It'd really help a lot if the same kinds of visible magnitude selection and effects that are available for stars and planetary bodies could be made available for Deep Space Objects.
The Quasar Addon that I just created could be made to run quite a bit faster, I suspect, if there were some way to select how many of them are rendered. Drawing 16K points is frustratingly sloooow.
