(meteorobs) Preparing Meteor Photos for Scientific Purposes
It has come to my attention that some of you might be interested in
photographing meteors for Scientific purposes. If you wish to send a copy of
your meteor photographs to the International Meteor Organization for such
purposes and your photos are from Single Stations, you can send them to
Juergen Rendtel for analysis. His mailing address for such purposes is:
International Meteor Organization
c/o Juergen Rendtel
President
Seestr. 6
D-14476 Marquardt
Germany
If you capture a meteor, be sure to make your print at least 5X7 in size.
Also, include all edges of the negative in your print. You should make the
print lighter than you normally would. It will not look pretty. Remember, this
is for scientific measurements. Esthetics is not considered. Before you submit
any photos to him, please put the following on the backs of each photograph:
* Your Name
* Day, Month and Year (Use Double Date)
*Time of meteor appearance. Use Universal Time or Local with the Time Zone
shown. If photographs are unguided, times should be as close to 1 second
accuracy as possible.
* Apparent Magnitude.
* Apparent Speed (Very Slow, Slow, Medium, Fast, Very Fast)
* Location: Site Latitude, Longitude and elevation and with verbal location.
Such as: Sequoia National Park; Yuma, Arizona etc.
* Camera lens (ex. 28mm lens, f/2.8)
* Film. (Ex. HP-5 push developed as 1600 ISO in T-max developer for 9.5
minutes at 68 deg F)
* Estimated Print Center (ex. RA: 8h39m, Dec: -8 deg)
* Identify any particular bright stars by taping a thin sheet of paper over
print so labeling can be done. This is not necessary for guided images.
Juergen has the proper equipment to make precise measurements for the unguided
images. The photo and information will then be included into IMO's
Photographic Archives for future studies.
