Mode : Aperture Priority
Shutter : 1/18 second
Aperture : F5.8

Telescope at 20X, camera at optical 3X

A lot of patience and failure

good birding

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.
