Peter zimnikoval s aid before transit

Peter Zimnikoval´sAid Before Transit

Our friend has very open mind and he prepared for us 2 aids.

  • 1. Venus mask

    This mask may be useful to determine times of 2nd and 3rd contact during the transit of Venus across the Sun.

  • 2. Transit simulator

    This software simulate transit of Venus across the solar disc on June 8, 2004. The software gives a basic images about progress of an astronomical phenomenon which nobody of us seen. Therefore may be useful as the training before observations. It shows problems with measurement of time of single contacts, too. But it is only poor imitation of the reality.

    Both you can find on www.venustransit.sk


Programme of szaa

Programme of SZAA

  • Construction of web-pages www.venustransit.sk

  • 9 observational projects

  • Taking some data

  • First and fourth contact in focal plane of coronagraph + color CCD camera SoftHard Technology

2. Second and third contact in 16-cm refractor with 2x teleconverter (f=4900 mm) + bw CCD camera SoftHard Technology

3. Details of transit of Venus in 16-cm refractor with 2x teleconverter + bw CCD camera SoftHard Technology

4. Transit of Venus: taking pictures of whole solar disk with Venus 300 mm teleobjective with 2x teleconverter (f=600 mm) + bw CCD camera SoftHard Technology

5. Video of Transit (90/1000 mm refractor + CCD TV-camera Oscar + DCF-time inserter + videorecorder)

  • Popularisation

    6. On-line web-camera on pages www.venustransit.sk

    7. Web-camera on azimutal mount

    8. Direct „classical“ photography in focus of Coude-refractor (8 cm diameter of Sun in focal plane)

    9. Grant for secondary school student – reconstruction of Maximillian Hell´s observation on June 3, 1769 in Vardo


Our problems

Our problems

  • How determine a correct time of contact, exactly don´t known:- where is solar limb?- how large is Venus disk on our pictures?

  • On 4900 mm focus is diameter of Venus theoretically 206 pixels. Uncertainity 1 pixel means in time uncertainity about 6 second...

I don´t understand, how in 1882 and before would have taken some precise data ;)

Clear sky and good luck!
