SAFETY FIRST: Observing the Sun without the proper protection may result in serious personal injury, including permanent eye damage and blindness, and/or damage to equipment. Never point an optic at the sun without an approved solar filter on the front of the optic. For direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder, ensure your filter is ISO 12312-2 (also written as ISO 12312-2:2015) certified. Never use photographic neutral density filters for direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder.

When imaging the sun in monochromatic light, such as H-alpha, a common issue is the appearance of lines on the resulting image caused by light reflection inside the CCD camera's imaging sensor. Daystar Filters' C-mount equipped Interference Eliminator tilts the camera off-normal by up to 5° while keeping the center of the image sensor stationary, so that focus, framing, and vignetting are not affected. This tilt changes the angle of incidence and optical path lengths inside the image sensor, mitigating or eliminating the interference. These lines, called interference fringes, interference patterns, or Newton's Rings, are caused in long focal ratio applications, by nearly parallel light being internally reflected inside the image sensor or camera, causing an addition or subtraction of the light waves. The Interference Eliminator can hold a camera rig up to 7.7 lb and is recommended for long focal ratios, f/30 ideally, as seen in most Daystar filters.

Interference Eliminator (C-Mount) is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from It does what it is meant to do. If you are into solar imaging, you will need this accessory to get rid of newton's rings. By slightly shifting position of your camera you can eliminate the light and dark interference bands cause by light. You can see an example of solar images without the rings in my review of celestron 132m camera. where I posted 2 solar images taken with this accessory being used. I cannot solar image without it.
