meanwhile, i did solve the problem (not very elegant, i know) with a litte python script and direct controlling the remote shooting contact...:
#!/usr/bin/env python
from time import sleep
import RPi.GPIO as GPIO
import sys
bulb_text = input ("Belichtungszeit: "
bulb = int(bulb_text)
anzahl_text = input ("Anzahl: ")
anz = int(anzahl_text)
i = 0
b = 1
GPIO.setmode(GPIO.BCM)
GPIO.setwarnings(False)
GPIO.setup(25, GPIO.OUT)
while i<anz:
print ("Bild Nr.: ", i+1)
GPIO.output(25, True)
while b<bulb+1:
sys.stdout.write ("\r%i" " Sek." % b)
sys.stdout.flush()
sleep(1)
b = b+1
GPIO.output(25, False)
sleep(3)
b = 1
i = i+1
