About the ZenithStar 73 II

The ZenithStar 73 is one of the most popular small imaging refractors ever made — compact, light, and sharp. It's a 73 mm f/5.9 air-spaced APO doublet (430 mm focal length) using Ohara FPL-53 ED glass for excellent colour correction, with William Optics' 2.5" dual-speed rack-and-pinion focuser and signature fit and finish. At 430 mm it frames large emission nebulae, galaxies like M31, and open clusters beautifully, and it rides easily on mid-size mounts and travel setups. The II version has since been superseded by the ZenithStar 73 III, and the gold finish is a sought-after look.

This package is ready to image out of the box: the Flat73A flattener gives flat, round stars across the field, the Optolong L-Pro helps cut through suburban light pollution while keeping natural star colour, and the guide scope with ASI120MM Mini gets you guiding for longer exposures. Everything packs into the William Optics case.
