EQ6 Pro altitude - to loosen or not to loosen?
      #3299304 - 08/28/09 06:08 AM

OK usual problem: very stiff - can't move by hand, bottom bolt slightly warped, going to buy replacement stainless steel bolts.

My EQ6 is pier mounted in an observatory so once it is aligned that is it until I move house - I guess it needs to be checked once in a while. So stiff could help keep everything all locked down tight - but still the initial alignement could be a real pain.

I really don't want to destroy the end caps unless I really have to. Guess I will wait for the new bolts and then try first.

Interested in preference: stiff + new bolts or loose + new bolts.

Surprisingly my EQ6 which is about eight years old doesn't have this problem. It is permanently pier mounted and I replaced the alt screws with brass to keep the wear on the actual castings to a minimum should the need for an adjustment arise.

Suggest that you remove the counterweights, elevate past your latitude, then restore the counterweights and gradually wind down until you are happy, then lock the thing up. Particularly if drift aligning its the way to go, let gravity be your friend.

Given that your mount is an a permanent pier its no big issue if it takes hours or days to get your alignment as you want. You will only ever need to do this once, unless, as you say, you move house.
