The Baader DSLR Conversion Filter 7-40-50-60-400-450-500-550-600-1000-1100D replaces the internal filter and passes Ha very efficiently, eliminating the cameras’ major disadvantage for astro-imaging.
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.
Chroma H-Alpha 3nm Narrow Band Filter
Chroma H-Alpha 3nm Narrow Band Filters are essential for ultra high contrast images of nebulae under high levels of light pollution.
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 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 Baader UV IR Block L Filter is excellent at blocking UV and IR, passband is 420nm – 680nm.
The QHY Filter Wheel 3 Medium Ultraslim (QHYCFW3-M-US) is 17mm thick and weighs 675g
Please state desired configuration in customer notes when ordering.
It’s available in the following configurations
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
New LRGB CCD filter sets from Baader, available in many combinations, all filters are parfocal and complement the existing Narrowband filters.
Baader Photo AstroSolar Film ND3.8 (imaging only), telescope quality for digital solar imaging at high magnifications with short exposure times. Not suitable for visual Solar Observation! ND3.8 film is 20 x 29cm (7.9″ x 11.4″)
Chroma LRGB Filter Sets contain 4 x Individual Filters
The Baader U (Venus) Filter enables amateurs to successfully image in the deep UV from 300nm to 400nm. The filter has a peak transmission of 80% and completely blocks the rest of the spectrum from 200nm to 1500nm.
Used to record cloud structures on Venus, the Solar Calcium K-Line is also within the passband of this filter.
OIII CCD filter for narrowband imaging.
