Description

Composite image. Shot for several hours using a static tripod and my D90 with tokina 11-16 at 11mm f2.8, ISO800, 20sec. Background stars produced from integration of 60x20s star registered images combined with foreground from unregistered images. Meteors were selected and combined from the star registered images using substitute with preview and pixel math. Due to the star field movement and distortion with the wide angle lens (didn't try to correct) some frames would not register so two meteors are manually approximated for location. Couldn't include quite a few others that were out of frame for the reference image used for registration. Was thinking I might be able to mosaic to some degree but no chance with the uncorrected wide angle lens distortion. Guess I should use a star tracker next time ;-) At least I got a few meteors in the composite and really enjoyed the active year for the Geminids, we counted 46 in 15 minutes at one point this night!
