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

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.

Additional points can be purchased at any time to supplement your account balance.

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 C/2015 F4 Jacques amongst the Galaxies 

Comet C/2015 F4 Jacques near the galaxies PGC 64456 and PGC 64450 as seen from the Siding Spring Observatory at 2:00 am local time on April 18. The rectangle is the field of view of T9. Click to embiggen. 

Denis Denisenko on comets-ml has alerted us to a challenging but interesting imaging opportunity.

Comet C/2015 F4 Jacques comes within 4' of galaxy IC 4991 (PGC 64450 mag ) and even closer to the smaller and fainter PGC 64456 (mag 14.3) on April 17th at about 16h UT. This translates to 2:00 am on the 18th at the SSO scopes.

The comet is in Saggitarius, and is best imaged from the SSO scopes, the observational window runs from around 1 am on the 18th to astronomical twilight on the 18th at just after 5:00 am.

Currently magnitude 15.7, you will need fairly long exposures to bring out the comet, so not smearing the galaxies will prove a challenge if you are tracking on the comet. There are other galaxies so a bit of composition off the comet may be worthwhile.

The MPC one line ephemeris is:

    CK15F040  2015 08 09.7260  1.679893  1.000000   34.4654  286.4132   48.3598  20150627  11.0  4.0      C/2015 F4 (Jacques)


Citizen Science Project - Watching for Outbursts of comet 29P

Comet 29P as seen from the SSO scopes at midnight in April. Click to embiggen.

Richard Miles has made a prediction at the recent British Astronomical Association meeting the comet 29P/Schwassmann-Wachmann will have an outburst on 23 April +/- 3 days.

A request for observations has been made, for observations of 29P for the last 10 days of April. Catching an outburst would be very important for our understanding of these events in a comets life.

So, if you can, try and make observations of the comet in this time frame. On March 16 the comet was magnitude 16, and should be up to magnitude 15.5 now, an outburst of 1-2 magnitudes should be captureable with the iTelescope scopes.

The MPC one line ephemeris is:

0029P         2019 04 04.8131  5.761153  0.041659   49.8027  312.4086    9.3771  20150627   4.0  4.0    29P/Schwassmann-Wachmann


ALERT! Comet C/2015 G2 MASTER (Formerly M503ujx) Close to the Helix Nebula April 19-22.

Comet C/2015 G2 MASTER (formerly M503ujx) as seen from the SSO scopes at astronomical twilight in the morning, the large rectangle is the field of view of T12, the small that of T9. Also nearby are 88P/Howell and C/2013 US10 Catalina. Click to embiggen.

The presumed comet M503ujx has been confirmed as a comet and is now C/2015 G2 MASTER (potential comet XMAAS is now C/2015 F5 (SWAN-XINGMING)). It is visible high in the eastern morning skies from the SSO scopes, being around 39 degrees above the horizon at astronomical twilight, and remains high for most of April, disappearing in mid May to reappear in the evening sky.

Between the 19th and 22nd of April the comet is within T12 distance of the Helix nebula. On the 19th it is 1 degree away from the Helix Nebula, on the 20th it will be 33' from the nebula and on the the 21st it will be 43' away.

The ephemeris lists the comet as being magnitude 11 at this time. But currently it is around magnitude 9, about 2.5 magnitudes above the ephemeris predictions. It may possibly reach magnitude 6 in mid-May evening skies, passing through Eridanus and Lepus.

The Helix Nebula is magnitude 7.9, a stack of 10-15 1 -2 minute exposures may bring them both out nicely (Rolando Ligustri may advise differently).

MPC one line ephemeris:
    CK15G020  2015 05 23.8022  0.779770  1.000000  257.4779  110.0566  147.5512  20150627  11.0  4.0      C/2015 G2 (MASTER)
