When you are at Deneb for the second time, are you waiting till the

scope

reaches deneb, you then use the N,S,W,E buttons, to move the star

into the

center of the eyepiece, and then press MENU not GOTO, press the MENU

button

to auto-slew back to polaris. I will check the code if you can press

goto

and see what happens, but press MENU this will re-calibrate the

position of

deneb and then auto slew back to polaris where you will use alt/az

to set

the position of polaris, and then either 'next' to exit or goto to

re-select

another star or the same star. I use this method all the time for my

mounts

and it works fine.

Subject: [ap-gto] polar alignement,help

Hello (excuse me formy english)
I want to know if it is important to make the tripod horizontally

if i

want to use the polar scope.I have some problem with it.
The precision of my ap 900 gto isn't very good and i dont know

why.I

used the next method :
"i choose a star (for exemple deneb) and then manual move the

scope to

deneb. then once on deneb i use the telescope hand controller to
select
the star deneb in polar alignment mode and then auto slew it ot
polaris
after i select the star deneb. the scope will slew to polaris, at

this

time i use the alt/az only to center polaris as well as you can

then i

ask for re-calibrate and i choose deneb again the scope will now

auto

slew to deneb by itself, when you reach deneb, then i use the

'hand

controller
key n,e,w,s buttons center deneb in a medium power eyepiece, then
press
goto, the telescope will auto calibrate the new position of deneb

and

then
autoslew back to polaris, I repeat the same star 4 or 5 times,

then I

choose
another star a great deal of distance away from deneb and go

through

that
one 5 times and then I choose another star and do it 5 times and

then

I go
back deneb and the precision ISN'T VERY GOOD and i dont understand
why?
What is the problem (celestron 8",horizontally,orthogonality(i

have

the system astrophysics made for the celestron 8))
.
If someone could help me.
Bye
