Interesting topic here.
For mars I've been using GSO # 96-0.6/96-0.9 & or a baader contrast booster.
They tell me the thing for mars is the IR cut filter, but not sure as to the advantages of this. True or false guys....better mars images with this IR cut or not?
Dave, does the toucam adapter has an internal thread? (I gather it does)
My baader screws onto any eyepiece, not sure if that helps determining weather or not a baader filter will fit your adapter or not..EDIT: sorry just realized you meant can U couple those 2 filters rather than if the baader fits the adapter or not.
