ZWO SII 7nm 1.25" Filter

ZWO 7nm Narrowband Filter Set: Precision Tools for Enhanced Astrophotography Contrast

Transform your astrophotography with the ZWO 7nm Narrowband Filter Set, meticulously designed to accentuate the finest details of emission and planetary nebulae. These premium filters excel in isolating specific wavelengths emitted by ionized elements within nebulae, providing astrophotographers with the tools to capture the cosmos like never before.

Key Features:
Selective Wavelength Transmission: Each filter in the set is finely tuned to a 7nm bandpass, optimizing the visibility of H-alpha, OIII, and SII emissions.
Superior Contrast: By blocking 98% of unwanted light, these filters significantly improve the signal-to-noise ratio, ensuring that nebulae stand out against the background of space.
Versatile Use: Ideal for both imaging and visual observations, especially the OIII filter that corresponds with the peak sensitivity of the human eye.

Technical Specifications:
Bandpass Width: Narrow 7nm for precise emission line capture.
Filter Sizes: 1.25" mounted, compatible with most filter wheels and holders.
Design: The latest series with enhanced coatings to reduce internal reflections.

Astrophotography Impact:
True Color Rendition: Capable of producing stunning false-color images of nebulae by combining three distinct wavelengths.
UV/IR Rejection: These filters inherently block infrared and ultraviolet light, streamlining your setup without the need for additional IR-UV cut filters.     Elevate Your Astrophotography:

With the ZWO 7nm Narrowband Filter Set, dive into the heart of nebulae, revealing the ethereal beauty of the cosmos. Designed for the discerning astrophotographer, these filters are your key to unlocking the full potential of narrowband imaging.
