Astronomik ProPlanet 807 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.

Ideal addition to the Astronomik ProPlanet IR 742 for imaging the moon and planets, with telescopes larger then 10" (250mm) when the seeing is poor.

This filter is an ideal complement to the ProPlanet IR 742 for use with converted DSLR cameras, CCD cameras and Webcams. The effects of seeing are distinctly reduced. It is your entry into previously unknown dimensions of photography of the moon and the planets.

The ProPlanet IR 807 only allows infrared light with wavelengths of more than 807 nm to pass. In this wavelength range the effects of seeing are significantly lower than in the visible spectrum of the human eye. This allows much sharper images than are usually obtained from your device and location. Another advantage is that the sky background of advanced dawn is dark and even allows photography of planets and moon at daylight.

Main use

The Astronomik ProPlanet IR 807 cuts off the visible part of the spectrum and allows the light of wavelengths longer then 807nm to pass. Due to this behavior the part of the spectrum that is most sensitive to bad seeing is rejected. This approach does a big improvement to the imaging of planets and the moon. The image is more steady than the image in the visible light.

Other uses

• The Astronomik ProPlanet IR 807 is designed to be an addition to the Astronomik ProPlanet IR 742, if the seeing is extremely bad and a larger telescope is used.
• For most cameras the exposure times doubles, compared to the Astronomik ProPlanet IR 742 or imaging in visible light, if the Astronomik ProPlanet IR 807 is used.
• Darkens the background during twilight.
• Imaging of bright planets, stars and comets by day.
• Imaging of young stars in dust clouds and stellar nurseries.

Alternatives

If the seeing is not so bad or if the telescope is smaller than 10" (250mm) we recommend the use of the Astronomik ProPlanet IR 742.

Suitability

• Visual observation (dark skies): Unsuitable, the eye is insensitive at this spectrum
• Visual observation (urban skies): Unsuitable, the eye is insensitive at this spectrum
• Film photography: Unsuitable
• CCD photography: Reasonable, for special IR photography (as chlorophyll)
• DSLR photography (original): Unsuitable
• DSLR photography (astro modified): Unsuitable
• DSLR photography (MC modified): Good, for IR daylight photography, longer exposure time
• Webcam / Video (Planets): Very good, rejects problems with seeing, particularly with telescopes larger 250 mm aperture
• Webcam / Video (Deep Sky): Very good, rejects problems with seeing, particularly with telescopes larger 250 mm aperture

Technical Data

• more then 97% transmission for wavelengths of 807nm to 1100nm
• blocking of wavelengths between 350nm and 790nm
• 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
