I've trialed most of the "bits" you've got...
IMHO the one to hold onto is the SM40 and BF10.
The SM40 can be mounted on a suitable refractor (up to 1000mm focal length) and will out perform any of the Lumicon bits you have.
There's no benefit it trying to add the Lumicon Ha filters to the SM40 - doesn't work - sorry.
Sell the bit's and try to find either another SM40 for double stacking or move up to a SM60.....keep the BF10 - they are VERY difficult to replace.
