Four photos of the September 28, 2015 lunar eclipse taken with a Nikon D750 and 800 mm f/5.6 Nikkor ED telephoto. The last three exposures were 2.5 seconds. A 2.5 second unguided exposure means that the moon shifted 2% of its angular diameter while the shutter was open. This resulted in a linear blur in the last three images.
