Re: What am I doing wrong?

Like Joe said, you're pushing the magnification of that scope to it's
limits. Occasionally, one can get away with that on something like
splitting double stars, but only on the best nights.
Also, those nights when the air is so still that you can use your
highest powers are RARE. Even though the image will be tiny, you're
usually best off starting with lower powers and then working your way
up. (This is especially true on dimmer deep sky objects.) Try to get
comfortable and look at your target for a considerable amount of time,
waiting for the moments of best seeing. As time goes by, your eye and
brain will learn to pick up more fine detail. Hang in there.
