This was more evident in the 10mm eyepiece than the 30mm. Is this normal as well or is there something wrong with my telescope?

This why motorised focussers were invented. My Moonlite converted my 15cm f/8 refractor from frustration to bliss. I've gained at least 0.5 mag just by being able to get the focus spot on. The dobs is still manual focus because they are more stable but even then you need a very soft touch to keep the vibrations acceptable.
