The top picture of the SCT wedge looks just the one I have on my 8"Meade LX100. I have had it for 12 years now and have used a camera many times on scope. It is a nice casting and seems beefy enough with those strengthening fillets along the sides. It says Made in USA so maybe that's why I have no problems, but think 12" might be stretching things a bit - it wouldn't fit on, would it?.
