The Astronomik CLS Clip-Filter for Sony Alpha 7 and Alpha 9 cameras is used for deep-sky photography in slightly light polluted areas and can be inserted into the not astromodified camera body within seconds.

The Challenge:

Do you own a Sony Alpha digital camera for astro-imaging? Then you have surely encountered the following problems:

♦ Large filters for large camera lens objectives are very expensive.
♦ If you place a filter holder between your camera body and lens, you loose the ability to focus to infinity.
♦ For very fast (low f/ number) telescopes like the Vixen R200SS or the Takahashi "Epsilon" astrograph, a filter drawer or a filter wheel cannot be used since the distance to the corrector lenses would be changed.
♦ With long exposure times, your camera's sensor chip is exposed to more dust.

With the Astronomik Clip-Filter System you can take care of all of these problems at once!

The patented Astronomik Clip-Filters are made of black anodized aluminum and laser-cut on state-of-the-art machines. They can be inserted within seconds directly into the camera body. There are no changes necessary and all lens functions (focus, screen, image stabilization) remain operational!

The Clip-Filter System also acts as an outstanding dust shield, which prevents the possibility of dust settling on the sensor during long time exposure (The MC-Clear filter does not have a filter effect and only acts as a dust shield.)

Compatibility:

The Clip-Filter are sucessfully tested with the bodies Sony Alpha 7, 7r, 7s and Alpha 9. (Astronomik will test other/future models and add them here.)
