Automated Canon eos photography under linux. was created by martinus
A.K.A. yet another one of martinus' python scripts.
I'm sure some of you may have tried this. I've been playing with it on and off for a while now but I managed to figure out the specifics of taking longer-duration shots in bulb mode with the camera tethered to a laptop via USB.
This should work just fine on a raspberry pi though I've not tested it.
All I need now is for the tracking on the EQ6 to behave.

Code:
#!/usr/bin/env python
# Tested in an eos500D in gphoto2 2.4.14, should work with similar models.
# Camera must be switched to Manual mode, single shot and tethered via USB.
# There seems to be a one second variation in exposure times and a four second
# download delay.
# Free for anyone to use, copy and edit.
import commands
# ===========================================================================
# Set your shot parameters here:
target_name = "example"
save_to = "/home/user/photos/{target}_'%Y%m%d%H%M%S.jpg'".format(target = target_name) # See gphoto man page for timestamp formatting.
shutter = "bulb" # Bulb mode on the camera.
shot_limit = 3 # Total number of photos you want to take.
shot_duration = 90 # length of time in seconds of the exposure keep it above 10 secs.
iso_speed = 100
# ===========================================================================
shot_duration = shot_duration - 4 # account for exposure delay
cmd = ("gphoto2 "
"--set-config bulb=1 "
"--wait-event={dur}s "
"--set-config bulb=0 "
"--wait-event-and-download=1s "
"--filename {loc}".format(dur = shot_duration, loc = save_to))
s = commands.getoutput("gphoto2 --set-config shutterspeed={shu}".format(shu = shutter))
s = commands.getoutput("gphoto2 --set-config iso={iso}".format(iso = iso_speed))
shot = 0 # initialise shot counter
while shot != shot_limit:
print("shot {this_shot} of {total}").format(this_shot=shot+1, total=shot_limit)
s = commands.getoutput(cmd)
#print(s) # Can be useful to debug.
shot += 1
