I have the same solsrscope and had exactly same manual tracking issues. Problem is the sun is 93 million miles sway and the earth does not have to move much at all ( a few seconds only) for the sun to drift off view. I started using my computerised go to mount for much better results. yes more money and I bought also a dovetail mount from online supplier "Agnea" specofically for lunt ( 60 dollar). came with screws and all. works a treat to mount lunt on go to! if you do not align the mount with something like Startracker, you will of course always and often have to realign the sun in the viewing field ( I mean....often) So tracking is definitely a lot less stressful. The issue with concentric rings, still looking into this myself. Think it has to do with lack of focus and finding the correct extension tube length to ensure image from solarscope remains focused on the image sensor of the camera. Maybe someone else can help us with that. As you know, never remove any filters from ypur solarscope or you will damage your eyes, equipment or start a fire
