Hi Americo,Don’t know if this helps…I’m building my own light box for to be used for photometry. I’m finding it difficult remove all gradient. I’m taking so much care as I think the precision for photometry is much higher than for imaging.I know someone who uses EL panel his only criticism is that you must reduce the luminance by diffusing to extend the expose time. Otherwise the a strobing effect appears in the flats in very short exposures.Cheers,Eliot
