I have a 10" dob, and can usually keep the object in the fov quite easily even with a 5mm eyepiece by nudging ever so slightly. if I totally lose it, I just use the finderscope.
with the finderscope I adjust it's alignment with each EP up to around 15mm, then it's usually spot on with my eps under 15mm. if I go lower I usually centre the object in the ep, and quickly switch to finder to note its position and where to relocate it if I go inside, lose it totally .. etc.
