i thought so too! till i tried it!
honestly, i thought i could set to infinity and voila! ! but its not true..
focusing is 1-2mm adjustment either side of the focus ring to get the focus required. i already zoomed in on the LCD liao, 4.8/9.6X, but its damn hard cos after each adjustment the things shakes like earthquake (so i wont know i got the focus till afew sec after to let it settle down). and the moon is moving pretty fast at that magnification! within less than a minute, gotta readjust the camera (and the focus!) again cos its no longer in the centre.
silvermoon: perfect weather last night.. cloudless and hazeless as far as i can see.
rashkae: already using the magnification to verify focus, BUT the thing shakes like crazy each time i touch the setup, so gotta let it settle btwn each focus, and 3-4 focus later, the moon moves out of the centre, then gotta adjust the camera/tripod setup. back to square one!
