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.

Hosting and Affiliates

iTelescope.Net offers a range of telescope hosting solutions to members with special projects, allowing you to host your own telescope at three of our four observatory locations. Conditions and approvals apply. Contact us for more information.(more)

Affiliate membership allows you to connect your own telescope to iTelescope.Net with reasonable rates of return. Limited availability exists and is subject to telescope network 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


UPDATE! Latest Elements for WT1190F (last opportunities tonight)

If you intend to try and image the putative space junk WT1190F, before it comes down tomorrow at 13 Nov 2015 around 06 UT, there are new ephemerides available from the JPL Horizons web interface (search on WT1190F)

and  the Minor Planet Ephemeris Services's Space Junk site (tick the WT1190F box)

In both cases you can specify the Mayhill Observatoy (H06) or SSO (Q26) or Astrocamp(I89) or URO (U69) as your observatory location.


ALERT! Observations of the Occultation of Mag 9.8 star by (29) Amphitrite requested

Location of the asteroid (29) Amphitrite and the target star TYC 1198-00160-1 As seen from Mayhill New Mexico 4 hours before the occultation. The rectangles are the fields of view of T5 and T30 (yes,T30's SSO but it is to late to redo the chart). Click to embiggen.

Observations are urgently requested by IOTA for the occulation of the 9.9 magnitude star TYC 1198-00160-1 by the magnitude 9.1 asteroid (29) Amphitrite.

The Asteroid occulation goes over Mayhill New Mexico, so the iTelescope scopes are well positioned to catch this. The occultation occurs between Nov 11 4:34 UT to 4:58 UT, from SkyMap the occultation is deepest at 4:48 UT at MayHill, which agrees pretty well with this table. 4:48 11 Nov UT is 9:48 pm 10 Nov at Mayhill local time.

Track of Asteroid (29) Amphitrite up to and after the occultation, the field of view is that of T5.Times are local Mayhill times. Click to embiggen.

The asteroid moves rather lazilly, so if you start observing 15 minutes before the prsumed occultation time to 15 minutes after you should catch the asteroid moving on even if the contact times are a few minutes out.

Peter Lake recomnds tracking on the star and doing multiple short (5-10 second) exposures.

ALERT! Observing Space Debris WT1190F

Location of WT1190F at 11pm 11 November local time Mayhill NM (12 Nov 06 UT). Click to embiggen.

WT1190F is a small object (possibly 1-2 metres in diameter) on a hyperbolic orbit around Earth. It is believed to be an artificial object, possibly a rocket body. It will impact Earth on November 13 around 06 UT.

This will be a challenging object to image with iTelescopes, as its magnitude hovers around 20. The best opportunity for iTelescope users is on 12 November UT when the magnitude falls below 19. When the object is at its brightest on the 13th, just before impact, it is invisible from SSO and Mayhill scopes.

From Mayhill WT1109F is visible from 11 Pm 11 November local time to around 4 am 12 November (6 UT-11 UT 12 nov). From SSO it is visible from 1 am 13 Nov to 4:22 am 13 Nov local time (14-17 UT 12 Nov).

Chart of the track of WT1190F as seen from Mayhill New Mexico or 6UT 12 Nov (11 pm 11 Nov local time). The rectangle is the field of view of T5. Click to embiggen.

WT1190F is not in the MPEC, but you can get a pseudo MPEC here at Project Pluto. As the orbit is still being refined, check in closer to the date for updated positions.

A WT1190F FAQ is here, along with impact zone predictions (just off Siri Lankar at the moment, but this will likely change as we know more).

AN ESA article on the object and the need for observations is here.

ALERT! Observations of comet 67P request to support a HST campaign

Chart of the location of comet 67P at astronomical twilight (4:57 pm local time) as seen from Mayhill NM. The comet is observable form Northern Hemisphere scopes only, and is within iTelescope range from 3:30 am (25 degrees above the horizon) unil astronomical twilight (43 degress above the horizon). Click to embiggen.

Observations of comet 67P are requested to support a HST Polarimetry Observations compaign scheduled for November 9, 10 and 11. People have been requested to be monitoring activity on those days.

All observations are welcome, but deep imaging, narrow band (including R, B  and V) imaging and dspectroscopy would be very valuable. Those who are not already members of the PACA_Rosetta group can email me for more deatils of how to submit images.
