Site Last Updated June 29-07-2009 (Dishes) Welcome to The S.E.T.I Research & Community Development Institute Limited web Site. It is our intention to keep you informed on the happenings and ongoing work of the Amateur SETI movement in Australia. We are a non-government, non-profit organisation that has as it's members, some of the brightest minds in the world of science. We exist due to the generous assistance of our sponsors and friends. Some of these organizations and individuals are listed below and we are grateful for their contributions to our cause.
Our Mission
SETI research
group came into existence in 1998 when attending the
SETI In the 21st Century conference at the University of Western
Sydney, Campbelltown NSW. We were a group of Seti League members
attending the conference and in between the various papers being
presented, the delegates had the opportunity to mix and enjoy some
informal discussions. After returning to Brisbane (QLD Australia) an
informal meeting with some of our
SetiLeague
colleagues occurred and we decided that our group should get fully involved
with designing and constructing our own SETI Observatory. After all,
the Southern Hemisphere offered the best astronomical viewing
opportunities in the world. The task
was enormous. We needed land, electrical power, equipment, willing
labour, money
!!!!! Money????
How and who would be so generous to help us out? Well, as it turned
out, many individuals and companies came forward to assist us with
all aspects of the design, and construction of a facility that would
rival anything done elsewhere in the world. SO, OUR MISSION was to
do all of the above on a shoe string budget. Yeah Alright, pull the other
leg!!! Seriously, we have done it. Our sponsors and willing labour
force have done the seemingly impossible. We now have a block of
land (2acres) in Southern Queensland with a 13KW Solar Power
Station, 2 large 40 Ft dishes, a 14inch Celestron C-14 Optical
Telescope facility with C.C.D. camera, accommodation for caretaker and
visitors, equipment buildings and most other things to allow us to
start doing what we set out to do, provide a first class
Astronomical facility to assist the rural educational community and
to provide access to both Radio and Optical telescope facilities
that are accessible to the future scientists of Australia. This website
aims to keep you informed as to our progress. We hope that you enjoy
your visit with us. We will endeavour to make your visits here
enjoyable. Many sections of the website get updated. Just cruise
around regularly and keep up-to-date with what we are up to.
Oh, and please sign our guestbook we value your comments. Special Web Sites and Features
From Our Activities in Boonah
News News SITE WEBCAMS are Here Now !!
Broadband ADSL is now installed and working at the
Observatory site so we have setup three webcams for you to look
at. Our local area network is finished being configured and all is
looking good. The new cameras will provide new pictures every 60 seconds of the site in
Boonah. Stay tuned. Not only will this monumental event provide cute pix
of our activities but it will allow us to easily control the site
remotely. A huge development for us. Our fourth and final webcam will be
active at night and will be pointed at the sky. This will allow our
northern hemisphere visitors to get a look at the southern hemisphere
sky almost in real time.

Saturday you will see us working away at our current project.
ENJOY.
The First Dish is now completed
Well, after several years of planning and making parts that were
missing, the first of our 40 footers is ready for some
Drift Scan Radio Astronomy. Below is an image of the finished dish
sitting on a concrete slab. It has taken us 25 man days to prepare and
install the new surface plates. Each plate is bolted on to the main arms
and other support structure we had to fabricate. Quite a sight it is.
The work load was very high and much was done standing on top of ladders
The
outer section (segment 9) is made from Aluminum fly screen mesh and was
very awkward to handle. We had to make a special support to mount it on
so it would not flap around in the breeze. The rest of the dish is a
mixture of the old screens that came with the dish and many new one's
that we fabricated on site. The original screens were punched with holes
about 15mm in diameter. You can see them as they look different in the
images. Our trusty team of volunteers need a mention and some thanks for
their efforts. Mike Boggan and Deb Skilton have worked hard over the
past 6 months to get this structure finished.
Deb at left was a keen assistant
when
Mike was not able to be on site. Seen at left is Deb finding some nuts
and washers that fell through the holes in the dish. Yep I dropped them
!! Noel Welstead can be seen drilling the holes to attach the mesh to
the outer perimeter of the structure. This was a frustrating job that
saw many pin pricks from the edge of the mesh. There was many
profanities uttered during this phase. The feed horn and electronics
were completed about 18 months ago and the support structure installed
around that time. We needed to get this hauled up using a crane at the
same time we moved the dishes around.
 The
delicate nature of the outer skin including the mesh supports had to be
made on site. This was an arduous task as each piece had to be measured
and cut to size for each segment. Much of the work included drilling and
tapping the holes to accommodate the stainless bolts and washers. At
right you can see one of the screens that are punched out with holes. At
left you can see a panel with the mesh attached.
 The
first two layers (plates the same shape) were installed some time ago to
trial how things would go together. There were some initial problems
with the Stainless nuts and bolts seizing and locking prematurely. We
had to twist and snap them to get them off again. This caused us to
re-think what we were
 doing.
In the end we decided that the simplest remedy was to lubricate the
bolts. This worked and made things much easier for us. After installing
the first 3 layers Mike Boggan got inside and taped the joins with
Aluminum tape. This gave us a near mirror finish and looks quite
startling to look at. As well as looking good the tape reduced the
effects of a not perfect surface which is quite important if we want to
move our search higher up the band, maybe to 2 x 21cm or 2840mhz. Above
right is Noel standing in the dish to show a relative size
comparison. The surface is quite smooth and one needs to take care when
walking up the side. You can see the entry hatch we made to allow access
to the inside for cleaning and repairs if necessary.
 Because
of the highly reflective surface of the
mill finish Aluminum
we decided that we should paint the surface to ensure a more stable
temperature variation to reduce excessive expansion and contraction of
the plates. We had noticed that during the day when it was hot, the
surface had expanded quite a bit. And when the dish was in shadow late
afternoon the surface had contracted noticeably. Noel's relatives Colin
& Lynnette Brooks cam on site for a weekend of painting. Noel did the
cutting in while Colin did the rolling. Quite a nice finish now and the
surface temperature variations are much less than before. We decided
that it was time to test the LNA's to
 see
if they were still working ok after nearly a year in the elements. Mike
and Noel hooked up an
ICOM
r8500 receiver to check out the systems. Looks like one channel is
down so soon we must climb to the feed point and have a look. Well
finally the dish is painted and looking great. Thanks Col and Lynnette
for the help and a great weekend on site.
Next
we need to start prepping Dish2 cause "while your Hot your Hot" and we
need to make use of the cooler winter days to work in such a reflective
environment, not to mention the heat (who mentioned the heat!) so we did
some cleaning up around dish2 and got it nice and level for the bolt
tightening event next weekend. In the background you can see dish1
gleaming in the sunshine. Oh what a feeling !
Finally a
picture
of our trusty workers. From left to right is Cathy Boggan, Bobbie Pahl,
Bob Pahl, Debbie Skilton and Mike Boggan (holding drink). The assistance
of volunteers is a great way to get things done and we are very grateful
for any assistance given.

Planet Quest
The fifth-brightest star in the night sky may be home to planetary
system similar to ours, according to new research by astronomers at
the Royal Observatory in Edinburgh. Computer modeling techniques
have shown that the structure of a faint dust disk around Vega can
be best explained by a Neptune-like planet orbiting at a similar
distance to Neptune in our own solar system and having similar mass.
