One line summary:
Star trail images show major inconsistencies with the present model of the rotating globe and position of Polaris.
Description:
Star trail images are typically taken by the photographer affixing the camera firmly on the ground using long exposure, manual mode. In this manner the relative star motion (based on rotation of the earth) can be captured in a single image.
Using this concept, multiple star trail images have been taken at various latitudes on earth. This figure (http://imgur.com/a/nSPWi) shows some representative images of star trails taken from places in the northern hemisphere. It can be seen that all of the stars seem to be rotating about a central point that appears stationary. The rest of this note will elucidate why such images are contradicted by the globe earth rotation model.
According to present day astronomy, Polaris is situated roughly on the the earth rotation axis above north pole. So if one were to capture star trail images directly over north pole, Polaris would not have any relative motion to the photographer and every star will appear to revolve around Polaris. This is strictly due to the rotation of the earth. However, if star trail images are captured on any other point on the northern hemisphere, Polaris cannot be stationary since the relative motion with respect to the photographer is not zero anymore. This is clarified mathematically here - (http://imgur.com/a/07yvH)
Conclusion:
We are faced with multiple evidences of star trail images at various points on the northern hemisphere with the clear presence of a stationary star, i.e., the rest of the stars in the sky have an apparent rotation motion about a center point that is stationary. Using the principle of relative motion, these star trail images offer a severe contradiction to the globe earth rotation model. It is pertinent that this model be revisited in light of these observations.
