Now I knwo this is going to sound daft but I have forgotten how to

adjust the polar alignment of my HGM200. It is slightly off in

altitude so needs moving higher, northwards.



Looking at the base of the mount the E-W adjustments are made in a

push-pull arrangment using the two silver coloured knobs. No problems.



But for altitude, I thought you use the large plastic black knob and

screw in to raise, and out to lower. When I tried it, it seemd to

just do E-W movements. What have I forgotten, with no manual, and it

being a long time since I did it I have forgotten. Do I need to

tighten or loosen something.



The E-W adjusters are slightly loose, is that causing the problems???



It is clear here in the UK and I would like to get the alignment done

soon as we have a full moon.

Hi George,



Before the large black knob will raise or lower the mount you must

first loosen the large allen headed bolts located on either side of

it. You will need a big allen key to fit these bolts.



Also, make sure all the bolts are tight prior to imaging(including

the E-W adjusters) to ensure the the mount will not move. Be careful

because you will find that as you tighten them the alignment of the

mount changes slightly.



Good Luck, Richard
