A 4mm lense in the 1400mm focal length will give a magnification of 350x. The theoretical maximum magnification of a 5" scope is about 250x on a stunner of a night and they will be VERY few and far between so the 4mm lense will just keep magnifying the blurring you get from overmagnification.

Cheers
