I think you just might want to read through these posts!

Whilst you are going to image with the ICX285 it is still a very sensitive chip in blue and you may see similar results to mine using the Sony 694 chip. I would strongly consider looking for a red filter that does not go down as far as 380 nm (the Baader). The Astrodons cut at 400 nm (better, but for me not nearly good enough). Even at 410 nm with a Hutech IDAS filter there is still blue fringing though it is much improved over the Baader without any help. Astronomiks is working on a filter set that will address this very issue with these sorts of cameras on a refractor. I'm sure you don't want to wait, but forewarned is forearmed. Good luck!
