4 alan bolts in dovetail plate- Skywatcher explorer 150p

[Swoop1]

When I built the scope up yesterday, I had 4 alan bolts in the dovetail plate, 2 at each end near the mounting bolts. There were no holes in the mounting rings for these bolts to thread into. What is their purpose?

Thanks.

Can you send pictures as I can't get it in my head.

I have no idea for definite but, in the past I have used mine to adjust the position of the scope very slightly for correcting cone error. I also wondered if they might be there to stop the dovetail slipping through the saddle on your mount if it came slightly loose....

Be interesting to see what the actual reasons are! :-)

To correct orthogonal errors if you can be bothered.

They are there to adjust the alignment of the scope to the mount - cone error.  You screw in four screws and these push against the ring - you then tighten up the center bolt to lock it in position
