This may have been discussed several years ago in the former Yahoo groups: when should one change location in the AN, esp. if locations may be close to each other. For example, do I need to change locations if they are 50 miles (80km) apart (40.2N 75.5E versus 40.7N 75.9W)?
How about ~228 miles (367km) 41.7N 77.7W from above two sites

Thanks for the post.

Argo Navis takes into account the correction for parallax error depending on where you are standing on Earth whilst observing solar system objects.

For artificial satellites in low earth-orbit you should use a reasonably accurate set of latitude longitude coordinates to compute where the satellite will appear above your local horizon.

For the Moon, a distance between observing sites of 228 miles would make a negligible difference given it is a quarter of a million miles to the Moon.

For users with exact polar aligned mounts who also use TPAS, reasonably accurate latitude and longitude can help refine the polar misalignment errors.
