Hi all,

With my Nikon D7000, I have gone from 30” subs to 2’ to 3’ with results getting considerably better the longer the individual subs. Tonight I plan to go 5’. Too long for a DSLR?? What is the maximum exposure for a sub before running into problems? (Is the main problem bloating of stars?)

Also, should I be decreasing the ISO if I increase sub length?

Thanks for all you help,
Stéphane
