Another clear night and I set up three cameras. Two to record firefly trails, and the other to record the nighttime sky for star trails. I still need to do some testing, but it seems that the Nikon sensors do a better job with low light images (less sensor noise). And among the Nikon sensors, the D810a camera does better with exposures over 30 seconds. In addition to the star trails, I also did a time-lapse video of the night sky.
It rained early in the evening, and then again early in the morning so I wasn’t able to leave the cameras out as long. I also reduced the shutter time to 30 seconds on the Fuji X-H1 camera due to sensor noise. I am wondering if the issue with the sensor noise is the temperature outside?
Firefly trails. I added long exposure noise reduction to the Fuji X-H1 camera for the 120 second exposures. It helps, but reduces the number of images that can be taken by half. Bottom line, the Nikon D810a camera does a better job for long exposures.
