Gskyer telescope how to focus?
If you are struggling to focus on the moon with Gskyer's Refractor Telescope, then use a 10mm eyepiece with a 40x magnification to focus and look at the moon's craters in high clarity.
Gskyer telescope review:
Pros: Easy to set up; Has compact, good quality build and is easy to carry and store (isn't too heavy); Gets clear picture quality. Cons: Locating target can take some practice; 400mm is good enough to see the moon, but checking out stars is a bit more tricky
