I have a Saxon 90mm o.d. x1250mm focal length maksutov on what i think is a AZ3 mount. Very light setup, can be picked up in one hand. Sharp optics, good for day or night sky viewing. Optical tube comes with 1.25 inch prism diagonal ( made in Japan ), and a red dot finder. Sorry no eyepieces. I placed a handle on the mount for easy pointing. Asking $220.00. Postage extra. Negotiable
