Re: Paramount ME vs. AP 1200GTO

The last time I was at your observatory, granted some time ago, I remember
the mount being center of the dome. Regardless, it's a ten foot dome. If
perfect pointing in an issue and you don't want to use the computer with any
modeling, what Roland is suggesting is fast and simple. I'm not sure what Ed
may have shown you last week, but his Polar alignment was done by me using
PoleAlignMax , PEM was programmed by using the included PemPro using
multiple guider cycles. Earlier issues with pointing was corrected when I
had him check his location setup in his hand controller, TheSky, ACP and
other programs he was using and making then identical in all programs. His
pointing is great now.

If you are thinking ME, how can you not use the computer to have T-Point
model active? After having just set up your Gemini G11, what is the rush to
get another mount other than the obvious move up in mounts?

If A-P had the product in stock and had the pointing model in the
hand controller, it would make this a very easy decision for me. I
already own/use TPoint from the computer, but having a pointing
model up and running on the hand controller would be great for
visual observing when the computer is turned off.
In an observatory situation you may never need a pointing model. You can set

up your scope to be quite orthogonal and well polar aligned, so the only
would come from atmospheric refraction, and that is already compensated in
the keypad. In my own observatory I have set up a 10" F14.6 Mak-Cass
permanently, and I never fail to place objects in the field of a medium
power eyepiece. I
don't ever use a pointing model and have never failed to find something
off the bat. It is a simple thing to place a bright star on the crosshair at

the beginning of the session, press Rcal and then zoom around the area with
pretty high precision. When I go to any other area of the sky, I first go to
bright star in the area, center it if it is off, and proceed to the object I

want to observe. It takes almost no time to do that. I have a green laser
on the scope, so I don't even have to look through the finder. The laser
is as accurate as any 1x finder system, and prevents craning my neck at odd
A pointing model is most useful for those mounts that need to be set up each

night fresh, but for a permanent setup it is not all that necessary (except
for those using teeny tiny chips with loooong scopes like C14s).
