Hi Uri,
In at the deep end... a bit. It took me a year to work out my HEQ5pro so here goes.
1. Look up IIS member Brendan Mitchell's web page. His set up of synta mounts is easy to read and understand.You can find him just about everywhere on the forum
2. Is the mount level before you use the inclinometer? It needs to be.I use that app too and it works .
3.11-12 degrees east is correct.
4. I always find that I have to move the mount physically with the alt and atz controls to get the first star centred in the alignment procedure, no matter how accurate I think I have done the set up.
5. The synta manual is next to useless, a lot of trial and error and asking questions is the way to do it.
So after all that last night( first for a while) I set up and got Acrux as my first star...so far so good, 2nd star I chose Sirius only to have the thing go way out
Acrux turned out to be Gacurx, I also need brain power which some days is sadly lacking.
Cheers Matt
