H-alpha Filter: The H-alpha filter allows light with a wavelength of 656nm to pass through. It is considered the best option for narrowband H-alpha astrophotography when aiming for high-contrast images and revealing intricate nebula details, even in areas affected by strong light pollution. OIII Filter: The narrowband O-III 3nm filter is specifically designed for observing nebulae. It allows a narrow 3nm bandwidth of light centered at a wavelength of 500nm, which matches the OIII emission lines, while blocking all other wavelengths. SII Filter: The narrowband S-II 7nm filter transmits light at a wavelength of 672nm with a 3nm bandpass, making it ideal for nebula photography.

These are safe, full aperture solar filters, sometimes called clear aperture filters. They are designed to allow the maximum amount of light into the telescope by making use of the full aperture. This provides the best possible daytime viewing, especially when atmospheric turbulence is minimal. If turbulence is present, a mask can be placed over the end of the filter to effectively reduce the aperture. This premium solar filter features an aluminum cell that is secured and centered on the end of the telescope tube with nylon thumb screws and felt padding.

Astronomik Filters CLS CCD XT Clip Sony alpha 7 (85677)

Astronomik XT filters enable you to capture sharp, beautiful star images right into the corners of the frame, even with extremely wide-angle lenses. With other Astronomik filters, image quality in the corners can be limited at short focal lengths. Although these filters use a glass plate only one millimetre thick, this thickness can cause aberrations with certain wide-angle lenses, stretching stars into lines. Astronomik XT filters are built on an ultra-thin substrate, just 0.3 millimetres thick. This thinness minimizes “star streaks” in the corners.
