Hi guys,
Been researching on making Barn door trackers and people always mention "Tracking Error".
So a basic single arm barn door with curved rod is apparently only good for 15-20min before the tracking error is quite bad.
Does this mean you have to redo the polar alignment after 20 mins? or just reframe the shot in the camera due to it "drifting" through the frame.
And one last silly question. I have a barndoor tracker, and I use it with the hinge on the left hand side of the tripod. I have to use my tracker in reverse (close the doors together rather than drive them apart) to have it track. If I drive apart my star trailing gets worse..
All the other users I've seen on these forums and online, use there hinge on the left hand side but drive the doors apart and have no issues.
I only ask this as pulling the doors together introduces some other problems. (the gear on the rod wants to pull up away from the base, and almost disengages from the drive motor.
I know I could swap the hinge to the right hand side and drive the doors apart and have it work, but everything I see has the hinge on the left side. (feels weird looking down the hinge on the right side
)
