今天我也有看，但沒有David精彩的技巧和"細"鏡，只好用眼睛去享受一下。

最後也影了。

Cool! The best 'photo' can only be enjoyed by having those photons from the sun die on your retina.

H-alpha and CaK can be seen, although CaK is easier if the aperture is bigger. For most students, white light is always the one that they can 'understand' most easily when they look through the eyepiece.

My eyes are not sensitive to CaK. So I need a bigger scope. :?

none of our eyes are "sensitive" to Cak, it just can be seen with 60mm aperture under daylight.
