Just make sure you are comparing the latest generations before making this decision ...in light of this the price difference is indeed a factor
Certainly your results speak for themselves Mike.

I liked the Astronomiks and I am sure the new anti reflection would be an improvement (although I did not have reflection issues particularly with the older set). They are good value but you have to add in the cost of the spacers when comparing them. In my case Gert wanted AUD$100 for them. I don't know what he is charging now. 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.

Greg.
