Smile Removal of IR Blocking Filter for a Canon 20D

Hi All,

I was feeling brave last week so I done a little job that I have been putting off for weeks ! I removed the IR Blocking Filter in front of the CCD to improve the Red Spectral Response of my 20D.

All went well as the camera is still working and I am looking forward to giving it a feild trial on the next new moon, something like the Helix Nebula which I had a lot of trouble with last year due to the poor Red response of the camera.

This weekend I spent some time to document the process to remove the filter for the 20D. If anybody is considering doing this, you can access this document at the url below.

I will contact Mike later to see if this is something that he would like on this site as well.

I hope it helps someone in the future.

Thanks

Chris
