Vixen SkySensor 2000 Poor Alignment Issue

Matthew
Just got home so I will deal with your first reply first.
By the way, if you ever come to Perth I owe you a night on the town (as small as it is). I really appreciate your time and effort on this as it is driving me mad. The worst of it is, I sold my Celestron CG5 mount to get this one. The CG5 mount would not polar align and I finally got confirmation from Celestron that the CG5 had issues in the southern hemisphere. I fought with that mount for nearly 2 years as the polar alignment is critical for astrophotography. I am starting to have flashbacks of that mount. Sorry to ramble on.
1. It is the SkySensor 2000PC. Although it is not connected to a PC except for guiding. PC protocol LX200 and 9600 (although I did try all of them in frustration)
2. It is the version 2.10
3. Stars are selected from the hand controller (I usually select the stars from Stellarium prior to starting).
4. I have checked the gear ratio from the user guide (page 64 in my book) which says +36x144 +36x144. Interestingly when I changed these values to negative the motors slewed in the wrong direction on the first reference star so I reverted back to +.
5. The first reference star was Rigel Kent. The elevation was far too low and Dec probably 40 deg out. It did head in the right direction but no were near far enough.
6. I will take it out tonight and advise later on Antares as the first reference star.
7. Confirming internal encoder and I+400 +400
8. Also confirming the scope pointing East as you say.
9. The mount is levelled with spirit level and elevated approx 32 deg.
10. The mount is pointing South with lower end pointing North.
11. Motor key control exactly as you stated (up, down, left, right, North, South, East and West).

Thanks again

David
