New member: AP GTO on Parallax mount

Mike Mah

Hello everybody,

I've just joined and I find these postings useful and informative. I
hope I can find help for some questions:

I have an AP155 EDFS with piggybacked Tak FSQ106 on a pier mounted
Parallax Series 125 with AP GTO v2.6. I have acquired these recently
and have only used this setup a few times, so that I have more
equipment than experience. I am waiting for an AP1200 mount, to which I
will move the AP155.

With mount level and after proper polar alignment using the Polaris
routine, I have noticed that occasionally objects are indicated as
below the horizon when they are not. For example, last night at about
9:30 pm the Orion Nebula was indicated to be below the horizon when it
was not, and I could goto Betelgeuse. Did I miss something in the
manual on the GTO keypad controller about the horizon?

When I tried to goto M81, I had to stop the slewing as the scope was
going to hit the pier. What angle does the safety zone number (0-20)
refer to? Degrees from the polar axis so that the safety zone is a cone
(or circle on the sky)? Is this then a blind spot that the scope can't
