Dear friends of the school-astronomy!

Thank you for your interest in our lunar-parallax-project. So far almost 70 schools from America, Europe, Africa and Asia have registered for our appointment on October 9th. Hopefully we have a clear sky!

There were some questions about the implementation on October 9th. So here's some information and hints:

The technical effort is not very high. You need a camera with a telephoto lens and a tripod. Please take the moon with the two stars in the background: 35Tau and 54Tau. You can see their position and our field of view in the attachment.

So we need the angular size of the field of view of 7 degrees or a bit more. You should choose the focal length of your telephoto-lens. I will use a Canon 6D (Full frame sensor) with 300mm focal length. The aperture should be open. When the photochip is smaller, e.g. APS-C, then you have to choose a shorter focal length.
It is important that the moon and the two background stars (35 Tau and 54 Tau) are sharply defined.
Please take the time to adjust your setup before you start recording. The images need no tracking, if we go with the focal not more than 300 mm.

Please send us your pictures (via dropbox or similar) in JPG or RAW format with the names 03h-00-00.JPG, 03h-00-30.JPG, 03h-01-00.JPG ... after the date with a text file, which contains the following:

  • Height and azimuth of the moon at the observation station during the recording. (Azimuth: south = 0 degrees, west = 90 degrees, north = 180 degrees, and east = 270 degrees)
  • The GPS coordinates of your observation site
  • The names of the observer

It would also be nice if each team would take a picture of themselves and the setup used. If you agree, then we exchange our pictures among each other. This allows your students to determine the distance to the moon itself.

Here again the exact times. Please convert UTC to your respective local time.

All times are expressed in UTC. 

9th of October (3.00 UTC) Moon near Hyades. This is the night from Sunday to Monday.

Please contact me for any need and forward this mail to other interested teachers and students.
Please write to me then, if you were successful or not.

Best regards and clear skys!
