ZWO O-III Filter 7 nm - 36 mm unmounted
The narrowband nebula filter has a definite pass band around 500 nm. This is the line in which many planetary nebulae shine. Transmission in this range is 80%. The filter is the optimal choice for astrophotography. The contrast of nebulae is significantly increased. The filter is also suitable for visual observation.
Besides an L-RGB filter set, you can also get the H-Alpha and S-II filters from ZWO, with which false colour images and narrow band nebula images are possible. The filters are parfocal among each other.
