sirius MV 1 vs. Orion V-block

Hello all, I own a meade AR 5, the chromatic aberration is not to bad but I feel I could be losing a little contrast on certain bright objects. I was wondering if these filters are worth the $60 bucks and which one do you think is better. Also I saw a new sirius MV 20? Could someone inform what the difference is between the mv 1 and mv 20.

Thanks,
Tom

I have tried both Sirius MV20 and Baader Fringe Killer

They both are very very good. However, if you are planning to stick the filter on a diagonal then you will have to go for the Fringe killer because it's the only filter that doesn't cause "ghosting"

In the case of Sirius and other brands you have to thread the filter directly on eyepiece to avoid the ghosting. Imagine you have to change eyepieces all the time, this can be a real pain in the a$$.
