Hi Glen its an Orion XY giuder, as for observing Sirius's pup I am not into splitting doubles and rarely look at stars through this scope, The night I took the diffraction photos I was looking through the viewfinder of a camera and didnt pay any attention to the pup. Next time I take it out I will make a point of looking for it.
Regards,
Hugh

Re Sirius; have you viewed the pup with the scope?
