:help:I've created a problem with my finderscope - a bit dumb on my part! :screwy:
I have a GSO 8x50 finder - this one, but in battleship grey:-

Now, I had an alignment problem I asked about previously:-
http://www.iceinspace.com.au/forum/showthread.php?t=20628
So today I tried to do something about it which included screwing off the tube containing the eyepiece and the cross hairs. Somehow I managed to damage the crosshairs so thought, no problem, I'll replace them. Uncrewed the locking "ferrule" which held the crosshairs (and the front eyepiece lens - one I thought) in place. Replaced the crosshairs with new pieces of fine copper wire - glued in place and trimmed off. Then somehow, I managed to tip the contents of the eyepiece tube out and ended up with two plastic spacers and two lenses - all of different shapes - one lens is a composite lens. It's not immediately clear what is the correct orientation of these components. I've tried a few different orientations, with anywhere from terrible to "a bit off" results.
Later today (OMG - look at the time!), I'll set about systematically trying all orientations and checking the result each time - hopefully one is clearly right.
However, if someone knows the correct orientation of the contents of this eyepeice tube, I'd be very grateful.
If someone was willing to pull their's apart to tell me what it should be, that will deserve a reward of some sort!
