ZWO Narrowband Filter Set for Astrophotography:
Narrowband nebula filters significantly increase the contrast of an object and eliminate light pollution. Due to the bandwidth of 7nm, images are displayed with extremely sharp contrast, even from light polluted cities. ZWO filters are homofocal with each other. The filter set consists of:
ZWO H-Alpha Filter 7nm:
This narrowband nebula filter has a definite pass band around 656 nm. This is the line in which H-II objects (hydrogen nebulae). Transmission in this range is 80%. The filter is the optimal choice for astrophotography as the contrast of nebulae is significantly increased.
ZWO O-III Filter 7nm:
This narrowband nebula filter has a definite pass band around 500 nm. This is the line in which many planetary nebulae light. Transmission in this range is 80%. The filter is the optimal choice for astrophotography as the contrast of the nebulae is significantly increased. This filter is also suitable for visual observation.
ZWO S-II Filter 7nm:
The narrowband nebula filter has a definite pass band around 672 nm and like the O-III this is perfect for many planetary nebulae as well as emission nebulae and supernova remnants shine. Transmission in this range is 80%.
Specs:
- Type: Nebula filter, interference filter
- Size: 2" mounted in a low-profile filter cell
