Connect the equipment into an output on a circuit different from that to which the receiver in connected.
To get more of the moon in the image, a focal reducer will need to be used. This simple method of imaging is exactly how the camera is used to capture terrestrial subjects during daylight hours. Also, wind will move your telescope and affect images. Since the exposure is very short, it is not critical that the telescope be precisely polar aligned. Try using different color filters on a planet to see which filters help best show planetary details. Try several different settings to get a feel of how the camera controls work and affect the resultant image on the computer screen. If you are using Windows Vista, the AutoPlay window will appear first.
A shielded cable must be used when connecting a peripheral to the serial ports. There is a limit to how large a focal ratio your telescope and seeing conditions can handle, however.

The camera simply is inserted into a focuser in the same way as a standard eyepiece Figure 1. Depending upon the viewing conditions you may notice that the image goes in and out of focus — this is due to viewing conditions. For detailed information on the image processing software consult the websites of each software Provider. Any images captured with the camera will now also be at full resolution. Retighten the thumbscrew on the focuser drawtube when done. If frames are being dropped this will be displayed and the frame rate or resolution should be set to a lower value to prevent this.
You will now need to refocus the camera for the centered object. To increase the effective focal length of your system, use a Barlow lens or other type of tele-extenderlens. To return the camera controls to their default settings, click the Reset button. When installation is complete click the Finish button. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: Reorient or relocate the receiving antenna. Since you will be taking multiple images over a period of time, it is important you have a decent polar alignment in order to keep the planet within the field of view of the camera. Solar Filters Warning: Always use a full aperture solar filter when viewing the sun.
The Output Size can be used to change the image size if desired; the sharpest images being at the native resolution of 320x240 and best for saving large movie files and the highest resolution 1280 x 960 is best for group viewing and as a focus aid. Refocus often throughout your imaging session. Enter a value such as 50 Megabytes or higher. Adjust the step for the time being. Focal Reducers and Barlow lenses available through Orion, check the catalog or www. Here you will find the Brightness, Contrast, Gamma, Hue, Saturation level of color , Sharpness keep this low as it can add noise , and Exposure controls. Otherwise, the image scale may be too small.
To this end, having a motor drive at least single-axis will also be helpful. You are now ready to install. Keep in mind that when the focal length is doubled, the image will become four times dimmer, so a longer exposure may be necessary. Make sure the securing thumbscrew on the focuser drawtube is tightened after the camera is inserted.
