a workaround might be to shoot shorter exposures and merge them using s/w ( http://www.startrails.de/html/software.html ).

There is a Mac version called StarStax as well.  Very similar, if star trails doesn't have a mac version yet (it didn't before).

I have this problem with bulb mode on the NX20 where on long exposures, like say 4 or 5 minutes, the dark frame subtraction removes the entire image, there is nothing left but black.  So confused, anyone else use bulb mode?  PS you can't turn off DFS in bulb mode.

For now I can stack 30 second exposures in continuous, but it takes so many shots to get a reasonable length of time.
