Shipping Calculator
The ZWO Darkening Rings are thin shims that stop light leaks in the space between EFW filter wheels and ZWO imaging gear.
These rings are 88mm wide, which fits the EFW 5 x 2", 7 x 2", 7 x 36mm V1 & 7 x 36mm V2.
They are really thin, less than 0.2mm, so they don't change the back focus distance much. You get four rings in the set.
The ZWO Darkening Ring Set is compatible with the following ZWO Electronic Filter Wheels:
- ZWO 5 Position 2-inch Electronic Filter Wheel
- ZWO 7 Position 2-inch Electronic Filter Wheel
- ZWO EFW 7 Position 36mm Electronic Filter Wheel
