About this print
A bahtinov focus mask sized for the ZWO Seestar S50: place it over the front and the central diffraction spike tells you, to a hair, whether you're in focus — the classic, foolproof focusing aid used on every serious astro scope. A 5.0★ design. Printed in PLA. Fits the Seestar S50 (ZWO); this is an independent accessory, not made by or endorsed by ZWO.
