Hi Lee
Nice job with the light box, the results look very promising – well done! I used single high intensity LED’s (x6) and mounted the LEDs in the “mouth” of my light box so they reflected back down the bucket I used, to then reflect back towards the OTA aperture where they were further diffused by a sheet of opaque Perspex.
I usually plan to shoot 10 Flats and then do a Median Combine and it makes a significant difference to the appearance of the combined Flat. The graininess almost disappears and the final median Flat looks so much smoother. I think the recommended exposure is that required to fill the well depth of the sensor to around 30%?
I’ve yet to test mine!
Cheers
Dennis
