The compass needs to be accurate not "an Improvement" what I do is use the orienteering compass because it has a rectangular base, run a straight edge between the north facing tripod legs then butt the compass up to the straight edge. then mark the spots where the tripod lands so you wont have to realign every time the scope is dragged outside.
once this is done check the meade supplied compass it wont even be close to correct something to do with the fact that it is in the middle of the metal wedge and this throws off or introduces anomalies in the magnetic field.
Same goes for the spirit bubble once properly levelled with an aftermarket spirit level check the meade level.....not even close.
Just one more thing once I'm all set up no drift etc etc my wedge's dec angle reads 36deg Perth is 32deg use the aftermarket wixey angle meter which is deadly accurate and it reads 31.8 deg so ummm ???
dont get me wrong I love the scope and its not a complaint all Im saying is that for me I was chasing my tail on polar alignment for months trusting the supplied bubble and compass, once I put more accurate measuring instruments in the loop everything was gravy no problems.
