Looks like some sort of light leak.

Did you use DSLR camera to take the shot and if so - did you cover the viewfinder window?

There is little plastic cap, usually sitting on strap - that fits over viewfinder and serves this purpose to block stray light.

DSLR viewfinder leakage is usually at the top of a landscape frame.

Post an image of the image train.

Scope -> adapter -> field_flattener -> extension_tube -> camera

That is why it's called the train

Hi

There's quite a bit of chromatism emphasising any reflection from the lens surfaces, shown mostly in the red, less so in green and almost flat in blue. Over full frame, tilt is critical, especially in a lens with 17 elements (34 glass surfaces).

If you have another eos adapter e.g. from another Tamron, I'd try that first.

Along with a shorter focal length at say f8,  I'm sure a decent vset of calibration frames would go a long way to help in processing.

Or, as you have what looks like very good data anyway, just go ahead. I'd put good money on a stack of those images making for a stunning shot.

Cheers and HTH

Thanks for your help I appreciate it

i believe that the reflection in the center is a ir light inside the lens that’s what others have told me and with my camera being modified it picks up on it 

and just a question what is tilt

Be sure to turn of IS and AF.

In this case, probably because the lens or one of its elements are not held orthogonally to the camera's sensor.
