Thz Kwan.
People suggest using MF rather than AF of the camera, then adjust the focus on the scope to get a clear image. Which way is better?

Hi Alex,
 
I will say it is a personal preference.  
 
However for cp4500 which is having the smallest LCD display, manual focus is not really workable. May be other model having a bigger display will allow MF.
 
good birding.
