Ok thanks guys. All of the ghost lines I've seen have been parallel to the limbs and nothing I saw ran full length, it just seemed to be a couple inches at most, and all definitely appeared to be under the glass from what I could tell. Nothing unsightly, both the Mahaska and the River Raisin I have are gorgeous. The M. is cocobolo with cedar limbs and the RR is a medley of woods with Bocote limbs. As you all say, just me noticing normal things under extremely bright Florida sun.
