What is generating the concentric circles? Is that an attachment on the front of the laser? If so, you should remove this for the barlowed laser primary adjustment.

I've attached an image of my Glatter barlowed laser view of the primary. In my case I have a catseye hotspot rather than a ring on the primary so the shadow shape is different however you can see how the barlow should smear out the laser light to create the shadow centered on the hole in the tublug.
Mmmm - I didn't know that bit came off.... yes, with that removed it looks much better - will post a pic.
