Re: Orthoplan's chromosomes
Beautiful work, as usual. Sensor: are you sure you damaged it? Perhaps it would be wise to take it to a camera repair professional to have a look at it. If you did scratch it, I don't think it would not be the sensor itself, as the sensor is covered by a filter, which may be replaceable by Canon or ...

Re: Fossil Actinoptychus
Rod, fantastic work! Great images! Colors and all.
Colors: I think charlie g got it almost right-- the regular pattern of the diatoms is in effect a 2-d diffraction grating, and the colors I think are due to the light being diffracted (rather than refracted) by the "grating".

Many thanks for taking the time to explain in detail. Not much leeway between excitation and emission ranges. Nice sharp cut-off filters.

Re: Diatoms and an Amoeba (perhaps)
Very beautiful images. I think the large round thing that has gobbled up the little algae is an amoeba of genus Thecamoeba but,as always, I may be wrong.

Re: Re-rated bulb life formula
For what it's worth, I usually run my 12-V 50-W tungsten halogen lamp at 75% to 90% of rated voltage (according to the microscope's voltmeter). I had it burn out once only, and when I replaced it I noticed no blackening at all. I myself don't care about the color temperature (but maybe I should) bec...
