Canon 60D processing time

Hi I have a canon 60D with a 18-135mm and a sandisk ultra 32GB.
I have been trying to shoot long exposure at night (60 sec+), I'm wanting to do star trails.
The problem I have been having is after the first picture has been taken, it says "busy" and won't let me take another shot for up to twenty seconds. I also shoot in RAW. please help

Turn off Long Exposure Noise Reduction.

Yep, it's LENR. Once your exposure is done, Long exposure noise reduction take another exact picture... but with the shutter closed. It compares the 2 images, and deletes the noise and hot pixels associated with long exposure shots.

While a great feature, that works well, it does add time to your shooting. If you shoot a 30sec shot, it will take another 30 sec. shot. 30:00, you have to wait another 30:00! When activated, it starts at any exposure of 1 second or longer.

See page 254, attached for your convenience.

Heya,

As others stated, long exposure noise reduction. Turn it off.

I do 4+ minute exposures at night on a tracker. It's brutal to sit and wait with that enabled. Plus, it's nothing great that you cant already do in post.

Very best,

Thank you guys for your help
