To really appreciate this effect your lens should stop down to f22 or higher (rare) this gives the inage a sense of depth as well as star effects on highlight spots. The filters are good but lack this certain depth created In Camera.

My only problem is my sensor is quite small, so it's impossible to get anything out of it without using a high ISO, which presents the problem of huge amounts of noise!

That's generally why I tend to stick to filters, rather than trying to use a narrow aperture- it's not worth the hassle of having to edit the image in Photoshop afterwards!
