These are common beginner concerns so you are not alone. First, leave the barlow in the box, for now and just use the eyepieces without the barlow. Using the barlow with the MA9 mm is producing too much magnification - the most common beginner's mistake. As magnification goes up, your telescope
is going to be much harder to use in every way. Always Use the MA 25- your low power eyepiece - to locate an object, first, then trying bumping up magnification with the MA 9 after being very careful to center your target
in the center of the field of the MA 25 before swapping eyepieces. All this assumes that your finder scope is properly adjusted, too. If not, you will have a devil of a time finding objects with any eyepiece. The easiest way to do that is to first locate a distant object on the horizon in your telescope
eyepiece by day and then adjusting the finder scope so that it sees the same object. You can then fine tune as needed at night with the moon.
