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.

T27 SSO - First Light

On the heels of the recent launch of iTelescope T24 at the new iTelescope: Sierra Remote Observatory comes the newest member of the iTelescope family, The BCL iTelescope T27!

T27 is a record breaking, 0.7 meter Corrected Dall-Kirkham Astrograph by Planewave and will be the largest system we offer in the Southern Hemisphere, as well as the largest system on the iTelescope network.  The Planewave CDK 700 is a masterpiece of engineering, containing not only the largest mirror on the iTelescope Network, but also Dual Nasmyth Focus, giving it the ability for the system to operate two separate imaging tools on either arm of the Alt/Az Fork Mount.
This system will be initially outfitted with the FLI PL09000 CCD and a compliment of 12 Astrodon imaging filters with LRGB, 3nm Ha, SII and OIII, and photometric UVBRI.
For more details on the system, please check the T27 information page here.
T27 is dedicated to Dame Jocelyn Bell BurnellAnnie Jump Cannon and Henrietta Swan Leavitt (BCL). Hence, this instrument has been named “The BCL iTelescope”.  These three great women made important contributions to the science of Astronomy and were vital to our understanding of the Cosmos.
We are very excited for you to get your hands on this amazing system and look forward to all the amazing imaging and discoveries that it will bring!
If you would like to see some of the first images to come of T27 during it's Beta Test, check the images taken by iTelescope members below! 
This image of the Antennae Galaxy was captured by Noboru Yamamoto on T27 at iTelescope SSO.  It consists of 22 x 5 minutes of Hydrogen-alpha and 5 x 5 minutes of Red, Green and Blue, for a total of 185 minutes of exposure.  It was processed using Maxim, CCDStack, PixInsight, and Photoshop CS5.
This shot of Centaurus A (NGC 5128) was captured by Antonio Shiavone on T27 at iTelescope SSO.  It consists of 10 minutes of Luminance and 3 minutes of Red, Green, and Blue. (below)

ELV Light Panels now used at iTelescope.

Since the beginning of time, the chore of collecting accurate and consistent flat calibration data for over two dozen iTelescopes in three different time zones around the world had been my personal bane. Our usual 'Sky Flats' method is subject to many variables including star trails, scattered cloud, roof closures and very narrow windows of opportunity that make the collection of these rather important images very difficult. Indeed it could take weeks for us to collect enough useful samples of all the filters that our systems have installed. It was just nuts.

Well now we have installed electroluminescent light panel technology to make this task simple, with the highest quality possible for our members.

40" ELV in use on T27 SSOMultiple ELV panels ranging in size with Flip-Flats suitable for use on our wide field FSQs and refractors like T3 and to huge custom made, mobile panels up to 40" for our 27" systems have been installed in our observatories.

These panels can be controlled remotely and we are pleased to say the quality of calibration data from them is simply astounding. No more faint star trails, no more cloud ruining the frames. We can take as long as we like and collect dozens upon dozens of samples for each filter on every telescope and produce stunning flats, on demand at any time we choose!

This advanced electro luminescent panel technology provides a uniform source of illumination for the production of high quality flat field frames necessary for serious astroimaging and photometric work. With on-demand flat fields and uniformity errors of less than ± 2% are now possible.

We would like to thank Alnitak Astrosystems for their helpful and valuable advise in making my job for one far easier!


When Bigger is Better - T24 California Online

The final weeks of January 2014 was a busy time for iTelescope staff and the crew from Planewave USA, with the shipping and installation of the newest and largest iTelescope system to date.

T24 is the largest iTelescope system in the Northern Hemisphere. Its big, its beautiful. Situated under dark and clear skies deep in its Sierra mountains remote location in Northern California USA.

T24 is .61 meter (24") CDK reflecting telescope and the result of long and careful planning, manufacture and final configuration. Featuring the latest in imaging trains and software control systems T24 is sure to produce amazing images and groundbreaking deep science for its users on the iTelescope.Net network.

We know T24 will be a busy and productive platform in its role as a deep space imager for our remote astronomy community and we hope you too take the opportunity to give this star machine a try soon!
