With cameras like Anthony's, you can go 1/exp, so if you want 1/20s exp, it'll do 20fps.
But the DMK is limited to 15fps or 30fps, and if you want an exposure in-between, you have to pick the slower frame rate.
Thanks Mike, I wasn't aware of the frame rate restriction with the DMK. I have always left it set on 30 fps. This means that all of my Saturn work for this apparition has been at 15fps as I have been using exposures of 1/27 sec for the R & G channels and 1/19 sec for the B channel.

Obviously for Jupiter this is not a problem, it is so much brighter. When the rings of Saturn open up again then 30fps will be obtainable for me as I will be able to go to 1/30 sec exposure, that is based on my capture settings from last year. Thanks again for the info, it is nice to have a better understanding of my equipment, it will help me produce better results.

Thanks Bird, I thought your image was a real rip snorter.
