Focusing Tips in K3CCDTools 2

Here are some focusing tips. Some of them are better for star focusing, while other are better for surface objects (planets, Sun, Moon).

• Use WDM interface in preview mode, which provides very fast preview. I recommend to use 10fps, which is fast enough while it retains good picture quality for focusing
  
  
• Use Zoom 200% in Video Capture mode for detailed focusing (requires faster computer)
  
  
• Use Brightness Level Meter with unsaturated star for measuring star's peek brightness. I recommend to use Low pass filter to reduce effect of scintillation (seeing variations).

• Use FFT Dialog for surface objects and watch quality graph in the middle part of dialog. The higher the number shown in the graph the better is focus. The focused object must be in the center of the screen.

Note: I plan to implement a special tool for focusing in near future.
