發表於 : 2010-03-19, 23:37I probably would not use 5x with LS35F. Even I don't go over 2000mm most of the times with LS100T, otherwise the exposure is too long, and poor seeing usually does not support such high magnifications. Usually, I prefer smaller magnification but sharper image with less exposure time and less gain.

人之常情是追求更好的望遠鏡，高分解率、大口徑.....
但Willis你把一台35mm口徑的小日珥鏡的能力很優美地表現出來了

I don't mean that! Just cannot process the image, not the scope...
