Observation Planning Tool

1. Select time frame Selecting any date range within a 30-day period from today enables object filtering with pre-computed data (faster ephemerides calculation). Selecting a date range outside of this 30-day period (including days in the past) will not use pre-computed data for the filtering stage. However, object selection by type and database will be still available.
