The Object Selection module provides a screen for easy management, selection, and filtering of different object databases (Figure 1).

Select/Update button either takes you to the Select Conditions screen where you set object catalogs to search in and filter criteria (Select button), or performs a search in the selected catalogs based on filter criteria (Update button). After the search the list of objects from the current database complying with the filter criteria is displayed, and Update button turns into Select button. While the search is running the Stop button appears. Press it to stop the current search (e.g. if it takes too long). All objects found till the Stop button press will be displayed.

Select button turns into Update button if some of the search criteria changes (e.g. location, observation time range, etc).

Constellation button allows to filter search results by constellation.

Touching an object in the list takes to the Star Chart with a touched object in the center. Context menu provides a wide range of operations from forming Observations Lists to note taking.

The list has the following columns: NAME, CON (constellation), TYPE, MAG (magnitude) and DIM (dimension). Touching column name sorts the list by that parameter. Second touch reverses the sort order.


Context Menu


The program provides two simple gestures that could be called throughout the application for calling Menu and returning to the previous window.
