I get that you are saying it is a matter of being able to see better for focusing. My eyes are 52 and not as good as they were when I was younger either. I use a wratten 47b blue filter and I'll try it but I think the "filter factor" is too much-- the image is a lot dimmer. ( Also I understand you are talking about a filter for your focus scope... I don't have anything like that... )

On another thread about grain focusers I mentioned that I would try getting some reading glasses from the drug store... I did and it makes a huge difference. Now I can see when my print is in focus... I'm happy now.
