3.5/4nm half width (to harmonize exposure time of H-alpha with O-III / S-II), recommended for extremely fast optical systems from f/3.4 to f/1.8
Specially designed for filter requirements of highly opened optics, such as the Celestron RASA astrograph
Enables high contrast even with the strongest light pollution to minimize the size of stars and make nebula details accessible which is useful under a Bortle 9/8/7/(6) sky
Reflex-Blocker hard-coated and optically polished, with Life-Coat sealed coating edges
Blackened edges all around, with a filter front indicator in the form of a black outer edge on the front
Optimized for CMOS sensor cameras and suitable for CCD sensors
FWHM on each filter category is carefully designed to allow for 1:1:1 exposures, matched for typical CMOS quantum efficiency and s/n ratio
Identical filter thickness to existing standards, with attention given to parfocality in the design

Q: 4. Does the ECC require any functionality from the host motherboard?
A: Not all motherboards are made to support ECC RAM. However, ECC RAM will work in a non-ECC motherboard… as long as it is unbuffered. If the CPU or motherboard doesn't support ECC, the board will recognize it as non-ECC RAM and continue to work as normal.
Q: 5. Can I use this Canon 135mm lens on my Sony a7rii body ? What is the best lens adapter/converter to use with it,, that will relay info and not degrade picture quality?
A: The ZEISS Milvus ZE lenses were designed for cameras using the EF mount. The lens can be adapted to cameras with a shorter flange focal distance via 3rd party adapters. These do nothing more than position the lens to the proper distance from the sensor so the lens focuses at infinity. There is no degradation in image quality when using adapters of this type, since there are no additional optics involved. Since the Milvus ZE lens uses and electronic aperture, you will need a 3rd party adapter that allows control of the aperture via the camera body.
Q: 6. Will this work on the Asus Rog Zenith II Extreme Alpha?
A: Yes, this will work on the motherboard. There are 4 PCIe 4.0 x16.
Q: 7. What would be a better option for portraiture, This Lense of the canon 35mm 1.4 ii? (Ps I already own a 85mm)
A: When used with a full-frame camera, a 35mm focal length is a modest wide-angle lens and is well suited for environmental or group portraits. When the same lens is used on a camera with an APS-C sensor, then it behaves like a 'normal' focal length and is suited for head-and-shoulder portraits.
Q: 8. When used on A7Rii with adapter, does it provide focus confirmation? Thanks
A: I'm using my Zeiss manual focus lenses on an a7R iii and find the focus peaking assist on the camera indispensable to sharp, sharp...sharp images!
