Getting reflections off of Alnitak isn't much cause for complaint as not many scopes don't.
I have seen large expensive RCOS's do the same in images.
As Bert points out there are other causes than the scope for reflections.
Unblackened edges of filters, shiny parts inside the CCD chamber and an aperture mask to the CCD can reduce these. Apogee sent one out to purchasers of their U16M camera after research found it reduced reflections.
