (the magnitude on the chart is wrong I had to guess H and G parameters).

The good news is the comet is well placed for both northern and southern iTelescopes, it is quite high above the horizon at transit (23:00 local time SSO around 22:48 local time Mayhill) with the northern scopes having the best view. There is also a good window of observing opportunity around transit.

The bad news is that at magnitude 20 and fading, it will be a challenge to image, requiring deep sky instruments and long exposures.

ALERT! Comet C/2017 O1 ASASSNat closest approach to Earth (and a rare opportunity)

Comet C/2017 O1, discovered by the ASASSN supernova survey, as seen from the Mayhill New Mexico  scopes at transit (4:06 am, local time Mayhill).

Comet C/2017 is a surprisingly bright comet which was discovered by the ASASSN supernova survey. It is currently around magnitude 8.3, reasonably bright but well below its predicted magnitude of 7.5 at maximum.

The comet will be closest to Earth on the 18th, but will not get significantly brighter. However, this is a opportunity for an interesting and unique opportunity. Stereo imaging of the comet.

Simon White has done the work of sorting this out. I quote his recent Facebook post.

"The local constraints are as follows (based on iTelescope’s observatories in New Mexico and Nerpio):

➤ In the USA, 2017 O1 will be rising in the 18 October evening sky. At 2200 in New Mexico, it will have reached 27° and will continue to rise with Camelopardalis (confirmed - IFM).

➤ In Europe, 2017 O1 is high, almost at zenith, in the pre-dawn sky of 19 October, so elevation is not a constraint. At 2200 18 October in New Mexico, clocks in Spain will be at 0600 19 October, in the last hour before dawn.

I have booked time on telescopes in New Mexico and Nerpio, with the intention of taking 60 minutes of 120 second exposures from 2200 to 2300 (New Mexico) and 0600 to 0700 (Spain).

As always, there is a risk that local conditions - the weather - will intervene to spoil this enterprise. If you have any plans to image 2017 O1 overnight 18-19 October, please try and do so within these time intervals - UT 0400 to 0500 on 19 October. As long as the time stamp of one of your stacked frames overlaps one of mine, we can collaborate on a stereoscopic image. Do please get in touch through this post if you’re interested."

ALERT! URGENT! Comet 29P monitoring requested for Outburst capture (1-3 September)

Location of comet 29P as seen from the SSO scopes at  10:34 pm local time as it transits the meridian. The large rectangel is the field of view of T12, the small rectangle is the field fo view of T17. click to embiggen.

Comet 29P is known for it irregular outbursts. It has recently undergone a series of four outbursts in 13 days, reacing magnitude 13.5 (from magnitude 15.7!).  there was a major outburst on August 27, reacting magnitude 12 from magnitude 14.


Comet 29P recent out bursts (taken from the comet and asteroid FB group)

Richard Miles has called fro observations of 29P for possible new outbursts.

"Observers should be alert for a possible third outburst of 29P between now and 2017 September 03.0"


We now have strong evidence of two cryovolcanoes erupting twice on consecutive rotations (local days) of the nucleus during June 27 to August 27.

Looking at the entire dataset spanning 15 years (1 orbit of the Sun = 1 local year), there have been 130 outbursts detected and timed accurately. Of these there have been 14 instances of pairs of eruptions on consecutive rotations, and 10 instances when the same sources have erupted three times - each separated by one rotation. So that amounts to 45% of all outbursts happened on consecutive rotations from a small number (<10?) of cryovolcanic vents. It is this characteristic that makes it possible to predict some outbursts.

In addition, there have been 30 outbursts (23%) that have triggered a further outburst in their vicinity, i.e. within about 60 degrees longitude of each other.

That leaves only 25 events (19%) which are either isolated ones, or are repeat events from the same source but spaced in time by two or more local days on the nucleus. P.S. There are two other factors - one is that during the early years lots of outbursts were missed - second is that outbursts are missed very early on (and late on) in each apparition as the comet is close to solar conjunction."

Recent images of the comet from the Liverpool and Faulkes telescopes are here.

The comet is in Capricorn, between  iota Capricornii and Theta Capricorii, not far from 29 Cap. The comet is visible from both southern and northern scopes, although the Southern scopes have the best view. The comet transits at around 10:30 pm local time, however the waxing Moon will make observations increasingly difficult. On the 3rd the comet is just 6 degrees form the nearly full Moon. Narrow band observations will be required, R band observations may be best.

ALERT! Bright new cometC/2016 01

Comet C/2017 O1, discovered by the ASASSN supernova survey, as seen from the SSO scopes at astronomical twilight. The rectangle is the field of view of T12.

Comet C/2017 is a surprisingly bright comet which was recently discovered by the ASASSN supernova survey. It is currently around magnitude 9.8. It is unclear if the comet is in outburst, or has "switched on" as it crossed the frost line.

While the comet is already bright, observations are requested to follow its development. It is predicted to reach magnitude 7.5 in October.

Currently it is between Cetus and Eridanus, above Eta Eri. It is currently best seen in the SSO scopes, from about 230 am local time to astronomical twilight, from the Northern scopes the observations are limited to just before astronomical twilight. Currently it has no ineteresting encounters.

Over the month the comet evolves into a better viewing position, but by September it is more favourable for the northern scopes, and at maximum it is a northern object.
