Installation of meteor detection cameras at SOAO observatory
(17. October 2014)

Departure from Daejeon (KASI) in the early morning hours with a rental car.
All equipment were put safely in the back trunk.
Everybody ready for two days of astro-endeavour.

Arrival at SOAO observatory in the afternoon. Unpacking stuff.

KASI staff and contractors also arrived already and started installation of
video and power cables ...

... struggling to maintain keeping an overview ... but everything is thought of ...

... pulling cables through underground piping system for remote installation. The good thing about SOAO observatory is that pre-formed concrete blocks were already at place (existing) ...

Here is a view of one access point to one underground pipeing system ...

However, the original piping system would have required a 110m wiring of the
video/coaxial cable.
That would have deteriorated the video signal significantly.
Instead a short-cut was made half-way through and the coaxial cable was put through the wall
thereby saving some 60-70m.
The total length of cable from camera to PC is now around 40m.

Here the access point through the (southern) wall of the SOAO education building is visible.
Cables were protected using a hard plastic tube.

Pulling of cables through the ceiling on the inside with the help of Mr. Cho (genious guy) ...

... further pulling and wiring for a clean installation ...

At around 8pm we had a 2hr briefing to prepare for first test
observations using a meteor camera.
This would be the first time the students had a chance to get
real hands-on experience to work with the various settings of the camera and to
explore its properties and their functions/effects on the video image.....

... also properties of the lens were explained. Small exercises were given and groups were formed.

Real practical first-time meteor observations on the outside
premise of SOAO observatory at 10.30pm.
All equipment including computer were used.
The night was exceptionally clear.
However, for simplicity we only deployed one camera.

... but it turned out to be also freezing like crazy ...
so we made a warm-up pause every 15 min or so after experimentation tests.

red colored headlights helped to maintain our night vision when looking up to the sky during the test observations to identify stars seen on the monitor.....
here we are connecting the camera to the PC and turn on for power

... more wiring and connections ... while it was freezing cold and windy ...

First focus test and field-of-view tests ... actually success from the very beginning ... we let the UFO Capture software running for about 2 - 3 hours (while we were inside and warming up) ... indeed after checking we caught our first meteor on video!!!


At 3 or 4 am in the morning everybody was tired and we went to bed to
get rest for next days real/permanent installation

In the morning on the following day the real installation process was started ...

Installation of the red foundation pier that holds the three camera arm.
Anchor bolts (stainless steel) were used to secure a tight fastening.

The pier was then levelled to be straight vertical....

The two plastic boxes are necessary for electronic equipment/installation.
The southern box will
contain the powersupply + fuse and timer.
The northern box will contain the phase protection devices for the coaxial/video cables.

... at times it could look quite messy ... but we managed to maintain an overview ...

Close-up view of the electronic plastic box. The DONG HWA TIMER is the timer
controlling the powersupply to each cameras.
It is set to switch on the cameras at 6pm and switch off at 6am every day.
All other switches are surge protection and fuses to protect against lightening strikes.

The students soldered cables ends to make connections more reliable in this harsh environment.

After the main installation was completed the students started to mount the top part of the three camera pier.

Cameras also needed proper orientation on the sky ...

... elevation angles were measured with proper devices to infer accurate
measurements ... measuring the azimuth was a bit more tricky.

... each camera was oriented in a specific way ...

... more mounting ...



SPECIAL THANKS GO TO: MR. CHO and his helper!!!
