EQ5 GOTO alignment solved?

I think I have the solution, rather silly.

Tonight I did a rough polar align and slewed to acrux, which it missed by over 5 degrees, but RA looked close. Slewed to Alpha Centauri, moved the scope to physically point to Alpha C. and then slewed to acrux, which it found OK.

I've noticed that the balance of the scope on the mount is not good, due to the grease stopping the scope from rotating when I release the clutches when I try to balance the scope. So I suspect that a combination of not tightening up the clutches far enough and the scope being out of balance was causing the alignment to go completely out of wack.

Looks like I'll be cleaning out the grease using Astroboy's guide...

Can you point me to Astroboy's guide Peter? I can't seem to locate it either here or elseware.

The SVP/cg5/eq5 are all similar inside.

EQ5 GOTO update

Well,
seems I didn't find the solution. I've contacted Skywatcher technical support and they sent me some real interesting instructions which they advise will solve the problem.

The solution:

1) polar align, point scope to south pole, power on
2) Do one star alignment. use the controls to slew to the star
3) Press enter
4) Turn power off
5) polar align, point scope to south pole, power on
6) One/two/three star alignment should work


Now as soon as the clouds clear, I'll try it!

Peter are you sure they said to power off without first parking the drive? (step 4)

Hi Peter
looking at your last month problems you reminded me of my owns from last week. I bought EQ5 SkyWatcher with SynScan - polar scope -to be able to look throu it move RA axis of mount(tube) 90 degree. To do lower than 33 degrees you HAVE TO take out locking bar ( at the front), nothing wrong will happend. Inspite of correct alligmentand all coordintes and time, my GOTO was poiting telescope to wrong directions. After returning back to the shop the problem was in controller itself. Preset to Northern Hemosph. without maniual possibility of changing. I simply got new controller which works perfectly. So many days I've spent re-doing things, thinking I'm doing something wrong. So much waisted time, so I want for everybody else to know what the resolution to that problem might be.
