Filters for use with a dslr

[jazzin]

I shoot with a dslr camera and really want to get me a dual narrowband filter but am wondering if I should get the dslr clip in filter or the 2" thread on filter? Or does it even make a difference?

Clip in filters tend to be more expensive and will hamstring you to that particular format of camera.

In my experience, a 2" equivalent filter will cost less and is far more ubiquitous in AP circles.
