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


June Highlights, M51 and C/2009 P1

Images of M51 and its supernova taken of 4 June, left image taken with GRAS-05 1x120 second exposure with a clear filter, right image taken with GRAS-07 1x300 second luminance exposure (click to embiggen).

The stand-out target for June is of course M51. The supernova detected in it is of course a key reason for this. As of writing the supernova is still bright seven days out from the original detection, and there is a need for long term follow-up of this supernova (and I repeat my call for images of M51 in the critical period when it was first detected, and Rochester Astronomy is also looking for submissions).

However, M51 – the whirlpool galaxy, is a classic and beautiful target in its own right. Colour images of this galaxy are particularly nice.

Chart showing location of C/2009 P1 Garrad during June. Rectangles are the field of view of GRAS-05 (click to embiggen).

While there are an abundance of comets about, most are below magnitude 13. 2011 C1 McNaught is relatively bright, but does not rise above 20 degrees above the horizon before astronomical twilight. 2009 P1 Garrad is around magnitude 10, and is above 20 degrees at astronomical twilight.

On the border between Pisces and Aquarius, it is within GRAS-05 range of the 13th magnitude galaxyNGC 7428 on July 15. Unfortunately, the nearly full Moon is still up (although close to the western horizon).

On the 23rd and 24th it is within GRAS-05 range of a group of small galaxies the brightest being magnitude 13 NGC 7396. Howevere at this time the last quarter Moon is high in the sky.

You can download the MPEC elements or use the one-line elements below.

A cornucopia of comets!

 While we are focused on M51, a whole slew of new comets have been found. Rob McNaught heads further into the record books with the discovery of his 62nd comet C/2011 L3 (McNaught), as well as C/2011 L1 (McNaught) and C/2011 L2 (McNaught). L3 will brighten to magnitude 15.5 and pass through some interesting territory. The others will dim.

Also recently discovered are C/2011 K1 (Schwartz-Holvorcem) and P/2011 JB15 (Spacewatch-Boattini). Sadly the latter two are quite dim, less than magnitude 19, and will only get dimmer. If you are in the mood to image these comets, then you can get their elements from the MPEC, or use the one line elements below.

Crowdsourcing the M51 Supernova

As I mentioned in the M51 Supernova alert, I'd like to try crowd sourcing the supernova. I'd like to invite any iTelescope users who have taken images of M51 between May 28 (when no supernova was present) and June 2 and beyond, to submit them to us so we can do public astrometry on them and follow the supernova out burst (and hopefully catch it at its earliest stages).

Send your images to us via the iTelescope user image upload

We'll keep you posted on the progress of the project.

As ell, I'd like to encourage everyone with images of M51 from May 28 on to submit them to the Flikr group astrometry, which automatically performs astrometry on the images,

Cheers! Ian


ALERT! Supernova in M51

French amateurs have reported what appears to be a supernova in M51 (2 June 2011 at 00:52 UTC). Details (in French) and images here.

UPDATE: Type II supernova confirmed. details here.

Image from T-07 by Pete Poulos  showing the supenova. Could any GRAS users who have before and after pictures of M51 spanning May28 to now submit them so we can do a crowdsourced follow-up of the supernova
