Astronomik MC-Clear Filter Clip-Filter EOS XL

Since 2007 we do offer our extremly popular Clip-filters. Customers looking for a filter to be used with the "big" Bodies containing the Full-Format sensors, had to buy large (and expensive) filters to be screwed in front of a lens, as Clip-Filters were available for the APS-C sized bodies only.
All customers asking for Clip-filters for the Full-Format bodies were told "We are working on it, please wait!"

Now waiting is over, and we are proud to show you the result of our R&D:

Clip-Filters for Canon Full-Format Cameras 5D Mk II, 5D Mk III and 6D. (5D Mk I will work without LiveView only, the 6D MkII will not work with XL Clip-filters)
Please note that the XL-Clip filters will not work with the Canon 5DS, 5DSR, and the 5D Mk IV

These Clip-Filters can be installed with your fingers only. Mounting and removing the Clip-Filter is quick and easy. It can be done at any time. No tools or modifications to the body are necessary to use the Clip-Filters.*

If you are new to astrophotography and looking for your first filter: We do recommend getting the Astronomik CLS!
The CLS gives you maximum contrast due to it effective surpression of artifical light pollution, but still gives you neutral and well balanced colors. With the Astronomik CLS you can do very deep images of amazing quality even form a urben/suburban observing site!
For the advanced Astrophotographer we do offer a wide selection of filters: Perfect accessories for all kinds of astrophotography. To compile a usefull selection of filters for your obeserving goals we would be happy to give you advise, either via phone or eMail.
The full range of Astronomik filters is available as Full-Format Clip-Filters now. NEW: The OWB filter for daylight-photography with modified cameras is available now too.

* You might want to modify your camera to get a maximum sensetivity at H-alpha and SII for Astrophotography. But this has nothing to do with the Clip-Filters! You may use the Clip-Filters without any modifications to the body. (But some filters like H-alpha and SII-CCD might not make sense with an unmodified camera.)

Mounting the Astronomik EOS XL Clip-Filter:

Mounting the Astronomik EOS XL-Clip Filter is very easy: You don´t need any tools and filters may be changed at night without any problems.
Activate "Mirror Lockup" in the Custom-Functions Menue and press the exposure button once: The flip-mirror goes up and stays there.
Now slide the XL-Clip-Filter into the body and press it in, until it rests on both arms (right & left).
Deactivate the Mirror-Lockup and your camera is ready for imaging!

Remark:
The installed XL-Clip-Filter fixes the flip-mirror in the upper position. -You can´t use the optical viewfinder as long as the XL-Clip Filter is installed. For Searching, focusing and centering you should use the LiveView monitor on the back of the camera or the remote-controll via USB cable. All functions like Autofocus and Image-Stabilization remain fully functional.
The fixed flip-mirror does not cause any kind of problems or error-messages!

Removing the Astronomik EOS XL Clip-Filter:

Removing the Astronomik EOS XL Clip-Filter is very simple: Pull the filter out with one finger an on arm (either right or left), get the filter with two fingers and put it into it´s storage box.
The flip-mirror goes down and the camera is working as before.

This Multicoated (MC) glass serves as dust protector or to keep your system parfocal with other Astronomik filters.

This filter should be used if the focal plane of your imaging system should stay in the same place as with other Astronomik filters in place. The multicoating prevents you from unwanted reflections. It blocks neither IR nor UV.

The second main application is dust protection of your system (telescope or camera). As the filter doesnt modify the spectral transmittance of your system it doesnt alter the colors. Its great for keeping all dust away from your optics or sensor.

Lots of Astronomik MC Clear filters in custom diameters are sold to camera manufacturers worldwide. They like the great coating and scratch resistance!

Main use

The Astronomik MC Clear is made by the same high-end process as all other Astronomik filters. The coating has the same scratch resistance and the substrate has the same high quality. Because of this it is parfocal with all other Astronomik filters and can be used in any optical system for dust protection without modifying the spectral characteristics and without destroying the optical performance of your system.

Other uses

• As a dust protection of Schmidt-Cassegrain, Schmidt-Newton or Maksutov system or as a dust protection in front of DSLR camera.
• As an alternative instead of the UV-IR-Blocker if your system has no refracting elements.

Alternatives

You should think about using the IR-blocker or even the UV-IR blocker if you have a system with any refracting elements.

Suitability

• Visual observation (dark skies): Reasonable, for dust protection only
• Visual observation (urban skies): Reasonable, for dust protection only
• Film photography: Reasonable, for dust protection only
• CCD photography: Good, to compensate the optical thickness (parfocal with other Astronomik filters); dust protection
• DSLR photography (original): Reasonable, for dust protection only
• DSLR photography (astro modified): Reasonable, for dust protection only
• DSLR photography (MC modified): Reasonable, for dust protection only
• Webcam / Video (Planets): Reasonable, for dust protection only
• Webcam / Video (Deep Sky): Reasonable, for dust protection only

Technical Data

• Parfocal with other Astronomik filters
• Glass thickness: 1mm
• Completely resistant against high humidity, scratches and aging effects
• Diffraction limited, the filter will not reduce the optical performance of your telescope!
• Astronomik filters are delivered in a high-quality, long lasting, filter box
• Since 2008 we do ship filters with a completely new design. Any kind of halo or strange reflection is a matter of past
