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 13 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 half metre (20”) 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.

Astrophotography

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.

How?

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 http://support.itelescope.net or simply email support@itelescope.net.

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 any one of our three 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.

iTelescope - T7 - Deep Field

<->

Location

AstroCamp Observatory. Nerpio, Spain - MPC Code - I89

(TEL T7 0.43-m f/6.8 astrograph + CCD)

UTC +1:00 Madrid Daylight Savings Time is Observed

Minimum Target Elevation: Approx 35 - 45 Degrees

North: 38° 09’ - West: 002° 19’

Operational Notes

Deep Field Telescope. Hybrid Science/Imaging Platorm. Typically used for RVB / Narrowband Imaging, but also carries Photometric V and I filters. FITS and TIF file formats. Sub-exposure times should be kept to 60, 120, 180, 300, 600, 900  seconds for optimal results. Binx1 - Binx2.

T7 is a 17" Hybrid platform utilising a large format STL11000M CCD. This is an ABG camera so it lends itself to long exposures on a wide variety of targets. T7 is populated with photometric RVB filters so it stands well in the science stakes as well as a set of narrowband units for amazing Hubble palette imaging. Care however should be taken when using T7 for photometry as its CCD is of the ABG variety. So users should make sure they don't saturate the image as result may not be linear.
