This is an SBIG 8300 with the Kodak chip, nothing to do with Panasonic. It does NOT have the issue when the LP filter is removed (well nowhere near as evident). Plus it is not just Alnitak as I showed with ETA Carina (see red ghosting top right and mid bottom).

I think there is bouncing light between cover plate and Baader filter
