I would be really grateful if someone could help me with the Catseye Infinity XLK Autocollimator (duel pupil).
I'm using it to collimate my f4 ts optics Newtonian.
The problem I have is that I haven't purchased the hotspot centre ring so I'm using the standard donut on the primary and this is then hard to compare to the pictures in the instructions.
I think I have got all four circles lined up however I have a second black dot that is confusing me? Is this simply the reflection of the second pupil hole and so nothing to worry about or should I be trying to line up both the black dots? Apologies if this is a silly question!!!
I have tried to take a picture to show the black dot, hopefully you can see it to the left of the ring, this is taken through the central pupil.
