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 Vincent FRANCE

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. - charles sinsofsky author: Astro-Physics DigitalSky Voice and the Hand-controller for the Goto mount. www.digitalskyvoice.com aka: strfire@...

Hello again

It is just that the horizontally of tripods (or else) isn't important when we use AP Polar Axis Finder Scope??? Bye Vincent
