Up and shooting again!
Wondering about the voltage regulator though, it was not working when i first tried it today. I metered it and it showed zero voltage, brought it upstairs to the workshop and it started metering at 7.2v.
Ill have to keep an eye on it. In the meantime, i started a new routine. 1000 images, 15 minutes apart, 26 inches of movement on the rail. Using a Nikon 50 f/1.4 lens
This shoot will last 10 days 10 hours.
