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.

All, welcome to my little corner of the iTelescope.net Website, where I will be posting a little astro action and activities from my AARTScope Blog as well. Due to my association with iTelescope and through my blog, the Hubble Space telescope and ESO now follow me on twitter.

I regularly chase asteroids and work with Variable star observers so I'll keep you up to date on my activities.

Astronomy is a pursuit where everyone is so helpful and eager to share their knowledge, with the internet and a growing population of iTelescope.net users, its a great scene to be a part of. 

My AARTScope blog is where I do most of my writing and occasionally host the Carnival of Space. AARTScope's mission is to "help create the sense of anticipation and discovery that keeps scientists asking questions".

AARTScope is quite deliberately a blend of Art and Science which highlights the full capabilities of T-011, as its great for the best of astrophotography and has already done some stellar science (if you pardon the pun).

Some of my most popular articles have been the Hyabusa Re-entry live blogging session where over 300 visitors from Asia and around the world joined the live blogging session. Recently I also did a great article for the ESO on Paranal and the visit of the world's first electric supercar.

I have also done a couple of interviews on Astronomy.FM including one on Photometry as a cloud service. Yep you read that correctly, iTelescope.net is certainly on the cutting edge.

2005 YU55 passes inside 1 lunar-distance - Nov 8th 2011

As you have no doubt heard, Asteroid 2005 YU55 will pass inside the orbit of the moon at about 85% of the distance to the moon.

Will it go close to the Moon? Not really, as it will cross earth's orbit at a distance almost as far above the orbital plane as it is distant from us along the plane.

Still, that is very close in Astronomical terms and no (known) object of this size will pass this close again for another 17 years - 2001 WN5, which is a whopper at about 1 Klm wide, will come through at bout 0.7 LD (Lunar Distance) in June 2028. Then in 2029, Apophis makes its really close pass on April 13th, which I really hope isn't a Friday, but the path is well known with very low uncertainty and it too will pass safely by. So this is a very exciting event and will receive lots of coverage, with great opportunities to grab great photos and create videos.

On the evening of Nov 8, 2005 YU55 will approach from the daylight and will whiz across into the night sky travelling at a cracking pace up to 540 Arc secs per minute. So on the evening of the 8th it presents a challenging target. If you have a field of view of 4008 x 2675 Pixels at say 1 arc sec per pixel, you'll need about 4 "spot on" 20-30 sec frames to grab it......or you can wait for a few days until it slows down.

So some coaching might be in order here.

There are two ways to attack this:

1)  Goto the position it will be "at an EXACT time" and camp on that position, and wait for it to fly through your photos.

2)  Use the one line element to track on the actual asteroid as per the "Track Comet/NEO" approach on GRAS telescope interface.

The one line element will look like this:

K05Y55U 21.9   0.15 K118R 348.84963  268.77407   39.31601    0.51346  0.4289481  0.80685648   1.1427166  0 MPO196642   767   2 2005-2010 0.44 M-v 3Eh MPC        0000         2005 YU55           20100421

NOTE: DO NOT copy the above as even though the Asteroid is not visible until the 8th, the Arecibo and Goldstone Radar Radio Telescopes are already tracking it and have updated the orbit elements already. ALSO the above code is specific to H06 (New Mexico) observatory code, so it is only usable at that location. You should go to the MPC and the latest elements for your session. Note: some astronomy planetarium programs may not give you the best position, as unless they have the latest elements for the correct Epoch then you may run into some problems, this is less likely to be a problem, due to the high certainty of the orbit. [This was a problem for 2011 MD as it was inside the Hillsphere and was changing direction on an hourly basis]. As a rule I always get the latest data from the MPC.

If you go to the MPC

http://www.minorplanetcenter.org/iau/MPEph/MPEph.html

Click on "Minor planet epheremis" enter object "2005 YU55", click on "hourly" or "minutes" (not daily), and the enter observatory code of the telescope (NMS H06, Nerpio I89...  etc or your own LAT/Long if you are doing this from your own scope at a different location).

If you want the exact co-ordinates hit enter, if you want the one line element then also select "MPC one line element" at the bottom.

You will have all you need.

So for Step 1) [Above] you enter the exact co-ordinates into the  "Plan Generator" on the GRAS telescope interface, select your image duration etc. Save your plan. Then set up a "Launch a plan" reservation with a target of your co-ordinates and set up the start time to be 15 minutes before your target position, to allow the telescope to get through its focus run and shoot a couple of frames before it arrives. Note: the reservation tool works in local time whereas your Ephemeris generated by MPC will be in UTC. So you will need to account for this. If you get it right the Asteroid should fly on through your image right on queue. (Later in the week after the 10th this won't be quite so critical and you can revert to hourly positions, as it will then only be going <10 arc sec per minute) which means it will take some hours to cross your image field of view.

In the MPC Ephemeris printout the most cool feature is that it will tell you how far above the horizon the Asteroid is for your location......so you should target something reasonable Target ALT= >+35 degrees. It the ALT is minus its below the horizion, the the Sun ALT is + its day time ;-).

For Step 2) [Above] Once you have the One line element, making sure the Asteroid is above the horizon, on the GRAS Observation Plan, select "NEO/Comet" and you can paste the One line element straight into the Target box, select any other parameters like platesolving, etc. Once you start the run the Telscope will slew to the position and track the asteroid. (in this instance the asteroid will appear as a dot and the background stars will trail)

From Nov 8-9 it will be mag 11-13 so a 30 sec image will be fine, after the 10th about mag 14+ you would best go with a 60-120 sec image. (you might want to go a little longer on the smaller scopes)

If you are competent in Photometry you can participate in an observing campaign (Brian Warner is leading it) but that doesn't start till after the 10th when 2005 YU55 slows to a reasonable pace. (relatively.......it just keeps going but relative to earth its moving across the sky slower)

The MPC (Minor Planet Center) also has an observation guide page on it

http://www.minorplanet.info/ObsGuides/YU55/

This is a great opportunity, and you can amaze your friends with your telescope skills, this is a very exciting event and everyone will be talking about it by Friday/Saturday.

Enjoy, I hope you find the above helpful.
