1.25" 90^ Erecting Diagonal with anti-marring ring

[Star Gazer]

Does anyone now where I can get a 1.25" 90 degree diagonal that gives an upright images and that won't mark my eyepieces; i.e it must have an anti-marring ring?

The closest I have come is 45 degree WO diagonal. But I prefer 90 degree

Thanks

I've got one of these and very good it is too. Well made with brass compression ring and much better optically than the WO etc. 45 degree erect prisms, and in fact good enough for medium power astro use.

I've bought a few things from Astroshop and the service has been excellent each time.
