Oxygen 111 Filter Help Please

Hello all. I have already posted this but I think in the wrong place.. I'm new to all this and its a big learning curve. I have a 10" DOB and a Celestron 80mm Refractor Nexstar GT goto. I recently purchased a Baader O111 Filter to help me see more detail in deep sky objects like nebs. I live in a lit location so I thought this filter may help me.

I was a little dissapointed to find it makes all that I am looking at have a green look as if you were looking through a green filter. Is this normal and part of getting more detail? or are thier different O111 filters that don't give this green colour? I have noticed on this forum people that have use these filters for photo's and don't seem to have a green look about them. I understand that we see different colours than a CMos or CCD see's. I was talking to another guy who told me his O111 filter does not colour the view at all. Have I got the wrong type?

If I look at the filter it has a mirror finish to it until you hold it up to the light. Then you can see the green colour like looking through an old green bottle..


Cheers
Mardy
