ZWO has developed a new version of their ASI 2" filter drawer called the New ZWO-FD-M42 and New ZWO-FD-M54. These filter drawers feature an added anti-light leakage design to effectively solve the problem of light leakage during long-exposure imaging. Additionally, they utilize magnets to provide a more secure attachment, making installation and removal easier and more convenient. The filter drawer is equipped with locking screws, and the locking function can be adjusted to eliminate any gaps, providing double insurance for the filter's stability.
