Chroma H-Alpha 5nm Narrow Band Filter
The Chroma H-Alpha 5nm Filter is essential when imaging objects rich in ionised hydrogen, works well in light polluted areas and moonlit conditions.
The Baader Complete Filter Set – 36mm, contains an LRGBC filter set as well as the three Hubble palette emission line filters, Ha 7nm + OIII 8.5nm + SII 8nm.
Consists of 8 Filters (2459546) glass thickness is 2mm.
The Astronomik OIII CCD Filter 12nm enables high contrast imaging of planetary nebulae even with moonlight or in light polluted areas.
Please note this is the CCD filter which unlike the cheaper “visual” version does not pass Infra-red light!
Astronomik IR Pro (807nm) Filter – This filter extends the IR passband much deeper into the IR.
These very long wavelengths allow planetary imaging in poorer seeing conditions than normal.
The sensitivity of most CCD cameras is reduced in this region so scopes of over 8″ aperture draw the most benefit.
Astronomik Deep-Sky RGB Filterset
Astronomik offers an additional series of high-end RGB filters: The new Astronomik Deep-Sky RGB filter set is specially designed to meet the needs of modern astrophotographers for maximum image quality with all CCD cameras.
Use the Deep-Sky RGB Filter Set to capture images with unparalleled sharpness, contrast, and vivid color.
The Astronomik OIII CCD Filter 6nm dramatically increases the contrast between hydrogen fog and the sky background.
Due to the combination of low half-width and high transmission of almost 100% in the area of the OIII line, the filter delivers a maximum signal in the desired wavelength, but blocks all other radiation and thus ensures an extremely dark sky background.
The Baader Neodymium filter is a general purpose contrast filter for Lunar and Planetary observation and also helps reduce light pollution from Sodium lamps. MC coated and IR blocked.
This high quality manual filter wheel allows you to switch between 5 x 1.25″ filters without removing the camera.
At the same time the filters are always safely stored and protected against dew.
The filter wheel is suited to both imaging and visual use and is the most robust low profile filter wheel available at this price.
The Astronomik OWB Type 3 Clip-Filters (Original White Balance) restore the colour balance of an astro modified DSLR to make it suitable for use on terrestrial subjects.
The QHYCFW3-S-SR (7 x 1.25″ / 31mm) Filter Wheel is the perfect addition to the QHY183M and similar cameras with smaller sensors.

The Astronomik Luminance Filter (L-3) is a high quality UV / IR block filter
Baader Narrowband enforced 3.5nm H-alpha Filter 2inch
These 3.5 nm H-alpha Enforced-Narrowband Filters open up the extremely narrow 3.5nm H-alpha world.
This enforced contrast results in even fainter stars, providing more signal of faintest nebulae detail. Manufacturing such ultra-narrow filter does require extreme coating homogeneity and very high CWL precision, which these filters are designed for (CWL= Center-wavelength).
Astronomik CLS XT Clip-Filter EOS APS-C
The Optolong L-Pro filter is designed to provide maximum transmission of the spectrum, except in those areas affected by light pollution.
This listing is for the 2″ filter and the price includes UK delivery.
Please ask about other sizes.
This Astronomik SII CCD Filter 6nm is suitable for photographing SII regions from artificially polluted areas as well as places with dark skies. The contrasts between objects that glow in the light of the sulfur line at 672nm and the sky background are greatly enhanced.
The 6nm SII-CCD filter dramatically increases the contrast between hydrogen fog and the sky background.
