Thanks all . Dennis not too much changing all I do is swap the Lunt WL wedge for the CaK wedge. Focus is close and I just swap the camera over with minimal setting change.The Lunt 100 is identical in aperture and FL to the 102ED so they all go together well and give a good comparison at a standard aperture.
Trevor if you look closely you'll see that the top right Ha and centre WL pic are slightly better in regards to seeing. I tried to process them all almost identically.
