Astronomik Filters T2 CLS CCD filter (43795)
The Astronomik CLS-CCD Filter is a highly effective tool for astrophotography, particularly in light-polluted environments. Designed for DSLR cameras modified for astronomical use, it enhances the contrast between deep-sky objects and the background by blocking artificial light sources like sodium and mercury vapor lamps while allowing essential emission lines to pass. Its optimized design ensures minimal dimming of stars and excellent performance for capturing nebulae, galaxies, and star clusters.

Description
- Enhanced Contrast: Improves visibility of deep-sky objects by blocking unwanted light while transmitting useful wavelengths.
- Wide Transmission Curve: Allows more light to pass compared to UHC filters, reducing star dimming.
- Compatibility: Suitable for DSLR, CCD, and black-and-white film photography, as well as telescopes or photo lenses with apertures of f/3 and above.
- IR Blocking: Includes an IR-blocking layer, making it ideal for use with DSLRs and webcams lacking integrated IR filters.
- Blocks emission lines from artificial light sources (e.g., streetlights) and airglow.
- Passes critical emission lines like H-beta (486 nm), OIII (496 nm & 501 nm), and H-alpha (656 nm).
- Suitable for astrophotography under urban or suburban skies with significant light pollution.
- Connection: T2 (M42 x 0.75) thread.
- Coating: Multi-layered optical system resistant to scratches, humidity, and aging.
- Transmission Efficiency:
- 95% at H-beta (486 nm) and OIII (496 & 501 nm).
- 97% at H-alpha (656 nm).
- Frame Type: T2 (M42 x 0.75).
- Build Type: Broadband filter.
- Visual Use: Not suitable for direct observation.
