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

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.

Narrowband Imaging - What's it all About?

An iTelescope Article by Dr. John Ebersole

If you enjoy photographing nebulae, I hope you will try narrowband imaging.  The results are worth the small amount of extra effort.

For many of us, our first view of a narrowband image was the 1995 release of the “Pillars of Creation” from the Hubble Space Telescope (HST) (Fig. 1).   It was significantly different from the typical views of red emission nebulae, when RGB filters are used.  Not only were the colors different, but there was remarkable color contrast and a 3-D effect unusual for traditional color images.  This image was taken with emission line filters for ionized Hydrogen alpha (Ha), Sulfur II (SII), and Oxygen III (OIII).  These three grayscale images were combined into an RGB color image using the now classic, wavelength-ordered (longest to shortest), HST palette, wherein SII is portrayed in red, Ha in green, and OIII in blue.

Reservation System Update Live!

We have listened to the positive feedback and finished testing the changes to the Reservation Page. Members that responded to the newsletter were overwhelming positive about these changes, so we are bringing them online now. For information on these changes, Please check the link below.


Introducing the Latest iTelescope! T33 - SSO

We are very happy to announce the first new system to the network in over a year, iTelescope T33, which will be brought online soon at our Siding Spring Observatory site.

This system is the first of many new systems and services that are being brought to the network with funds raised directly from our latest Billing System Update.

We want to thank all members that chose to convert to the new system - we would not be able to bring this system to the network without your help!

Instrument Package:

Telescope T33's OTA is a fast 16" F/3.5 Astro Systeme Austria (ASA) Astrograph mounted on a Paramount ME. The OTA is coupled with a large format main imaging camera and guided with a Starlight Xpress Lodestar using a custom made Off-Axis adapter. This will be the first Off-Axis guided system on the network!

Telescope Optics:

The main imaging camera on Telescope T33 is a 16 megapixel Apogee Aspen CG16070 Class 1 CCD paired withan Apogee FW50-9R 9 Position Filter Wheel.  This configuration delivers an 87 x 58 arcmin FoV at an image scale of 1.07 arcsec/pixel.
Its filter wheel is filled with a fantastic compliment of seven Premium Astrodon 50mm Round Filters Imaging Filters:
  • Astrodon Series I Luminance, Red, Green, and Blue (LRGB) 
  • Astrodon 5nm Hydrogen-Alpha, 5nm Oxygen-III, 5nm Sulfur-II (Narrowband)
To give an example of what this system is capable of, below is an image taken on the system from our Siding Spring Observatory site. T33 will excel in any mission that requires a wide field and fast imaging of faint extended objects such as clusters, nebula and comets.

The T33 system will go online before the end of May.
We cannot wait to see the fantastic images that iTelescope Members take on this Pure Imaging system!
