Subject: [Baader-Planetarium] Semi-APO vs Fringe Killer + MSG filters





I have a Celestron NexStar 102SLT (4 inch f/6.5 achromatic). I am considering
getting the Baader Fringe Killer filter to get rid of chromatic aberration.
Since almost all my viewing is in suburban locations with lots of sky glow, I am
considering the Moon and Sky Glow filter as well. Here is my question: what
would be the advantages/disadvantages of getting these two filters, versus
getting the Semi-APO? I realize that the Semi-APO would be slightly cheaper, but
are there other factors I should consider. Any suggestions would be very much
appriciated.
