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 20 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.

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.

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.

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

Dr Ian Musgrave  - iTelescope Science Advisor

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! 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)


ALERT! Comet C/2013 US10 Amongst the Galaxies (Jan 13-17)

UPDATE: T20 and T14 are at 90 degrees not 0 degrees as illustrated. This will alter significantly how you make mosaics.

Chart of comet C/2013 US10 between the 14th to 17th of January, 2016 as seen from Mayhill New Mexico at astronomical twilight in the morning. The rectangles are the field of view of T20, T14 and T3 have a similar FOV. Click to embiggen. 

If you have been following comet C/2013 US10, you will have been noticing, aside from the gorgeous double tail, that many fields are dotted with tiny galaxies.

This will change on the 13th and 14th and 16th and 17th (UTC) when the comet is relatively near to the Whirlpool galaxy (mag 8; 13th and 14th) and M101 (mag 7, 16th and 17th). The comet should be high enough for imaging from 1 am local time to astronomical twilight (around 5:15 am local time)

For most of these shots you will need to make a mosaic to capture the galaxy and the comet at their best. Here is my guide to making mosaics using the iTelescopes (in this particular one I was looking at the comets tail, but the same applies to any form of mosaic).

After this the comet traverses several fields of tiny galaxies, and on the 29th it is in mosaic distance of NGC 4236-1 (magnitude 10, 21.9'x7.2')


ALERT! Observations Requested for Outburst of Comet C/2013 X1 

The location of comet P/2013 X1 (PANSTARRS) as seen from Mayhill New Mexico at astronomical twilight in the evening, the comet is in the great square of Pegasus. Click to embiggen.

Comet P/2013 X1 (PANSTARRS) is reported to be in outburst at magnitude 8.5 or brighter and observations are required to follow its evolution.

The comet can only be observed in the Northern Hemisphere scopes, where the comet is at a suitable height from astronomical twilight in the evening to around 10 pm local time.

The comet is located in the great square of Pegasus, in a triangle bounded by gamma, Chi and Phi Pegasi.

ALERT! Bright Supernova near Beta Virginis in PGC 037392, Observations requested

Chart of the northern sky as seen from SSO at astronomical twilight in the morning 04:23 am local daylight saving time. The location of PGC 037392 and the supernova is indicated with the black box (click to embiggen).

A bright supernova (magnitude 14.7 as of last observation, and likely to get brighter) has been detected in the dwarf galaxy PGC 037392 ( see ATEL # 8502 and further follow-up here). Observations are requested for follow-up.

The type II supernova is around 6 degrees from Jupiter and one degree from Beta Viriginis, thus fairly easy to find.

It is visible in both the SSO scopes (around 2:30 local time) and the Northern Hemisphere scopes from around 1:30 am local time. to astronomical twilight.

Chart of supernova location as seen from the SSO, the large rectangle is the field of view of T5, the small that of T9, the supernova is indicated by the circle (click to embiggen).

The location of the supernova is
R.A. = 11h55m04s.25, Decl. = +01°43'06".8
