Astronomik MC-Clear for Canon EOS 1100D-4000D, M3, M5 is precision optically polished and multicoated special glass. The glass is available in different sizes according to the requirements of the various Canon ® EOS DSLR cameras.

MC glass is mainly used to compensate the optical path of the removed original filter of the camera. Furthermore, it prevents dust from falling directly on the sensor, which may cause image defects.

The MC has no filter effect. It is blocking neither infrared nor ultraviolet light. The transmission is typically higher than 99.7%.

The retrofitted DSLR Camera needs, for proper imaging with camera lenses, light refracting elements such as flat field lenses or focal reducers, an additional filter in the beam path that blocked the infrared or visible spectrum of light, depending on the desired spectral range. For everyday photography, we recommend an Astronomik OWB-Clip filter that is snapped directly and without any tools into the camera body. The sensitivity and the white balance of the camera is being restored to its original state.

For astrophotography in the visible range we recommend at least an L-filter in the light path. For IR photography Astronomik offers EOS Pro 742 or 807 IR pass Clip filters.

A version of this filter is also available for the Canon EOS 1000D, 40D-250D, 450D-800D, 7D, M

The luminance channel is probably the most important for a successful astrophoto!

Sharpness, contrast and low noise of the luminance data are crucial to achieve the best possible quality in the finished result!
Astronomik presents three new UV + IR block filters for the luminance channel. The passbands are chosen so that with all optics and any CCD camera an optimally sharp and high-contrast recording can be obtained.

The task of the L-filter is to have the maximum transmission over the entire visible spectrum, because the combination of the widest possible transmission and high transmission makes it possible to detect the largest possible number of photons.

Unfortunately, not all telescopes or additional elements such as correctors, field flatteners or Shapley lenses have a perfect colour correction in the “real” world.

A too broadband L-filter can pass wavelengths for which your optics are not properly corrected.

The result is unattractive bloated, fuzzy stars that do not match the RGB colour channels.

The new Astronomik L-1, L-2 and L-3 filters eliminate or reduce the problem.

Check out:

The Astronomik Luminance Filter (L-1)

The Astronomik Luminance Filter (L-2)

Selecting the right filter:
Depending on the colour correction of the instruments used, the L filter with the largest aperture should be used. The L-1 filter has by far the largest spectral transmission, whereas the L-3 filter has the narrowest spectral window.
If your used optics can be classified as commonly “colour defect free”, the L-1 filter is the right choice. For general use, eg. For example, on telescopes of different colour purity or the use of additional, refractive elements in the beam path, we recommend the Astronomik L-2 version. For a “colourful” look, we recommend the Astronomik L-3 filter to increase the image sharpness.

The transmission characteristics and coating technology of the new Astronomik L series are designed to eliminate the need for halos or reflections. Even with bright stars in the field of vision, nebulae and galaxies with the finest structures and the highest contrast are depicted.

Like all filters from Astronomik, the L-1, L-2 and L-3 filters have an extremely resistant and durable coating applied to a fine optical special substrate as it is used in space applications.

The basic requirement for such material is freedom from streaks, tension and bubbles. Furthermore, the Astronomik filter carriers are machined to the same thickness in a single operation: Perfect homofocality and lowest wedge error are the resulting advantages!

A supplement for photographers under light-polluted skies:
Use the Astronomik CLS-CCD filter instead of a luminance! You get an L signal, without the lines of sodium and mercury lamps with much less background noise.

Highly satisfied feedback from customers around the world confirms the benefits of the CLS-CCD filter for the luminance channel, making it possible to colour-photograph the deep-sky sky in some regions!

The 6nm SII-CCD filter 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 SII line, the filter provides a maximum signal in the desired wavelength, but blocks all other radiation and thus ensures an extremely dark sky background.

The half width of 6nm is optimally tuned to the use of CCD and CMOS sensors with very low dark current.

The 6nm filters are the first choice if you are watching from a location with extreme light pollution or generally whenever weak objects in very star-rich areas of the sky are to be recorded.

Thanks to the new MFRF coating technology, it is possible to use the filter on all devices up to an aperture ratio of f / 4.
