Details:
To accurately locate the center of an upcoming magnitude -8 iridium flare, I used a rig I made that holds a 20 mW green Wicked Laser on a tripod. The Laser can be turned on and left on. I aimed the camera at the end the Laser light that I could see in the viewfinder.
Attached to the setup is an angle finder that enables an accurate estimate of the altitude. Heavens-Above star charts and data were used for the exact details of the center of the flare. The Android app helped as well.
Iridium 76, 04:45:41 CDT, magnitude -8, bright moon, in town, 42 mm, f 5.6, 30 sec, ISO 800, Pentax 18-250 mm zoom, Pentax K-5 IIs body.
