not sure what happened there, is it some kind of reflection in the lens ?

It does look like lens flare, and would be more likely if the coatings are greenish coloured.

Yep, lens flare or a Klingon warbird coming out of cloaking

Steven, check your collimation and make sure your reducer is seated in the focuser properly ( definitely Borg)
