Very good condition with minor signs of wear, see pics. Glass is pristine.
William Optics 0.8X adjustable reducer Flat 6AIII - it can be used with the WO GT71, GT81, Z81, FLT91 & Z103 as well as other refractors with similar specs.
Since the back focus is adjustable, getting a flat field with pinpoint stars is much easier than using spacers.
