David 寫:1. I don't like the long waiting time in photography, and dealing with just a few objects per night.
with F3 astrograph, Paramount and either big enough chip or high QE chip, you can image 100 objects a night like certain research observatory.
David 寫:2. I like playing astronomy with students, and they don't like photography.
it's your role to inspire them get interested on something.
David 寫:3. With an 18 inch, I feel that any observation is possible. I admit that if one only has a small scope, then photography is the only way to enjoy deep sky.
The photo from 18" is more striking than you can see from eyepiece.
David 寫:4. I don't like doing what most people do.
agree, that's French.
David 寫:5. When doing visual, the feeling of having photons from a faraway object reaching my retina after thousands to millions of years is quite amazing. I feel a direct connection with that object.
The "feeling of...." is only a feeling anyway. I keep computer files or even print a hardcopy is solid.
David 寫:6. The 3D feeling of nebula or globular clusters can seldom be captured by photography.
Good photo will do.
anyway, I love observing with you, you do all the preparation, and by the time you annouced what's next you are going to observe and start hopping, I press the key on TheSky and my 8" APO slew to that, dead on.
