The Astronomik CLS Filter (not IR blocked) is the best deep sky and general purpose filter and one of my favourites.
This broadband light pollution filter works on all objects for both visual use, and imaging with standard and Baader modded DSLR cameras.
Blocks Sodium, Mercury and air-glow emission.
Can also be used as an effective minus violet filter by refractor owners.
Not UV / IR blocked.
The Astronomik CLS CCD Filter IR Blocked has all the benefits of the standard CLS CCD filter but with IR blocking built in.
This broadband light pollution filter works on all objects and can be used visually and for imaging with CCD and plain glass (full spectrum) modded DSLR cameras.
The IR Pro (742nm) Filter pushes the passband of the Baader and Altair IR pass filters further into the Infra Red. At these longer wavelengths, planetary images are much less disturbed by distortions in the atmosphere.
This is the best “Planet Killer” filter, based on research by Astronomik to determine the optimal passband for enhanced Planetary Imaging, with most amateur equipment.
Sensitivity of most CCD cameras is still fairly high in this region so smaller scopes (>5″) can benefit.
The Astronomik H-Alpha CCD Filter 12nm enables high contrast imaging of emission nebulae, even with full moonlight or in light polluted areas.
The Astronomik Luminance Filter (L-2) is a high quality UV / IR block filter
Astronomik MC-Clear Glass Filter
High Optical Quality Plain glass filter, when the full spectrum is required.
Scratch resistant and par-focal with other Astronomik filters, makes a useful dust seal.
Astronomik UHC Filter – This filter was designed for the visual observation of emission and planetary nebulae but also works well for imaging these objects if used with an IR block filter.
Good results can be obtained with modified DSLR cameras.
Top of the range IR block filter.
This IR-blocker is optimized for systems with focal ratios between f/0.5 and f/50, typical transmission is higher than 99%.
Suitable for cameras with low sensitivity in the UV such as webcams and the Meade DSI and LPI.
The Astronomik H-Alpha CCD Filter 6nm enables high contrast imaging of emission nebulae, even with full moonlight or in light polluted areas.
The contrasts between objects that glow in the H-alpha light and the sky background are greatly enhanced.
The 6nm H-alpha filter dramatically increases the contrast between hydrogen fog and the sky background.
The Astronomik SII CCD Filter 12nm enables high contrast imaging of gas nebulae even in moonlight or light polluted areas.
The Astronomik LRGB Type 2c Colour Filter Set contains 4 x Individual Filters.
Luminance – Red – Green – Blue
Used to create high quality colour composites with monochrome cameras.
These filters are well priced high quality dichroic LRGB filter sets.
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.
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.
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.
