Thanks here’s a link to a 198K image if are interested and you want to have a look at the full size image. http://img.photobucket.com/albums/v7...ridium61A1.jpg
There are star trails in the bigger image; wide field smaller images hide a lot of stuff. A bit of planing is required but the weather is the big factor (rogue clouds). I just print out the Iridium Flare predictions for my location from Heavens-Above
set the polar axis of a gem mount up at the predicted Altitude and then pick the mount up and rotate it to point to the predicted Azimuth using a compass. Open the shutter 10 to 15 sec before the Flares predicted time.
