Back to the Beginning of Time

The four most distant galaxies ever imaged with an amateur telescope

Amateur astronomers and iTelescope members Josep Drudis and Christian Sasse have just imaged the four most distant objects ever seen with an amateur sized, off the shelf telescope. These four galaxies emitted light when the universe was only 760 million years old, or 6% of its present age - it was very very long ago, in fact they are looking back over 13 billion years!

Why did they do it? It was a cool idea - previous records were obtained on distant quasars - very bright compact galaxies. Redshift is a measure of distance since the further away an object is, the more it is redshifted.

This also means that the light emitted from a very distant galaxy is no longer visible to most cameras, its light has simply passed too far into the 'dark' red portion of the spectrum and is thus difficult to detect.

Drudis and Sasse wanted to go beyond a redshift of 7, and it was difficult to find suitable objects. They searched for and found four very distant galaxies and used T17 with its special camera and 400mm (17 inch) CDK optics located under ideal clear and cool skies at iTelescope's remote observatory at Siding Spring Observatory in Australia for this purpose. This CCD telescope combination could 'see' more into the red bandwidth of light. 

T17 is a powerful amateur science platform. It is normally used for Science Missions, Deep Photometry, Narrowband and 'Extended Red' light IR imaging missions.
Clearly it was a challenging task for all involved, including dedicated ground staff. It takes many hours of careful aligning, testing and imaging required until the objects finally appeared. This result was somewhat unexpected and a pleasant surprise for all involved.
Below are images of the four galaxies. Drudis and Sasse are keen to continue and push the envelope of amateur imaging even further.


Comet Siding Spring & Mars - iTelescope at your Service

On the night of January 3rd 2013 Rob McNaught, as he had done for thousands of nights before, was methodically searching the Australian sky above the Siding Spring Observatory (SSO). The venerable Uppsala Southern Schmidt Telescope was scanning for undiscovered and potentially deadly pieces of rock and ice debris remaining from the formation of our solar system eons ago.

Rob's business card could realistically have included the description 'Guardian of the Earth'. It was his job to find and predict the paths of comets and asteroids potentially hazardous to all of us here on our little world.

H.Sato - T30That night he was carefully scanning the small constellation Lepus and he found something that appeared quite 'normal' to Rob. A faint (magnitude 18.5) and very distant object (1.08x109 Km). It was only a feeble smudge a few pixels across in his images, but it was a positive identification of yet another dark body moving towards the inner solar system in an orbital swing around our Sun.

Thus did Comet C/2013 A1 (Siding Spring) first come to the world's attention. iTelescope member H.Sato was involved in collecting some very early astrometric data using the T30 iTelescope also based at Siding Spring. His own confirmation data amongst the initial observations made by others suggested that the path of this particular little comet was extraordinary indeed. As C/2103 A1 swept towards the Sun it would pass ridiculously close to the planet Mars during October of 2014. So it justifiably garnered major attention from the astronomical community.

R.Ligustri - T32 SSOThe iTelescopes based at Siding Spring were in an ideal position to play a major role in the study and measurement of the comet over the next year and a half. Our members watched it closely with hundreds of images taken during its long million year journey towards Mars. It was dim and hardly spectacular to begin with, but this little comet was unique and important to planetary scientists the world over. It was from the distant Oort Cloud and this was its first visit to the Sun. A pristine piece of the stuff from which our Solar system including Earth was formed.

So as October 2014 finally arrived many observers from around the world logged into the iTelescope SSO observatory via the internet and began their imaging missions. Some were experienced and others new to the art of astrophotography. The target was low to the west and only a narrow window of opportunity was open to gather as much quality data as possible. The images on this page are only a small sample of the images taken by our membership. Some took hundreds of images over many months as the comet approached.

Here we feature some of the finest images of the Comet's encounter with Mars. It should be pointed out that the huge contrast in brightness between the comet and the planet Mars made this target especially difficult to capture as most certainly the planet would be overexposed during the session. Many of these images were also picked up and distributed by several major TV networks and newspapers, NASA, ESA, National Geographic and Nature magazines. Two of our master imagers had their works selected by the NASA-APOD website. We thank those that contributed their work for this showcase...and thanks for the hard work Rob.




Ribbons, Dedications and Celebrations at iTelescope Siding Spring

During this year's amazing SSO 2014 Starfest & Open Day beginning 3rd of October, iTelescope.Net took the opportunity to invite its friends, contributors and many members to the mountain for two important ceremonies within our flagship observatory.

It was a glorious and sunny Australian weekend that included other important birthdays too. The Siding Spring Observatory complex itself had its 50th anniversary, the 4m AAT telescope celebrated the 40 years since its first light and the ANU 2.3m telescope has now been operating for 30 productive years as well.

We at iTelescope also had plenty to celebrate and dedicate on the weekend. A wonderful turnout of guests gathered within the largest roll off roof observatory in the world for two important events. Fine champagne and food was enjoyed as we took the opportunity to officially open the iTelescope SSO facility and also dedicate the largest iTelescope system to three important female astronomers.  Dame Jocelyn Bell BurnellAnnie Jump Cannon and Henrietta Swan Leavitt. Hence, this new instrument has been named 'The BCL T27 Telescope'.

iTelescope kicked the weekend off with a great LIVE webcast featuring iTelescope's own Peter Lake with special guests Dr Pamela Gay, Dr Amanda Bauer and affiliate Neil Shaw. Its well worth watching as our guests discuss the BCL telescope and the role SSO plays in astronomy today.

Friday also saw the iTelescope Observatory quickly fill with guests from far and wide for its two dedications. The SSO iTelescope facility, as mentioned by Managing Director Brad Moore in his welcome address, was due to be officially opened in January 2013, but the tragic and horrible fire storm that swept through the surrounding national park and threatened the observatory itself put those plans on hold. It was thought best to postpone the opening until the whole SSO site was celebrating its 50th anniversary open day. Mr Moore thanked all those involved with the financing, construction and operation of the facility as well as our many friends on the mountain from the Australian National University's Facilities & Services division, its world renown Research School of Astronomy and Astrophysics and also the incredible Australian Astronomical Observatory all of which have been so generous in their support. Brad also thanked our iTelescope membership, that the observatory was built for them and indeed would not exist without them.

Neil Shaw, iTelescope affiliate and donor of the Planewave CDK700 27" telescope then invited our guests to speak to an excited gathering regarding their thoughts and feelings before the cutting of ribbons began. 

Dr Pamela Gay (SIUE), our very special guest from across the pond then gave a wonderful talk on the role of the three female astronomers the telescope was dedicated to before she skillfully cut the large red ribbon that officially declared the BCL T27 iTelescope ready to give our thousands of members access to the largest publicly available online telescope in the world.

Dr Amanda Bauer (AAO) an Australian Super Science Fellow was also a delight as she gleefully cut yet another red ribbon draped across the observatory entrance and declared the iTelescope SSO Observatory open for Remote Astronomy! Amanda is a driving force in Australian and international astronomy and is the outreach officer for the Australian Astronomical Observatory  See Video Here

We once again wish to sincerely thank Pamela, Amanda and Neil for giving us their time and being so generous in their words on the day when iTelescope officially presented its SSO observatory and this fabulous telescope to all those that have a hunger to image and investigate the skies of the southern hemisphere above Siding Spring.
