The OIII-CCD Filter is versatile, catering to imaging OIII nebulas from both light-polluted and dark observation sites, significantly enhancing contrast between objects emitting at 501nm and the background.

Mount Material: Aluminium

Useful for Photographs: Yes

The OWB (Original White Balance) filter effectively adjusts the spectrum of a converted DSLR camera, enabling it to be used for terrestrial photography without constraints.

Transmission: 95%

These filters are excellent for capturing detailed views of the moon and planets, particularly Mars, when used with telescopes of 6" (150mm) aperture or larger.

These filters are tailor-made for capturing the moon and planets, particularly Mars, using telescopes with apertures of 6" (150mm) or larger.

In contrast to filters designed solely for visual observation, photographic CCD filters come equipped with built-in IR-blocking, effectively mitigating optical issues arising from infrared radiation.

Using the Astronomik UHC filter enhances your viewing experience, allowing you to perceive more stars and finer details in deep-sky objects compared to filters offered by other manufacturers.

Utilizing your Astronomik UHC filter promises enhanced star visibility and finer details in deep-sky objects compared to filters from other manufacturers.

Please note: While in principle, all camera lenses, including Canon EF lenses and those from third-party manufacturers like Sigma, Tamron, Tokina, Walimex, etc., can be used with the Clip-Filter, it's important to highlight that Clip-Filters are NOT compatible with Canon EF-S lenses!

You'll find great satisfaction in using your Astronomik UHC filter as it enhances the visibility of stars and details in deep-sky objects far more than filters from other manufacturers.

An improvement over its predecessor, the Atik EFW2.2 boasts a new mechanical indexing system for filter positioning, ensuring consistent alignment for flat field framing. This precision is crucial for maintaining uniform optical characteristics across flat field frames, crucial for accurate dust removal and handling.

This neodymium filter serves as a selective contrast enhancer, crafted especially for reflecting telescopes. It effectively blocks specific regions in the visible spectrum, particularly targeting street lamp lighting and sky-glow caused by scattered light, alleviating the irritation caused by these sources.

Witness the intricate details of lunar craters and planetary landscapes with enhanced clarity!

Named after their discoverer, these two emission lines, known as Swan bands, prominently feature in a comet's gas tail spectrum in the visible range. By permitting only the light from these carbon bands to pass through, the filter effectively blocks stray light, akin to a nebula filter in deep-sky observation. 

The SII filter: A narrowband S-II 7nm filter, designed for nebula photography, selectively transmits light at a wavelength of 672nm with a bandpass of 3nm.

The H-alpha filter transmits light at a wavelength of 656nm, making it the prime choice for narrowband H-alpha astrophotography. It excels in high-contrast imaging, showcasing intricate details of nebulae even in regions plagued by intense light pollution.

The H-alpha filter operates at a wavelength of 656.3nm, making it the premier choice for narrowband H-alpha astrophotography. It excels in high-contrast imaging, unveiling intricate details of nebulae even in regions with substantial light pollution.

The H-alpha filter operates at a wavelength of 656nm, making it the prime option for narrowband H-alpha astrophotography. It excels in high-contrast imaging, revealing intricate details of nebulae even in regions with substantial light pollution.

The Narrowband series presents line filters with a full width at half maximum of 6.5 nanometers, ideal for optical systems ranging from f/10 to f/3.5 in aperture ratio.

OIII filters exclusively permit light with a wavelength of 501 nanometers to pass through. This wavelength corresponds to the spectrum lines of doubly ionized oxygen emitted by planetary nebulae and certain emission nebulae. By selectively allowing this specific light to pass, these filters enhance contrast and reveal faint nebulae while blocking out other wavelengths.

OIII filters exclusively permit light with a wavelength of 501 nanometers to pass through. This wavelength corresponds to the spectrum lines of doubly ionized oxygen, emitted by planetary nebulae and some emission nebulae. By selectively allowing only this specific light to pass, these filters enhance contrast, making faint nebulae visible for the first time while blocking out other wavelengths.

OIII filters selectively pass light with a wavelength of 501 nanometers, corresponding to the spectrum lines of doubly ionized oxygen. These lines are emitted by planetary nebulae and some emission nebulae, allowing these objects to remain visible while other wavelengths are blocked by the filter. This enhances contrast, revealing faint nebulae that may not be visible otherwise.
