Flash issue

[HKFEVER]

Please advise how to set the flash for the following:

- I want the MKII to take 2 to 10 sec night scent;
- And I want the flash to flash just before the shutter close.

So I can have a very shape background night scent and have a good expo foreground.

second courtain sync.
One of your custom functions on the flash, not sure which one on the 580
