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.

"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

ALERT! Comet 174P in Outburst

Location of comet/asteroid 174P/Echeclus as seen from Mayhill Newmexico around 3:00 am local time. The large rectangle is the FOV of T14/20, the small that of T05. Click to embiggen.

174P/Echeclus has been reported to be in a rare outburst. Originally described as a Centaur object, it has since shown cometary features, with outbursts in 2006 (when it shed a fragment) and 2011.

The comet has jumped from magnitude 17.9 to 15.2. Faint to be sure, but reachable with several of the iTelescopes.

Observations are required to follow the progress of this outburst.

The comet is in Pisces, near Uranus. The comet is visible in iTelescopes in both the northern and southern hemispheres (although north is best) from around 11 pm local time, transiting around 3 am and still accessible until astronomical twilight.

ALERT! Comet 29P in Outburst

Location of comet 29P as seen from the SSO scopes at astronomical twilight. The large rectangle is the field of veiw of T12 and the small that of T9. click to embiggen.

Comet 29P is known for it irregular outbursts. On July 27.75 UT the comet underwent an outburst going from magnitude 16 to magnitude 13.1. AT the time of writing the comet is still around magnitude 13.5.

Observations are required to follow the progress of this outburst.

The comet is in Sagittarius, near the handle of the teapot, in a somewhat crowded field and may be difficult to follow. The comet is visible for around 5 hours after astronomical twilight from the northern hemisphere scopes and most of the night from the southern heisphere SSO scopes.

July Highlights: Comets C/2013 X1, 252P, C/2014 S2, 9P/Temple 1

New Moon is 4 July,  First Quarter 12 July,  Full Moon 20 July and Last Quarter Moon 25 July.

Comet C/2013 X1 (PANSTARRS) passes close to some nice objects in late June early July. Detailed charts and ephemeris are here. In late July the comet has no really interesting encounters, but is withing T12 distance of the faint galaxies IC4464 (M 1.8) o the 22nd and IC 4458 (23rd). On the 30th the comet is 17' from mag 12 galaxy IC 4430

The path of Comet 252P in Ophiuchus. The large rectangle is the field of view of T14/20, the small that of T5. Click to embiggen.

Comet 252P has faded substantially, and is now moving slowly. Current magnitudes are uncertain, the most recent reports are from June 5 and 6, suggesting it is either 12.6 or 11.7. It will certainly fade substantially over the course of July, possibly below magnitude 13.

The comet remains in Ophiuchus this month, passing two bright globular clusters, M12 and M10. On 16 July the comet passes within 2 degrees of M10, a mag 6.1 globular cluster. On 31 July the comet passes 2 degrees 14' from M12, a mag 6.6 globular cluster. The large disparity in magnitudes will make imaging difficult.

The waxing Moon is within 30 degrees of the comet from 13-17 July.

The comet is visible after astronomical twilight from SSO and the northern hemisphere scopes until the early morning, with transit mid evening. The table below shows rise set and transit times from Mayhill New Mexico, and the comets altitude at 21:00. Transit and altitude at SSO is similar.

Comet C/2014 S2 PanSTARRS is dimming and the last reported magnitude was arround 12.

Visible from both northern and SSO scopes at the moment, it is only visible fo about an hour after astronomical twilight before it is too low for scope travel.

The comet passes within T14/20 distance of a number of faint galaxies, but their size and faintness, along with the comets faintness may make imaging  suboptimal.

The path of Comet 9P in Virgo. The large rectangle is the field of view of T12, the small that of T9. Click to embiggen.

Comet 9P/Temple 1 is in a good position for observation in Virgo, and is visible from both northern and southern scopes during the early evening, although the SSO scopes are favoured with around a 2 and a half hour window before the comet is too low for the scopes travel.

However, the comet is is substantially dimmer than ephemeris predictions of 10.9, and the most recent estimate of 11.6 may represent a transient outburst, and the comet may be rather disappointing this year.

From the 4th to 6th the comet is within 13' of two faint magnitude 11 galaxies, on the 9th it is 33' from the magnitude 9.9 galaxy NGC 4753
