Use the transparent horizon when you wait for Mercury to raise on the morning. - To search in a catalog build with the Catgen tool (Hipparcos is in this case) you must search exactly for what the ID field is set in Catgen, do not add the catalog name if it is not include in the original catalog data. - The Gliese catalog use another format better suited for small catalog.
