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...
Equatorial mounts need to be polar aligned to work correctly. Once the scope is polar aligned (see manual or look online for polar alignment instructions), turn on the RA motor. Loosen your RA and DEC locks and find a object you want to view, The motor should keep the object in view for a while (depends on how good the motor tracks and how good your polar alignment is.) Spending 10 minutes polar alignment on my C8 keeps the object in view for about an hour without adjustment.
No manual available and I could only answer general questions about the use of this scope but would take a lot of room. Suggest you join Cloudy Nights or Astronomyforum.net. Post this question to the SCT forums. You will get a lot of great information from how to set up, align, and get the most use out of this scope. The optics are not the greatest and has lots of non-standard threads for accessories but SCTs are very versatile scopes
1. Failure to follow the manual and do all the initial setup. Time, date, and site, and usually training the motors.
2. I don't understand #2.
3. Focus until the stars are pinpoints of light. If you see donuts with a dark center you are NOT in focus. Practice during the daytime on a distant object using the eyepiece with the largest number written on it. The moon should be your first target at night.
4. Many things, broken gears, failure to train the scope, grease on the clutches, hand controller is set for terrestrial viewing instead of astronomical viewing so tracking is NOT turned on.
Read my TIPS about GOTO scopes in my profile page.
This is called "rubber-banding". Your scope needs to be re-trained.
So, setup a target during the day at least 100 feet away from the scope (200 feet would be better, Calibrate motors using the same power source you use at night, and Train Drives. Later after dark, do a Calibrate sensors on Polaris.
You should train drives about once per year, and calibrate sensors about twice per year.
You may want to update the firmware before you Train Drives. The latest version is 43Eg available on the Meade.com web site. You with need the Autostar Updater Software also available on the Meade web site under Customer Service---- Downloads. Version 5.9
