Hi guys,
I am getting some type of very slight flaring in some of my images and wanting to try and isolate what it may be.
I am using a 12.5" f/5 scope with a Canon 400D.
The scope and secondary cage are seen here:

Essentially I am getting a 5th spike in some of my images but only on a couple of stars and not across what appears to be the entire field.
I am wondering if this is simply reflection from stray light?
I have checked the secondary and the only suspect is a twin set of small screws at the bottom end of the secondary.
I anyone has experienced the same can you share your thoughts.
Latest shot taken with this scope that the attached crop was taken from here:

Thanks in advance.
