Overview

Discover the Unmatched Brilliance of the Chroma OIII Filter!

If you’re looking to dramatically increase the level of detail within your narrowband images, this Chroma 8 nm OIII filter is the perfect solution! By cutting through other wavelengths to increase contrast on this specific element, enjoy collecting rich OIII data on a wide variety of emission nebulae. Also, this Chroma narrowband filter is effective in reducing the effects of light pollution as well as Moon glow. Not only is this beneficial for those living in the city, but it helps increase your imaging opportunities. An important component to SHO and HOO imaging, having an OIII filter of this caliber under your belt will help you create vivid, colorful astrophotos.

The team at Chroma Technology fully understands the ins and outs of filter development, and has crafted this filter with high quality glass and superior coatings to ensure maximum performance. These sputtered hard coatings on both surfaces eliminate ghosting and ensure maximum light transmission to your camera sensor, and are extremely resilient to environmental impacts such as humidity and temperature shifts. With a 8 nm bandwidth, this Chroma narrowband filter provides intense contrast on OIII light within the Veil Nebula, Thor’s Helmet Nebula, the Tadpoles Nebula, and plenty more! Mounted within a 2” threaded filter cell, this Chroma OIII filter seamlessly joins into your imaging train.

A Professional Grade Astrophotography Filter of the Highest Quality

Let’s Check out the Stats!

What exactly makes one filter better than another? How can I tell which filter will be best for my needs? To understand how well a filter performs, manufacturers provide what is called a transmission chart along with their filters. These charts give insight into the wavelengths allowed through, the bandpass, as well as the transmission percentage. It may be a bit confusing at first glance, but no need to worry, we have you covered! Our team of gear experts have crafted a comprehensive How to Read a Filter Transmission Chart guide to help you better understand the capabilities of any filters you may be interested in. With this article, you’ll be readily equipped with the knowledge needed to make a well informed, data-driven decision based on your specific needs.

8 nm OIII Bandpass
OIII is a one of the most prominent emissions within emission nebulae, and features a wavelength of 500 nm. Isolation of this wavelength is crucial in discerning intricate structure within these celestial objects. Offering an outstanding transmittance of 94.5%, this Chroma OIII filter allows copious amounts of OIII data through to your sensor. Pair this with the narrow bandwidth of 8 nm and be amazed by the sharp contrast seen within your images! With its light blocking nature, light pollution from urban settings as well as the Moon are significantly less impactful on the quality of your astroimages. Combine the captured OIII data with H-alpha and SII for a vibrant Hubble Palette image, or try out the HOO palette and create a stunning bi-color astrophoto!

Effortless Integration
Compatible with most filter wheels and filter drawers, seamlessly join this Chroma 8nm OIII filter to almost any set up! A wide variety of user-supplied filter holders, such as the ZWO 7 Position Electronic Filter Wheel, ZWO Gen 2 M42 x 0.75 Filter Drawer, and the QHY CFW3 Large Color Filter Wheel are great choices to house this Chroma filter within. The 2” size is wonderful for use full frame cameras, providing sharp detail to the edges of the frame. The male threads on this mounted filter feature a height of 1.75 mm, while the filter cell height excluding these threads is 5.25 mm. The total filter height is 7 mm.

Excellence in Every Detail
Ensuring performance for years to come, Chroma has crafted this OIII filter with premium hard coatings. These coatings are applied using a technique called reactive magnetron sputtering, and offer superb resilience to humidity changes and extreme temperature fluctuations. Not only this, but these hard coatings help preserve spectral accuracy in the central wavelength (CWL). Both sides of this filter are fully coated, with anti-reflective coatings found on the rear surface to prevent image distortions and image ghosting. Chroma astronomy filters utilize 3.0 mm thick single substrates of the highest quality glass. This use of a single substrate eliminates the need for lamination, in-turn improving the filter’s overall performance and durability.
