When user input a position like (-34, 23) or (123, -91), Firefly treated it as object name and gave the error message "Could not resolve Object: Enter valid object". It is hard for user to understand exactly what was wrong with the input. In reality it is the position out of range error. Firefly should provide better error message for situation.

Another issue: "12.3, 23.4" is valid input, but "12.3, 23.4 gal" is not. And we have an example for the latter in the input pane.

input "18.0, -23.0"  has been interpreted into "18.0, -23.0  Equ J2000 ". but the latter is invalid

input "12 34 56.89 -23 45 16.56"  has been interpreted into 12h00m00.00s, -23d00m00.0s  Equ J2000
