Baader U-Filter for Venus and UV imaging
Transmission peak approx. 80% at 350nm, bandwidth 60nm (320-380nm), completely blocking the entire spectral range from 200nm to 1120nm

Astrodon introduces a breakthrough in UV filters for CCD imaging. A durable, hard-coated UV filter of the highest quality having the best transmission available.

Baader O-III Ultra-Narrowband Filter – Premium Grade. 4nm FWHM recommended for optical systems from f/10 to f/3.5. For highest contrast even at strongest light pollution, minimizes star size, emphasizes finest nebula detail

Baader S-II Ultra-Narrowband Filter – Premium Grade. 4nm FWHM recommended for optical systems from f/10 to f/3.5. For highest contrast even at strongest light pollution.

Baader S-II f/2 Ultra-Highspeed Filter – Premium Grade. 4nm FWHM, recommended for extremely fast optical systems from f/3.4 to f/1.8. Specially designed for the special filter requirements.

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.

Baader O-III f/2 Ultra-Highspeed Filter – Premium Grade. 4nm FWHM, recommended for extremely. Specially designed for the special filter requirements when used with fast optics like the Celestron RASA astrographs

Increased contrast, matched for typical CMOS quantum efficiency and s/n ratio. Reflex-Blocker™ coatings, for largest ever freedom from halos, even under most adverse conditions concerning aux-optics

The Astronomik CLS CCD is suitable under light-polluted skies for DSLR Cameras, which have been remodeled for astronomical use. The filter enhances the contrast between all deep-sky objects and the background.

Baader H-alpha Ultra-Narrowband Filter – Premium Grade. 3.5nm FWHM to harmonize the exposure time from H-alpha with O-III / S-II), recommended for optical systems from f/10 to f/3.5. For highest contrast even at strongest light pollution

The Antlia H-alpha EDGE narrowband filter optimizes the FWHM (full width half maximum) to 4.5nm bandpass. The suppression of optical density (OD 5) on unwanted wavelengths and the excellent transmittance characteristics found in the Antlia 3nm Pro.

Antlia OIII 4.5nm EDGE filters are designed to deliver 85% transmission at the 500.7nm line that provides you with the maximum signal to reveal the faintest OIII nebulae structures.

High transmittance for working with both long focal ratios and fast optical systems (as fast as f/3 or maybe even f/2.8)!

Astronomik has added a new range of RGB filters to its line of World class products. The new Deep-Sky RGB filters are designed for maximum deep sky imaging performance with CCD cameras.

These Baader colour filters are carefully prepared for amateur astronomical use for contrast enhancement of lunar and planetary observations.
