I want an ultra-high magnification, super bright, and comfortable to use from a distance grain focuser for under my enlarger.

Right now, I use something like this. My unit requires you to twist a knob until a line in view becomes "sharp." I dislike that feature because it's hard getting that line as sharp as it should be. Also, the image is too small for me. I have to bend over like a contortionist to see it because of my cramped space. I'd love something that I could look at from a distance. I'd also prefer not to have to focus with that line method.

Do you have any recommendations?
