I frequently run sequences that contain up to 40 unique variable stars. It isn’t something you’d want to do by hand.
Currently I manipulate a CSV file from the AAVSO’s VSX to create a text file to Import with Starry Night. It sure would be a whole lot easier to have a new File/Import that would do a CSV or txt file with the target name, RA, and Dec on the same line separated by tabs (for the text file) or commas (for the CSV).
Something like that would make building sequences with a large number of targets a whole lot easier.
