Image Description:
This is my first ever DSLR image! Thanks much to Jon L. for letting me borrow his Nikon D100.
Some interesting notes about this image. The vertical "trail" at the bottom, center of the image is a diffraction spike from the bright, mag 2.5, star, Iota Orionis, which is just south of the field of view of this photo. The faint, horizontal line in the lower-right portion of the image is a meteor trail or a photographic defect. Not sure which. The distinct nebula above the main one is M43.
