Astronomik OWB EOS Clip XL filter

Product code: AS8H00J1

Quick Overview

The OWB filter would usually not be designated as an "astronomical" filter. The intention is to enable converted DSLR cameras (without inbuilt IR-filter) in order to be used for 'terrestrial' photography.


The EOS Clip XL model plugs directly into the Canon EOS camera body (compatible with all Canon EOS Full Frame 24x36mm sensor camera, except for 5DS) so it is very practical to use.

Details

The OWB (Original White Balance) filter shifts the complete spectrum of a converted DSLR in such a manner that the camera will not be exclusively usable for astro-photography. Therefore the decision, which in former times had to be made, whether to 'victimize' a DSLR in order to exclusively use it for astronomical tasks or accept the lower sensitivity on the red end of the spectrum it is now a thing of the past and disencumber your purse, too.

The OWB EOS Clip filter fits in all APS-C sized series of cameras from Canon: 20D, 30D, 40D, 50D, 60D, 70D, 7D, 300D, 350D, 400D, 450D, 500D, 550D, 600D, 650D, 700D and it also works with the 1000D, 1100D and 100D.

 

Main use

DSLR cameras which have been converted for astronomical use by removing the inbuilt IR-filter or by substituting it with a filter with greater range for H-alpha, have a white balance that made them unable for 'terrestrial' purpose. The spectral sensitivity of the DSLR will be changed by an OWB-Filter to the former range. In other words: The OWB pretend to be the conventional built-in filter!
