Some of my most memorable flights have been at night.
Departing from Bodo Norway at night and breaking out on top into sky illuminated with red and green aurora borealis.
Low level departure from Biggin Hill north bound and over flying central London 2000' brilliant white lights rather than the drab sodium yellow (this departure unfortunately no longer possible thanks to OBL)
Night departures watch out for horizon gyro precession whilst accelerating - can give a presentation of a climbing turn! Not good when ascending into the inky black! Easier to get "uncertain of your position" unless you are up to speed with IFR navigation. You need the right aircraft - properly equipped.
Most enjoyable rating I ever did and enjoy night flying its huge fun.
Standard caveat - no strobes whilst taxiing - akin to using fog lights on your car in good vis!
