My scope kept losing stars after a few minutes. Really annoying for watching planets. I read some old forum posts for help. One guy said to check the motor gears. Mine had a bit of dust in them. Cleaned it out with a soft brush. Now it tracks smoothly all night. Feels great to fix it myself.
But was it really broken that bad? Sometimes these things just have a weird moment and then work fine. Might have tracked okay even without the cleaning.
