hello

from the synscan manual of AZ EQ 5 mount,I read

quote

Now the screen will display “Point scope to ZZZ.Z’ TT.T’ ”, which means point the telescope
to the direction with an azimuth of ZZZ.Z degrees and an altitude of TT.T degrees.

unquote

assuming that I start from the north-level home position
will the screen display the updated actual azimuth and altitude values while the scope is manually slewing to the first star by the use of arrow keys ?

I don't do any of that. I park the scope vertically when done. When I next take it out I make sure it's level then do a 2-star alignment. Star 1 has to be manually aimed/centered (use a 10-12mm Reticle). Once you have star #1, choose star #2. The scope will slew to it. Center star #2 and alignment should report success. For more accuracy pick a couple objects around the sky and enter PAE data (pointing accuracy enhancement). Center the new object and hold the ESC for 2 seconds. Alignment is quick and easy and I can easily find what I want to view.

must you center the first star to the eye only ?
or
does the screen show you how close you are to the first star ?
otherwise what's the point of displaying azimuth ad elevation of the star ?

You must center the star in the eyepiece. That's part of the alignment process. Once the alignment process completes successfully the encoders take over and "count" the amount if movement to the next object. Equally important is getting your site programmed properly (date, time down to the second, gps location, and elevation). In my instruction manual (Orion XX12G with SynScan V5) it says polar alignment is not needed.

After alignment is complete the Alt/Az coordinates display properly.

I put these tips up as a suggestion with SynScan alignment. Again, I have an Orion scope but SynScan is SynScan....

Hmm good question.  The numbers change as you slew but I never checked to see how accurate they are on the first object.

Right now, if you can see it, pick Jupiter as your first object.  There is no mistaking that for some other bright star.

After the first star is aligned the next one is much closer.

 

Later on in the year Jupiter will not be at such an easy location to see.

 

I have the skwatcher AZ-gti with synscan hand controller.

Think of it this way. For the first object the controller says "aim here"...

When you center the first object in the EP you are basically telling the scope it is pointing to a specific coordinate.

That's why when you tell it what object 2 is it's close.

I find using a star instead of a planet (two star instead of brightest star) works better. Stars don't seem to move as fast through the FOV. Just know your alignment stars, especially the first.

I'll admit. First time seemed difficult but after a couple nights practice I can do an alignment in just a few short minutes.

hello

AZ-GTi is fitted with encoders same as AZ-EQ 5 so if you start slewing from north-level home position the "changing numbers " on the screen should be the
actual azimut and elevation of the scope
I suppose that accuracy mainly depends on the accuracy of the initial home position
even so such information is,in my opinion, of great help
I observe from my balcony in an Bortle 8-9
sometimes it is even hard to see the first star unless it is sirius..etc
if you are informed that the star is at least nearby you can easly center it with the finder
