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 QHYCFW3-M-US (7 x 36mm) Colour Filter Wheel is the perfect addition to the QHY268M camera and many others with APS-C and smaller Sensors.

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.
OIII 3nm Narrow Band filters isolate the doublet emission of doubly ionized Oxygen.
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.
Comparison between Baader UV/IR cut and Astronomik IR Pro 742 filters
Chroma LRGB Filter Sets contain 4 x Individual Filters
SII filters isolate the emission from ionized Sulfur atoms, also common in nebulae.
The Baader UV IR Block L Filter is excellent at blocking UV and IR, passband is 420nm – 680nm.
The Astronomik Luminance Filter (L-2) is a high quality UV / IR block filter
The Astronomik H-Alpha CCD Filter 12nm enables high contrast imaging of emission nebulae, even with full moonlight or in light polluted areas.
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″)
Astronomik MC-Clear Glass Filter, a high Optical Quality multi coated filter, when full spectrum transmission is required. Scratch resistant and par-focal with other Astronomik filters. Price includes delivery.
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.
