You can't use the filters without the spacers. I think the Apogee filter wheel is about the only one I am aware of that can take the thinner filters without the spacer with a special plastic washers and its recessed screw.
I still prefer the Astrodons as they are parfocal exactly on my CDK17, they are 1:1:1 ratio and they have even less reflections than the Baader and no colour bias towards the red. The matching of the filters to the type of sensor and its different colour sensitivities seems to be a real advantage.
ps. I blackened the edges of all my filters with a texta.

A quick look at OPT shows more than a $100 difference in the filter price
Astrodon E series 50mm square unmounted Gen II LRGB set: $1200
Astronomik Type2 50mm square unmounted LRGB set: $699.95
Lot to consider there when all one needs to do is tweek your colour balance in Photoshop...? Or am I missing something?
