thanks for that link to the guide. i spent all but ten dollars of my last weeks wages before the holidays on acquiring the scope. the collimation tools will have to wait a week or two sadly.
yes i know the two thumbscrews that you mention. i could lock the focuser quite easily the other thumbscrew maybe meant to tension the focuser however it doesn't seem to work like that for me. well to further clarify my point even with both thumbscrew really loose turning the focuser only moves the eyepiece about 5 mm outwards at the start then it slips and the eyepiece doesn't move any further regardless of how much i turn the focusing knob. i can rack the eyepiece in and out by hand quite easily. not sure if thats a good or bad thing. im working away from home till friday night perhaps my thinking is flawed and i need to tighten that second screw to make contact to the focusing knob i'll have another look at it this weekend.
the trees were only for visual gratification just to see that i didn't break it on the trip somehow considering the nights had been really ordinary i had to do something
