How to internally mount an ERF?
How to internally mount an ERF?
How do you guys make a filter holder for a sub-aperture internal ERF, since it has to be tilted a bit to prevent reflections? A straight fit, or mounting a holder onto a internal baffle should be easy, but how to tilt it AND keep it firmly in place?

The baffles on my old CR150HD are easy to keep in place even at a tilt. They just jam into the tube.
