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.

Support and Service

With remote astronomy observing plans can be interrupted from time to time, by clouds, wind gusts and even a rare equipment failure.

iTelescope.Net has you fully covered with our satisfaction guarantee; we will return your points if you are unsatisfied with your results. Help is just a click away. (more)

A dedicated team of professionals are working around the clock to keep the network operating. This includes local ground crews at each observatory, sophisticated monitoring systems and remote observatory administrators monitoring the quality of data coming off the network.

Our dedicated support website allows members to seek answers to frequently asked questions. Formal support can be requested by lodging a support ticket, which can be viewed, tracked and managed through to completion. Go to or simply email

Our contact details are also available. You can phone or Skype us if you want to speak to a person directly; you can also contact us via Skype instant message, email and fax.

How much does this cost?

Rates vary based on your membership plan and the phase of the moon. Rates start as low as 17 to 100+ points per imaging hour, which is billed per minute of imaging time used; typically one point equals $1. Make sure you are subscribed to our newsletter for special offers. Please visit our pricing page for more information on telescope operating rates. (more)

Each telescope has its imaging hourly rate displayed in real time in the launchpad before you login. At the end of each session you are also sent a detailed usage receipt which includes the costs, weather data, preview jpeg images and your observing session log file.

Membership Plans

We have a range of plans catering for everyone from the amateur to the professional astronomer. Each plan provides unrestricted access to each telescope and includes the plan’s dollar value in points, which is credited to your account each time the membership renews. (more)

Membership plans set the usage rates for each telescope on the network, expressed in points per operating hour. The entry level plans provide maximum flexibility on our single shot colour systems, and the heavy usage plans focus more on the large research grade systems. Memberships start from $19.95 and range to $999.95 per 28 day period.

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! Comet 67P and the Leo Triplet in Early April

Comet  67P Churyumov-Gerasimenko will be close to the Leo Triplet from around 4-8 April. The image shows the fields of view of T20/12/14 (large rectangle), T5/11 (medium rectangle) and T31 (square). All the others FOV's are too small for a reasonable composition. Click to embiggen.

In early April comet 67P Churyumov-Gerasimenko will be close to the famous Leo Triplet.

This will be a challenging  image to take as comet 67P will be around magnitude 16 at this time, but it is quite historic so worth the effort. The comet is moving slowly so that deep tracking on the comet will not smear the galaxies too much.

A tip of the hat to Stuart Atkinson for alerting me to this.

ALERT! Comet 252P brightens quickly! (in outburst?)

Chart of the path of comet 252P/LINEAR as seen from SSO. The large rectangle is the field of view of T12. Click to embiggen.

Comet P252/ LINEAR has been reported to be anomalously bright, some reports put it well above its theoretical maximum of magnitude 11. A recent report from Michael Mattiazzo has it at magnitude 8.2, and other reports are of similar magnitude. The comet appears to have a diameter of 23-24 arc seconds.

Observations are requested to follow the evolution of this outburst. Currently it is brightening at around 1 magnitude per day!


The comet is visible from SSO scopes from nautical twilight to around 4 am.

As well on the 16th and 17th (and part of the 18th) comet 252P will be in T12 range of the Large Magellanic Cloud. on the 17th it is one degree from the 10th magnitude globular cluster NGC 2210. This should make for an interesting shot.

ALERT! Comets P252 and P/2016 BA14 come close to Earth


Chart of the path of comet 252P though the southern skies as seen from SSO. The time is 24:15 am (13:15 UT). The rectangle is the field of view of T12. Click too embiggen.

Comets P252/ LINEAR and P/2016 BA14 (PanSTARRS) come very close to earth (around 10 Earth Moon distances away) on March 21 13:15 UT (March 22 00:15 AEDST at SSO) and March 22 15:31 UT (daytime at Mayhill).

While they are currently close in  Columba, and make their closest approaches at similar times, they are unrelated comets. P252 passes through Pictor, Octanis and Scorpius and has its closest approach in Apis.

P/2016 BA14 passes through Canis Major, Cancer and is at closest approach in Leo.

Chart of the path of comet P/2016 BA14 though the northern skies as seen from Mayhill new Mexico. The time is 00:31 am (7:31 UT). The rectangle is the field of view of T14/T20. Unfortunately closest approach is in daylight for Mayhill, and the comet is too low for observation from SSO at closest approach, although visible earlier.

At closest approach both comets will be moving rather fast, quite possibly at the limit of tracking of the scopes. 252P will be travelling at 24.55"/minute and P/20116 BA14 will be travelling at 48.68"/minute.

The comets will be around magnitude 11 and magnitude 12, and extended fuzzy objects, so drift tracking will be less satisfactory than with NEO's

There is a  small but significant parallax effect. While it is not a big problem with the wide field scopes for the narrow field scopes, unless your planetarium program is able to cope with close parallax (most can't), you may need to work from topocentric coordinates.

For topocentric ephemerides go to

Use the oobservatory code for your observatory eg  MPC Siding Spring Code Q62. Mayhill Code H06.

ALERT! Supernova in Centaurus A, Observations requested

Location of the supernova SN 2016adj in the galaxy Centaurus A as seen from the SSO scopes, the rectangle is the field of view of T9. Click to embiggen.

A " bright"supernova has been discovered by the Backyard Observatory Supernova Search (BOSS) in the iconic southern galaxy Centaurus A (NGC 5128).

Initially reported as V magnitude 14, subsequent measurements give a V mag of 15.7. It is probably a Type Ib supernova a week past maximum brightness, but is in a dusty part of the galaxy with significant reddening so it might be some other sort.

Observations are required to follow the evolution of this supernova.

Unfortunately it is very close to a bright star in the dust lane, so will be hard to separate out.

RA. 13:25:24.11 Dec. -43:00:57.50(J2000)
