Long exposure questions
11 months ago

I enjoy taking long exposures and am considering stacking a series of photos for star trails.

The way my camera is presently set up, it takes a period of time equal to the exposure duration to process the image.

What is the camera doing, taking a black screen shot?

Anyway, this time is obviously wasted when trying to take continuous shots for star trails without empty spaces in the trails.

What am I doing wrong.  Is there some settings I need to change to take back, to back, to back long exposures?

Also what ISO are you using?

I am using a D90 and a D7000.

I will thank you ahead of time.

I can't help you. Sorry. But, if you can't find what you need here, try the astrophotography forum. They should be able to shine some light on this matter.

I think you need to shoot at least ISO 640 for astrophotography at least so you can pick up the light small stars emit.

Turn off long exposure noise reduction in the menu. It takes the same amount of time as the exposure to clean the image.

Same job can be done after in post if you need and your camera will be much faster

Thanks.  The exact answer I was looking for.  Again, thanks.
