Expert Help Needed - What is this?

Hi All,

While setting up for a polar align last night, I was using Canopus as a calibration star and noticed a very odd object on a short exposure while manually trying to slew to the star for alignment. Once i'd finished a two-star align (with 3 calib stars) i went looking for it again and took some longer exposures.

I'm trying to figure out what it is and would love some help from you all!! At a first glance I thought is was a deep sky object (thus posting here...) however after some examination i'm thinking the object is too 'regular' in geometry and inconsistent while shooting it in different parts of the frame, that perhaps its some reflection issue in my OTA? or wires from camera at front of OTA?

Any thoughts welcome????

Thanks,
