CCD vs Film? Lots of time vs no patience? Alright, this is your place to discuss all the astrophotography what's and what's not. You can discuss about techniques, accessories, cameras, whatever....just make sure you also post some nice photos here too!

Great shots Jiahao! The title 天龍回歸 is very well matched to the theme.
By the way, for this animation, is the "debris" after the meteor burnt out "debris" or just merely cloud that passed by. I am guessing the later as if it were then it would have been hovering on the sky for quite some time given the frame rate you gave. But, I would like to have a confirmation from you.

Hey Robin,
The trains are not really the 'debris' of the meteor, but mostly hot, ionized gas produced by the frictional heat, thus emitting some visible light.
The time span for the animation you quoted is roughly 10 minutes.

Thanks a lot! That makes a lot of sense.
