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.

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.

Pushing Back the Limits with T17 - Josep Drudis

I am 62 years old, come from a Catalan-Spanish family, hold a MSc in Chemistry, a PhD in Chemistry (both at the Universitat Autonoma de Barcelona, Spain) and a MSc in Astronomy (Swinburne University of Technology). After a 20 year long career as Managing Director in several companies, I retired three years ago, with the intention of devoting my free time to my two passions: my family and astrophotography.
~
I currently teach astrophotography at the Agrupación Astronómica de Sabadell (AAS with 1000 members). Some 18 months ago, I developed a project to find a method to calculate the minimum exposure time to get a "decent" image. This project was concluded thanks to the invaluable contribution of some co-members at the AAS with a great deal of images and their parameters.
This method allows the calculation of the exposure time of any object, point-like or "deep-sky objects", as well a using the same equations to determine the ISO sensitivity of a CCD camera, using known exposure times of images of stars with known magnitudes. The method uses as variables the telescope's aperture, its focal ratio, the sensitivity of the camera, the tabulated surface brightness or the magnitude of the object to be imaged as well as its dimensions (in arc-minutes). It provides the exposure time in seconds for each subframe.
~
Astronomy has been one of my passions since I was 18. I soon got binoculars and bought my first scope when I was 30. Two years after that I started taking pictures with it. I prefer to image deep-sky objects.
Imaging quasars has been one of my challenging goals within astrophotography (my first picture of 3C273 was taken in March 1995 on TMax400 film). Recently, I started a personal project to try to get images of several faint, and far away, quasars. As long as my equipment is limited (11-inch SCT with an ISO 5500 camera, 6.3 MPx), I decided to mix in iTelescope's scopes. Imaging faint point-like objects requires very long exposure times or moderately long ones if imaging with large aperture telescopes and CCD cameras with high ISO sensitivity. Being my telescope and camera both moderate in these parameters,  iTelescope.Net came immediately to mind. The best combination of aperture and sensitivity is given by T17 (43cm aperture and an extraordinary IR-sensitive camera with an ISO sensitivity of 35000).
In this project (the full lecture on it was presented in May 2014) several quasars have been imaged at a redshift ranging from 0.158 (3C273) and 5.18 (J140025.54-12957.02).
At this point, knowing that Christian Sasse's world record was a very faint quasar with a z=6.41, I tried to get an image of J112001.48+064124.30, having a z=7.08 (other high-z-quasars have a high north declination and therefore out of T17's sight). Its light is so much redshifted, that its spectrum starts to have some intensity beyond 920nm. The attempt failed and then I redirected the goal to a faint galaxy showing a redshift of 6.7014. According to its surface brightness (visible magnitude and size roughly calculated from the image from SDSS DR9) and the above mentioned calculation method, the exposure time had to be 310 seconds, if imaging with T17. 
The galaxy is indeed visible in all (15x300seconds) subframes I took in two different nights.
The recorded high z galaxy is not as dim as the previous record holder quasar (it has a tabulated g-Mag: 18.40, low for an extended object), but its light has been travelling for nearly 13 bn years (it left when the Universe was only about 820 Million years old). This galaxy lies well within the reionization period (it ended at about z= 6.1).

Josep is currently working in close collaboration with Dr.Christian Sasse and they hope together to design imaging missions that will push the outer limits of 'amateur' astronomy back even further!
