Hello Albert, and welcome aboard! 8)
I'm with Jon on this one...
I have probably used my color filters a couple of times since I've had them (4-5 years?) and to tell you the truth, I enjoy viewing the planets in their TRUE color, even though the color filters might help you "find" specific features in the planets, but so far I have not had a NEED for them...
On the other hand, I find that having a Lumicon UHC (or Orion Ultrablock), and a Lumicon OIII filter is a must for getting the most out of Nebulas, specially if you live in Light Polluted areas...
Specific nebulas, like The HorseHead, would need an H-Beta filter too...
Clear skies!
