I have never shot with intervalmeter for the purposes of image stacking but want to at least try. I am going to try star trails but my question is this: Should I turn off in-camera long exposure noise reduction when shooting for image stacking?
When i shoot at night and the the in-camera long exposure noise reduction is on, the process often takes minutes before I can shoot again. If I want to shoot continuous star trails would this create gaps? If I turn the long exposure noise reduction off I should be able to shoot continuously without the extra pause but will noise be a huge issue or will image stacking also control noise.
