Observer: Bob Yen
Location: Mojave Desert, California
Date: February 8, 1997 11:30-11:45 UT

First image is an entire 8" Schmidt-Camera 35mm frame (4.5 x 6.5 deg), slightly narrower than the view of a 7x50 binocular. Narrow gaseous tail upwards, curved dust-tail to right. Note the strong ion tail, and the dimmer diffuse dust tail (foreshortened length, due to viewing geometry). Note the deep-sky objects M27 (Dumbbel Nebula, planetary) and M71 (open cluster).

Second image is a telephoto shot, using a Nikon 300mm/2.8 EDIF lens on 35mm. It has the same FOV as the above Schmidt Camera image. Note how the color shot inherently "spectrally distinguishes" the ion tail (blue) and dust tail (yellow) Note the deep-sky objects M27 (Dumbbell Nebula, planetary) and M71 (open cluster) in the same frame.
