Hi,
I recently bought a Promaster wireless Remote Shutter and may be having a problem with it. Even though I have inputted the same exposure times for all exposures it is coming up with often around half of my exposures being a slightly different length than the rest, around one-third of a second or so, sometimes a little more, when I check their lengths on my PC, then Deep Sky Stacker will show 12 seconds for half of them, and 13 for the rest, for example, for what are meant to be 13 second exposures. I have double checked I haven’t put in the wrong exposure length by mistake. Is this normal for a DSLR and this type of intervalometer to do this? I need to know so I can take it back if this is not normal functioning.
Thanks,
