Help me understand astrophotography

[Landofsmile]

Hi,
Real noob here. Can the kind bros here help me understand what is astrophotography and time lapse astrophotgraphy.
Astrophotography means taking the stars in a dark night with your camera set at bulb mode and try to expose as long as 25-30 seconds.
Time lapse astrophotography means setting the camera with the above setting but activated thru time interval to take multiple shots or at least 200 shots and have it stitched together ( not sure i'm using the correct term or not ) and play it out as video thru some special applications.
As i had said above, i'm a real noob and not sure my above assumption is correct or not. I did google for this infos but what i see are only method to take stars during unpolluted night.
Thank in advance for the simple explanations on the this.
Regards

Hi, I'm not into astrophotography but I will try to explain in the simplest terms I know about it.

From what I understand of your question...Is that you want to make photographs of night landscapes
that include foreground and night sky, eg. trees,buildings,natural landscapes,beach scenes,etc in foreground. Or in simple terms starry,starry night.Also note that most probably if you live in a city that chances are better if you travel to the countryside in your country because of light pollution in city areas.

Technically what you are recording are little specks of starlights which by the time it is recorded
in digital has already past in time as an event because light takes a finite time (very,very far away you can't imagine ) to reach you on planet earth. Speed of light is 386000 miles per second.

Timelapse is basically still photographs made at regular intervals and joined together like a video
as if you are using a video camera because it will take a long time for the star's position to move
through the night sky.It's a speeded up version you can view in a matter of seconds instead of hours.
Our chinese expression for this is "tan ku ku" (wait long,long) very boring right? Another thing is the star trails move in an arc (circular) because you are on planet earth and it's also rotating with respect to you on land.

In essence you are making a wide angle photograph but you can also do a portrait of the stars by using a telephoto lens in this case a telescope of the newtonian design (mirror lens).This cost
money so don't try it until you know what you want to see.Better to enjoy what other astrophotographers have done.

Here are some links and the 3rd. one tells you what settings and the how and why of astrophotography.

Hi one eye jack,
Really appreciate you taking the time to explain and also the links. To be frank, your explanations and links has made me understand astrophotography better. Thanks once again. Will try and hopefully will share some shots in the future.
