completed by: Cezar Mocan
mentors: Akarsh Simha, Victor Carbune
Description: The observing list code (observinglist.cpp) in KStars currently has a lot of duplicate code that can be removed. The aim of this is to remove all possible code duplication in observinglist.cpp.
This will require basic knowledge of C++ and ability to adapt to an unfamiliar API (if you're not familiar with Qt).
Outcome: Cleaner code in observinglist.cpp
