Hi Dallas
I wouldn't bother with daylight tests at all. These cameras are, indeed, very sensitive and I've only ever operated mine at night and in dark conditions. Don't right it off because the instructions might call for daylight testing. Even if you pop one edge of the guide scope's cap in daylight you'll flood the sensor. Merely pointing at a black surface will prove nothing either, you need to cap it with a black light-proof cap. If you do this and run in live mode - and still see a washed out result, then you need to reset to defaults and try again. Let us know how you go
