Clip-Filter system for Sony Alpha 7/9 Mirrorless cameras

Do you own a Sony Alpha 7 or 9 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 are using an Off-Axis Guider stars will be dimmed on your autoguiding camera when a 2" round mounted filter is threaded to a corrector being ahead of the reflecting prism from the light path.
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-Filter System is black anodized aluminum and laser-cut on state-of-the-art modern machines. It can be inserted within seconds directly into the Sony Alpha camera body. There are no changes necessary and all lens functions (focus, screen, image stabilization) remain functional!

After a long period of prototyping and development we are now able to offer you Clip-Filters for the amazing Sony Alpha bodies. The filters are held in place save and secure with no stress to the high quality glass and only minimal obstruction in the corners.
The Clip-Filter are designed and optimized to be used with normal lenses and with telescopes as well.

Description

Astronomik MC-Clear Clip-Filter Sony Alpha 7/9

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 doesn’t modify the spectral transmittance of your system it doesn’t alter the colors. It’s 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

Important: Full Spectrum modified cameras will need an additional IR-block-filter.
