Pleiades is a Mess - Part 2: Lens Flare or Space Pizza?

Using the same data I outlined in my previous post, there are two large, perfectly circular, what I am guessing are lens flares right in the middle of the frame.  I found a similar photograph of M45 online taken with the same telescope and camera that I am using, and that image had the same disks in the same place.

Any advice for reducing this effect?

    On the subsequent attempt, I ended up using Photoshop to deal with the lens flare circles.  I was unable to figure it out in PI

    This ghosting is typically caused by internal reflections between the filter and the ccd window (or surface). It can also be caused by a corrector lens (or reducer) and sensor. 

    Coming soon will be a solution to this issue that will not require Photoshop. 
    I cannot tell you more now, but look for announcements from me and others in the near future.
