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.
 

Astronomik CLS Clip-Filter Sony Alpha 7/9 (For Enhanced Spectrum Modified Cameras)


The Astronomik CLS is also a budget filter for visual observation, Black & White photography and CCD photographs of nebulae, galaxies and star clusters with astronomical instruments of any size.

The Astronomik CLS blocks the light of the spectral lines of mercury and sodium-vapor lamps and lets the largest part of the visible light and H-alpha emissions pass. All the important emission lines, as well as the spectral region that the very well dark adapted eye can see, can pass through the filter.

 

Main use

The filters are optimized for use with aperture ratios from 1:3 to 1:15. Transmission losses and chromatic distortions, which are problems with other filters, only appear with Astronomik filters when extremely bright aperture ratios of 1:2 and more are used. The CLS filter is suitable for use with telescopes of all aperture sizes.

 

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