Adequate tripod question

[Gareth]

Hi everyone

I've just been given a manfrotto compact advanced tripod. The camera I would be using on in is a Nikon D3300 and the biggest lens I currently have is a Nikon 55-300mm that came with the camera. The box with the tripod says it will take entry level SLRs up to 200mm but it also says it will take up to 3kg.

I would like to do some long(ish) exposure photography with it so I'ma bit confused if it will be adequate. There's also no hook to hang any weight off the middle of the tripod either. Would tying something around the head to weigh it down help? Or should I just return it and get the next model up which can hold 4kg. The tripod came from **Company name removed** so I'm limited to exchange only.

Thanks

Gareth
