    Mark your calendars for August 12th. The Persiads (sp?) meteor showers will be at their height that night. I've been skunked the last 3 years with cloudy skys so I'm hoping for clear skys that night.

    Long exposures of 30 minutes or more should give cool star trails with streaks of meteors shooting through.

    oooo!!! I will try to be out there. We usually get skunked due to smog more than anything that time of year, but when it's clear, it is a sight to marvel at. :D

    Be careful of very long exposures where the skies are light-polluted. You may just end up with fogged film. Make some exposures beforehand of an area of the sky with stars of known magnitude - preferably 1 to 4. Consider meteor trails to be 3 - 4 magnitude. If the exposure fogs out 3rd maggie stars, you will have trouble distinguishing the meteor trails. Also take the opportunity to locate the shower's radiant. 45-55mm lenses [on a 35mm rig] are about right for the job. Lens shades matter.

    While waiting for Aug. 12th, you can sharpen your technique by catching satellites most any old night. The place to find out where and when to point your rig is:
