Wow, that is cool looking. Mine does get the secondaries burning sometimes, but never like that. I am starting to think that my wood is probably a big factor is the lackluster performance. The wood that I am burning now is supposed to be seasoned, but I took a moisture reading on it and it was 15% on the outside and nearly 30% on a freshly split face. I don't hear or see any moisture burning off of the wood, but I guess it is there. I guess it is time to find another source of wood for this year. Next year I should be able to start burning my own seasoned wood.
