Filter threads directly into the 2 inch barrel of your telescope eyepiece. 90% transmission means the filter also blocks the light from mercury and sodium vapour lamps. Standard M48x0.75 thread interface. The thickness of the filter can affect wavelength and dispersion of the filter. The filter can use with filter drawer and electronic camera. The Narrowband filter is designed for nebula observation.
