ZWO' have finaly released the new generation Sony 60MP 35mm CMOS sensor, its very low noise, great well depth, high dynamic range and very sensitive. It's also one of the new zero amp glow derivatives so thats one less thing to worry about :)
This camera is set to manual Gain of 100 as our default as this is recomended by ZWO, if you have any special gain and offset requirements for CMOS imaging please discuss and we will do our best to accommodate you.
Please note: The maximum sub length we will do on this pier is 300s
