New Skywatcher 200p Secondary Problem?

[midjam]

I bought a Skywatcher 200p from FLO at the beginning of this month and have just noticed that there is a small piece of the secondary mirror missing. The glass it's self is not damaged it just looks like it was not completely coated when made.

It's about 1-2mm in from the side and about 25mm from top to bottom, you can only just see it through the focuser but, it is visible.

Should I be worried about this, is it pretty common?

This effect is often caused by the way the diagonal is supported whist aluminising. The missing coating will be outside the area in use and will have no affect on the performance.

Secondary's are oversize anyway so it will have no effect.

I had the same on my 200p, on my 250px I have it on both the top and bottom of the secondary. Makes no difference to the views so take no notice of it.
