i know that stars are like.... suns, but i hope you are not ecpecting to see a little ball of fire that looks much like our sun... it just wont happen no matter what size scope you have.
reducing you magnification will resolve if to more of a pleasing point of light
dont barlow your EP unless you are trying to split a double or sumpin otherwise you will get the effect you described
I stared with a scope similar to yours but smaller (60mm) and you can get a wealth of objects with it, just dont magnify too much
