Hostels + boarding houses
Food + drinks
In contradiction to other star parties you don't need to cook or
to barbecue for yourself. You get delicious and inexpensive foods and
drinks nearly around the clock.|
Petra and Roger Franke offer home cooked dishes at 09:00 in the morning to 02:00 in the night.
We like the intimate flair of the HTT:
Our "H-alpha bar" is an important
meeting point where you will get to know many astronomers... interesting
discussions and talks happen here.
Our northern meadow is reserved for photographers. There we have
sockets with 230V AC. Please have cross-connectors and extension cables
At the large southern meadow you find power supply only at a few points.
Please inform you before you camp there.|
Please pay attention:
Our power supply delivers enough energy for driving telescopes and for
charging notebooks. But our electrical capacity is not unlimited. Please
avoid plugging in consumpting devices.
Toilets and lavatories
At our place we can use the building of the local sports club
which contains toilets and cold & war water. If you want to take a
shower you can use the club building of the Football club Kolochau - which
is 3 km away.|
During the day we recommend a visit at the nearby lakes for bathing
The usage of green laser pointers is
forbidden. Exceptions must be allowed by the HTT team. Please do not
play music and avoid loud noises at night time. |
Please avoid the usage of white light. You should have special care of your car which may
switch on lights when the doors are opened.
Screens of notebooks necessarily only at night with
excessive use red-light film!
When leaving please take all waste with you. We had never problems with
that and thank our visitors in advance for their exemplary behaviour.
Lectures ... Workshops ... Cultural life ...
Please found in the following the program of the 12th HTT.
Please keep in mind that small changes may occur. We inform you with loudspeaker announcements which are usual in
German. Please ask your neighbor if you need a translation.
The meeting starts at Thursday. It is possible to come to the area a day earlier, at
Wednesday afternoon. Please keep in mind: All times are

Friday, Sept. 23th, 8:00 p.m. and Saturday, Sept. 24th,
3:00 p.m. and 8:00 p.m. -
Public observing session in teh
Elsterland observatory at the northern meadow.
Since August 2010 we have the weather station at the observatory running. It gives al large amount of
current weather data e.g. the UV index, solar radiation, moon phase
and SQM measurements with statistics!

Friday and Saturday, 9:00 p.m.
and 1:00 a.m.
explains and shows our yearly sky tours HTT Skyguide 2011. Meeting point is the reserved area near the Giant
Dobson at the north west corner of the main meadow.
Friday, 2:00 p.m.
Beach Volleyball tourney
At the northern meadow, 100 meters west of the observatory, we have a beach volleyball area.
Here the young people from Jeßnigk go in for sports quite often. Normally, at the telescope meeting this
place is not used. We want to change this: In this year all sport fans at
the German Astro-Côte d'Azur ;-) are welcome to get a sun burn playing
volleyball. This is quite a good alternative to laying around in the sun and do not much. ;-) :-) ...
We are interested to see whether you like this idea or not. We hope to see a great amount of players.
Enjoying the sport ist the most important thing. It does not play such a large role who is the winner.
May be we have enough players to form some teams which can play against each other. Please drop information
in advance if you like to play in a team.
You can send e mail or inform the staff at the admittance point until Friday 1:00 p.m..
If there are many teams we intend to from groups of four, like at an world cup. The winner and the next team will be admitted to go to the play-off which is intended to take place at Saturday afternoon. The winner gets a real cup!
We are looking forward to see interesting matches between teams with players from near and far.
Friday, 7:00 p.m.
An evening dedicated to Dark-sky.
NAfter the tragic disaster in the Japanese nuclear power station politicians talk about producing energy in
an ecological way. We've rarely seen such an agreement between policymakers of different fractions. We believe
that ta very important effect could be reached by reducing the nightly illumination which was driven to an
amount beyond every security need. This could be done immediately. The astronomers in Germany and Europe
should speak loudly with one voice and work together. This evening gives a chance to bundle the
activities of the whole astronomical community and to agree about way and strategies to a new
We are looking forward to hear lectures from well-known experts in this area.
- Dr. Andreas Hänel (University Osnabrück, head of the
Planetary Osnabrück and the German dark sky section
- Jan Hattenbach (Observatory Aachen)
- Martin Gembec (Initiator of the Czech-Polish
Dark sky area in the Iser mountains)
Additional we'll present first results of measuring the sky quality with the help of
ELSTERLAND-STERNWARTE's SQM device, data of their cloud sensor and all sky images. All values are measured at a minutely base.
beginning at August 2010).- We are convinced that the defense of a dark sky is a valuable target. To
illustrate this we show here a photograph from HTT 2010 which shows
the zodiacal band in total and the gegenschein - autor:
Petr Skala (CZ).
Please note the planet Jupiter near the right border which was near opposition at the time of the photograph. This may be the first image of the rarely seen cosmical glow from a location outside fro, high mountains.
We plan to discuss the dark sky problem with local politicians at Friday evening. At Saturday 2 p.m. we hope to dismiss first steps and initiatives for a national or even international cooperation between the dark sky activists.
Friday and Saturday from 9 p.m. and from 0:30 p.m.
The Sky Quality Meter in practical use
All users of SQM and SQM-L devices are invited to compare their measurements, which were taken at the same time. This comparison of SQM result gave a good feedback in 2010. The results are remarkably:
here - every SQM owner gets the chance to calibrate it's SQM device!
Saturday, 24.09., 11:30 a.m.
The cultural life at our star party: Open air Brunch
(with beer and live music):
Dr. Erhard Hänßgen + Frank Werner from
the "Orchester der Bergarbeiter Plessa" [miners' orchestra] - this year
with contemporary guitar sound...
Friday evening or Saturday evening:
Live-talk with ISS staff
We transmit the talk with loud speakers so it can be heard everywhere on the place.
The communication of ground stations with the ISS uses reserved frequencies. The communication can only
established in the short period in which the ISS can be seen at our sky. Only then we can reach the ISS
in ultra-short wave band. We don't know the time planning chart at the ISS and don't know whether
somewhere spare time in front of the transceiver.
But from our technical equipment it is possible. And if it works, it would be great! An if the spaceship
covers important areas of the sky, e.g. the Vega like in the penultimate year, we have the right addressee
for our complaint... ;-)
Sa., 1:00 pm - around 6:00 pm Uhr
Small but delicate - our Fair: AstroTechnik- und Vereinsmesse (ATV).
As in former years we are glad to present astronomical companies with its' interesting quotes:

Beside this astronomical clubs and observers will tell us about their activities and projects.
year we offer all astronomers a very special event:
- Thomas Heising + Steffen Behrndt: Workshop Grinding your own
astronomical mirror (Theory with many images
+ Practicing) - The workshop is apporpriate for a real grinding beginners,
with the thematic priorities:
- Which materials can be used
- Fundamental steps to the grinded ond polished mirror
- the Foucault test and the Ronchi test
- preparation of a polishing tool
- Corerecting the mirror by using the Foucault Test...
The workshops takes roughly 2 hours
- Uwe Pilz holds again the workshop
Workshop How to calibrate a Newton telescope and tells about
the activities of the
