ZWO S-II Filter 7 nm - 1.25" mounted

The narrowband nebula filter has a definite pass band around 672 nm. This is the line in which many planetary nebulae, emission nebulae and supernova remnants shine. Transmission in this range is 90%. The filter is the optimal choice for astrophotography. The contrast of nebulae is significantly increased.

Besides an L-RGB filter set, you can also get the H-Alpha and O-III filters from ZWO, with which false colour images and narrow band nebula images are possible. The filters are parfocal among each other.
