UPDATE: I've actually had slight improvement tonight by "rotating" some of the imperfections in the condenser lenses out of frame... if that makes sense. Good luck to anyone else suffering the same problems... the Omega DII is a fantastic piece of equipment!
I had the same thing with my D2 and discovered a pair of glass bubbles in the condenser lenses I rotated them out of sync and got them out of the frame but the best thing I ever did was get an Aristo cold lite
No escaping it!
I must step on fallen leaves
to take this path
