Good job Wes.
I think the black looking dots on the star fringe may indeed be from oversaturating the blue channel in combination with the field rotation due to the dob mount.
Plus the optical centre of the pic is mid left so that might add to the issue.
Might have to get an equatorial platform!
The use of a coma corrector would be good ... I'm selling one(!) but you might wanna get a upgrade to a Parrcor or Baader MPCC mark 2 or better.
The dslr isnt that sensitive to blue so there shouldnt be so much in a pic. The background should be a lighter black....?
