C8 black aluminum OTA in very good condition, clean optics and Fastar compatible. I beleive year of manufacture is 2000. It holds collimation perfectly well, and when properly cooled down (something hard to do where I live), the inside and outside of focus images are nearly identical. Ronchi lines appear straight. It is clean and relatively dust free. I've gotten plenty of detail on Mars and deep sky objects are wonderful. Comes with standard visual back and diagonal, along with 6x30 finder and mounting hardware. Selling to finance another project. I'll take money orders, or personal checks from Astromarters with good history.
