    Also check the position and alignment of the bulb holder. I no longer have my 600 series Durst, but remember it having significant adjustability to accommodate both tube and globe bulbs.

    Ah but Tim, you're referring to the B&W head with the almost regular bulb/globe that can be moved in/out from the rear of the head, aren't you?? This is the color head that I have, the halogen light source doesn't really move about/make a difference, does it?

One thing I do to center things is to use a larger glass holder and fiddle until the negative is in the center.

    I do it by shining the laser right up at the lens and it makes a circular diffraction pattern when it is in the exact center. I mark this center on the baseboard and then move the negative carrier or the negative in the glass until the center of the image is where my center mark is on the baseboard.
    You're talking about something like the 'The Versalab Parallel' tool, aren't you? Or have you made your own tool? I get what you mean, only I'm wondering where I might find a laser that can stand up by itself under the lens there pointing directly upwards, rather than some keychain laser pointer like what kids use to point at airline pilots as they try to land.....

    If you don't have a laser, another method is to use the larger (6x6) light box setting and take the negative carrier out. Your lens should then cast a circular shadow. Position your easel equally in the middle of the circle of light. Then put the negative carrier in and see where it lines up. My bet is that one corner gets cut off when you put the 35mm negative carrier in.
