How can I fix this LED dimmer circuit?

The circuit reversed blow is a LED dimmer which is driven by 555 timer in astable mode which then drives an op-amp to provide current for the gate of the MOSFET. The circuit dims quite well but it has an issue, when you power it up for a brief moment the LED strip receives non-PWM […]
