1. No.Similar to the parallax, the apparent positionof a star in the sky is slightly shifted depending on the velocity (value and direction) of the Earth relative to that star. Different to the parallax, there is no similar phenomenon that could be attributed to the rotation of the Earth. No telescope on the Earth would be able to accurately locate any astronomical object, if it would not correct for this effect.
2. the light that travels through the glass takes a longer time to move from one point to another. You can actually see this happening with "refraction." Whenever you see light bending when entering a material like glass or water, this is a result of the light slowing down as it enters.
Hope this helps.
