Most problems will be overcome by reading and absorbing the instruction manual.

Assuming the telescope is in good order, it must first be pointed at a light source using the spotter scope and then aligned using the lowest power eyepiece before fitting the high powered eyepiece...

You also should be in very low light conditions.

Sky Prodigy does not have you align on stars but self aligns on images from the mount's camera (much like satellites do to orient), so ignore any incorrect suggestions about picking alignment stars, centering them, moving axes, entering correct dates or info. You should just turn it on and it figures everything out in 10 or so minutes alone.

Thiscode is likely a hand controller failure and you need to call Celestron. Mine did this too. good luck, you will need it...

Do you mean resolving power or magnification power ?

Do stars appear as small pinpoints in your scope? If not then it sounds like you have not adjusted the focus properly. I recommend you take your telescope outside in the daytime and point it toward a building or tree or hilltop that is somewhat distant from you. The exact distance is not important, but it should a block or more.

With the telescope pointed at the distant object, focus the telescope until the object is sharp and clear. The object might appear upside down -- that's normal for many astronomical telescopes. When you have achieved a sharp focus, leave the focus control alone until you are outside at night under the stars.

The focus should now be fairly close for viewing stars and planets. Small adjustments of the focus control may still be necessary for the sharpest view.

Venus is sometimes a difficult object. It is often fairly low in the sky where the atmosphere is most likely to blur the view. Find a bright star and focus it to a pinpoint, then swing your scope toward Venus.

With the setup you have, you are attempting a magnification of x 750, which is way beyond the capabilities of your scope. A realistic limit to usable magnification is x 250, or about what you will get if you take the barlow off and just use the 4mm lens.The 127mm aperture on that scope does not gather enough light to do more.

Even that depends on good seeing, that is, clear air and no light pollution. It is a great shame that scopes are marketed with outlandish claims as to magnification. You certainly will see a magnification of x 750 in daylight, when there is lots of light, but they don't tell you that trick.

I have a 200 mm scope, with a practical limiting magnification of x 400, and I find that almost impossible to use. The viewing object is hard to find and keep centred in the eyepiece, it wobbles around, it soon disappears due to the rotation of the heavens, and is dim and blurry. I keep to magnifications of about x 250 max.

Use the finder scope to locate the object in question, then main scope will be aligned for magnified viewing.
