03 Color Balance for QHY183C
SharpCap will start at the default RGB balance for color camera. Here is the screenshot of the
QHY183C start up
For color camera, SharpCap will show the WB Red/Green/Blue progress bar.
Since the color balance is the ratio between Red to Green and Blue to Green. You can fix the
Green color to 128 and adjust the Red and Blue.
For example, in the image above the blue is 188 and red is 196, green is 128. It looks the image is
well white balanced. If you need more blue, since it has limit of 255. In this condition, you can
reduce the green a little and you will have more room for the ratio.
As we said before, if you are doing planetary imaging you should set the offset value as low as
possible. To make the background close to zero. Then you can easy to get correct color balance.
Otherwise it will not easy to get it. Sometimes the offset of an image is good but you cannot get
good balance.
