Just to add a comment:
Most dslrs, if not all, use black frame subtraction, or can use black frame subtraction (it generally is an option in the menu) for long exposure times. If you need to do multiple shots, it is a matter of taking those yourself and stacking them.
Kind regards, Wim

If you have a tripod or similar, yes, but for those cases where you can't use that, this system was a great help. I wouldn't trust stacking of handheld sequences very far.
