M57's central star is apparantly magnitude 15 and at low power i keep thinking that I can see the central star but upping up the power makes the star dissapear.I am not sure what is the cause, a physcological problem or power related problem.

Also the nearby galaxy Ic 1296(mag 14.8) seems to come in and out of view,Phychological or seeing?

I really don't know.

Cheers Orestis
Increasing magnification helps with faint stellar objects and is certainly beneficial for tiny faint galaxies. This is because it has the effect of darkening the background sky increasing contrast. Recently I was observing Uranus and Neptune and their moons were easiest seen at the highest power I could use within seeing limitations.
