Hi Craig,

I assume you've shifted/nudged the scope slightly when trying to see the moon, and racked the focuser fully in and out to see if you can get a focused image - it doesn't take much for a finderscope to be misaligned with the main scope, so just because you can see it through the finderscope doesn't mean it'll be bang in the middle of the eyepiece. No doubt you probably need some collimation, but I've never heard of a dob being so far out of whack that you can't even get some sort of rudimentary image focused. At this point of the lunar cycle, even a very unfocused moon should present as a fairly blinding light taking up a fair bit of the field of view with the 25mm EP and probably covering the field of view with the 10mm EP.
