Meade 2" mirror diagonal for standard SCT threads. Caps included but no 1.25" adapter. Mirror's in excellent condition. There is a scratch on the outside of the eyepiece holder. The eyepiece holder was out of spec and had to be removed and sanded inside in order for all of my 2" eyepieces to fit. Problem solved, but that's the reason for the low price. Again, the mirror is in excellent condition and appears to be perfectly collimated.
I bought it used to check something out, but I don't need it anymore.
