Imaging at f/22 | Planetary or |
| f/20 is a great way to image the planets and features on the moon. With the |
| PixCel CCD camera and optional Color Filter Wheel, it is easy to take |
| images of planets also. When imaging the planets, very short exposures are |
| needed. Many cameras have trouble taking images under .1 seconds. The |
| PixCel camera can image at .01 seconds exposures due to the design of the |
| CCD array. The exposure lengths range from .03 to .1 seconds on planetary |
| images. Focus is critical as is good atmospheric conditions. Generally you |
| will take one image after another until one looks good (see AutoGrab feature in |
| the PixCel Operating Manual). This is due to the atmospheric “seeing” condi- |
| tions. For every 10 exposures you might save 1. To image at f/22 you need to |
purchase a 2x Barlow and a
