Frustrating failure . . . D7100 intervalometer issues

You can do this without using an inveralometer at all.... put the camera in "continuous" shooting mode. Dial the shutter speed to 30 seconds. Lock the shutter down (e.g. using the basic shutter button on your wired release to press-and-lock it.) The camera will now take images continuously... one every 30 seconds.

Thanks for your feedback

Yes I have one of those too. This one is 267". I couldn't stay longer cause I didn't want to get a ticket for public urination. Too much info?

My question is would it be easier to control the light pollution with a stack of images rather than a single one?

You need to set the interval a few seconds longer than your exposure time. If you want 30 second exposure then set the interval to 34 or 35 seconds and it will work and not give the dashes between the exposures. If I remember right you have to give it that extra time because you can't set it to the same interval as the exposure time and it work right. Hope this helps.

Yep. Thanks for your response.

My question was about if it was better to use 33" single exposures or to use 4'55" 9 burst exposures.

Since my original post, I've done some thinking and the 4'55" only saves 2 seconds of exposure. CH on the d7100 is 6fps so I'm probably losing about 1.5 seconds to cycle time. 1/2" isn't going to make much difference.

The only reason I could see bursting be useful is if I wanted to take more that 999 shots. I don't think I'll need over 8 hours of 30" exposures.
