format (AVI video, BMP, or TIFF image
sequence). The FIT image is only
available in the RAW (Mono) mode. If
you choose the RAW format, AVI files
will be saved as monochrome AVI; its
data file is only one-third the size of the
color AVI. Thus, this mode can be used
when tight on disk space, or, when the
machine speed is not very fast. Later,
through post processing software one
can achieve the color images. Set the
file location, file name, shooting frames
and other information. Click REC to

2.2 color balance
Under normal circumstances, the color
balance is correct for a daylight shooting
environment, and, screen colors are not
adjusted to restore the color of the object.
Astronomy objects are different and
therefore need to be adjusted.The color
balance of the three RGB channels is separately adjusted for image
color correction. The color balance adjustment range of is 0-191,
each color channel individually adjustable, and one can increase the
intensity of each color channel.
manually adjust the white balance: Manual adjustment
of the white balance is the most accurate and most versatile method
to achieve good color correction. Put a blank sheet of paper in front
of the CCD before adjusting for the current lighting conditions. The
location of this white paper should just fill the screen of the CCD
image. The bar on the bottom left of the Histogram column allows
you to observe the Color Balance. Under normal circumstances, the
RGB channels appear on the histogram in three locations and do
not overlap each other. Using the RGB sliders to adjust the Color
