Dichroic Filters for Omega F

JackRosa said:

Hello to my fellow APUG members and my thanks to all for sharing your insights with me and for providing very valuable advice. Special thanks to IC, who was kind enough to take time to PM me numerous times to guide me through a systematic trouble-shooting process. Thanks to his guidance, and to the advice I received from all of you, I was able to systematically dissect the problem.

I cleaned the dichroic filters and used a color analyzer to assess whether increases in Magenta or Yellow filtration were "seen" by the analyzer. These changes were indeed seen. I also looked at every possible source of light leaks and moved the 21-step tablet to the center of the contact frame. I re-ran the contrast tests at various dichroic filtration settings for both, yellow and magenta.

I am delighted to report that the tests reflect that everything looks OK with the Omega F dichroic filters.

Thanks again to all. You have been most helpful.

Jack
