20 arc-second pointing

After trolling around down near the Teapot this morning, I slewed to M57 and took these shots.

The screen-shot on the left is is to demonstrate the pointing capability of the ParamountMX mount. This is after (on a previous night) a 250 point modeling run followed by a 20 point run (to get in another meridian flip). On a later evening, a 20 point re-calibration was done.

The screen on the right is to demonstrate centering the target (M57) by (1) performing an image link; (2)synching on the image linked photo center; (3) then re-slewing to the target object.
