The Solar Continuum Filter is practically a narrow band photosphere filter for solar observation in white light. It provides the highest contrast in the photosphere of the sun.

The Astronomik ProPlanet 642 BP is the lastest addition to the family of Astromik ProPlanet IR-pass filters. The filter thrills because of it´s wide range of applications.

Observing difficult, dim Deep Sky targets like Planetary Nebulae and certain supernovae remnants, such as the Veil Nebula in Cygnus from light poluted environments can be a very tricky business.

The EXPLORE SCIENTIFIC H-Alpha filter uses the characteristic of the so-called emission nebulae. These objects glow in certain colors, the so-called emission lines.

The EXPLORE SCIENTIFIC S-II filter uses the property of the so-called emission nebulae. These objects glow in certain colors, the so-called emission lines.

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

Optolong extra narrowband SII-CCD 6.5nm filter (Sulful II for CCD) is designed for nebula observation allowing 6.5nm bandwidth of light centered on a wavelength of 672nm through, and reducing the transmission of certain wavelengths

This H-alpha Filter is suitable for imaging of Hydrogen nebulas from observation sites with light pollution and from dark sites as well. The FWHm of 12nm is optimized for typical DSLR cameras with CMOS sensors and CCD cameras with a normal/high dark current.

This Astronomik OIII-CCD Filter is suitable for imaging of OIII nebulas from observation sites with light pollution and from dark sites as well.

The L-Pro (L-Professional) filter is designed to improve the visibility of various deepsky objects. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lightings

Baader S-II Narrowband Filter – Precision Grade
6.5 nm FWHM, recommended for optical systems from f/10 to f/3.5. Reflex-Blocker™ hard coated and planeoptically polished

The Astronomik CLS is a budget filter for visual observation, Black & White photography and CCD photographs of nebulae, galaxies and star clusters with astronomical instruments of any size.

The OWB filter would usually not be designated as an "astronomical" filter. The intention is to enable converted DSLR cameras (without inbuilt IR-filter) in order to be used for 'terrestrial' photography.

This SII Filter is suitable for imaging of SII-regions from observation sites with light pollution and from dark sites as well. Contrast is massively increased.

L-eNhance provides an economical and practical solution for amateurs. It is a dual-band pass filter which has been designed for DSLR (digital SLR), color CMOS and CCD cameras.

Baader O-III Narrowband Filter – Precision Grade
6.5 nm FWHM, recommended for optical systems from f/10 to f/3.5. Reflex-Blocker™ hard coated and planeoptically polished
