Using narrowband filters can often result in slightly dimmer images, which can be difficult to resolve to a focus. You can now use this filter to focus perfectly with a bright image and since they are also parfocal, switch to a different narrow band filter without losing the focus.
The Antlia IR Pass 685nm filter is an absorption filter that allows infrared light with wavelengths of more than 685nm to pass through. It nicely complements the Antlia 850nm IR-Pass filter.
The Antlia IR Pass 850nm filter is an absorption filter that allows infrared light with wavelengths of more than 850nm to pass through. It nicely complements the Antlia 685nm IR-Pass filter.
UV-IR cut filter is designed for ultraviolet and infrared wavelength blocking to improve sharpness of the image as most of the optics are designed for the visible spectrum
This very useful addition to the Baader filter range is intended for the luminance channel in astro imaging. Using narrowband filters can often result in slightly dimmer images, which can be difficult to resolve to a focus.

The ZWO Duo-Band Filter is a dual narrowband filter primarily aimed at complementing our range of colour ASI cameras and offers an economical entry into the world of narrowband imaging and can also offer a practical solution to imaging in light polluted urban areas.
Single Astronomik Type 2C Green Filter in 36mm fitting. A superb addition to a monochrome system. Astronomik only deliver the highest quality in regards to coatings and quality.
The Optolong extra Narrowband OIII-CCD 6.5nm filter is designed for nebula observation allowing 6.5nm bandwidth of light centered on a wavelength of 500nm through, which corresponds to OIII emission lines, and reducing the transmission of certain wavelengths of light
