Easy Digital Camera with Zoom Lens Instructions

Setup Camera: Set focus to manual at infinity and exposure time to as short as possible, turn off digital zoom.

Point Camera: Use the map or a finder chart near you location to determine where the SRC will firt be visible and point your camera in that direction.

Shoot SRC “Meteor”: Take as many photos as possible while you can see the SRC. Use a tripod and video head to minimize vibration.

Record your location (i.e. 1234 Main Street, Elko, Nv 12345)

Addition Steps to help Make Photos More Useful to Scientists

Calibrate Camera Time: Set camera clock by calling local time number.or if you have a shortwave radio, by listening to WWV (5, 10, 15, 20 MHz).

Record your location: Save a waypoint (latitude, longitude and altitude) using a GPS receiver

Calibrate Camera Sensitivity: Without changing your camera settings, take several exposures of planets such as Jupiter, Saturn, Venus, Mars and several bright stars such as Spica (a Vir), Sirius (a Cma), Procyon (a CMi), Arcturus (a Boo) and the Moon before or after the SRC passes by. Use "text" insert and rename your file to indicate what object was recorded. Websites such as Heavens-Above can provide full sky starcharts for your location showing the stars an planets.

Take Dark Frame: Without changing the settings, put the lens cap on and take an exposure of the same exposure time as the one with the SRC trajectory.

Take Bright Frame: Without changing the settings, take an exposure of a homogeneously illuminated surface. That can be the sky above you during daytime on a clear day, or a piece of white paper illuminated with a diffuse light.
