TIPS
FOCUSING
To achieve best focus, concentrate on a high contrast feature of the object you are
imaging. Focusing on small features such as a moon's shadow on Jupiter or Cassini's
division in the ring of Saturn will guarantee best focus across the entire image.
Once the frames of your video are stacked, the overall brightness of the composite
(stacked) image is usually brighter than its individual component frames. For this
reason, it is best to keep the brightness of the video image seen on the screen
dimmer than you would normally desire. It is important that no part of the image is
over-exposed to assure the maximum amount of detail in the final composite image.
COLLIMATION
No matter what type of telescope you image with, poor collimation (alignment of
the optics) will ruin your chances for a good image. Before you begin imaging,
always check the collimation of your instrument and make adjustments if necessary.
Refer to your telescope's owner's manual for instructions on collimating the optics.
FINDING OBJECTS
At first it can be difficult to locate individual planets due to their relative brightness.
To make it easier to initially find your object in the imaging window, increase the
brightness and gain controls on the Device Menu Properties. This will allow you to
better see the object as it passes through the imaging window. Once the object is
located and centered, you can adjust the setting until the object is at the desired
brightness and contrast.
HOW LONG TO TAKE STREAMING VIDEO
You may think that the more frames you record the better. However, there are
