very interesting your circuit. A pity that I don't fully understand it!! So far I have four projects depending on LDRs and I'd love it to be able to understand it to apply it to mine.
I see your circuit controls the circuit hysteresis, the with of the hysteresis gap (I presume) and the shooting level, but there are a lot of things I don't grasp: 4 opamps? One of them in inverted configuration. Extra resistors (100 ohms. I'm sure they're not extra but I miss their meaning...).
I'll keep studying it and see if I figure it out!!
