The mistake when people first try to find this object is to use a telescope at too high a power.The full extent is several degrees so you are better off with binoculars.It is visible with the naked eye but you do require reasonably dark skies.I do assume you know where it is (it is pretty well placed at the present).In 7x50 binoculars it is unmistakable, appearing as a 'fuzzy' ellipse.Don't expect to see anything like the imagers you see in magazines or books, even large amateur telescopes will not show it like that,good luck.
