Telescope tab (left) and the General tab (right).
Software Bisque strongly recommends that the Telescope >
Setup, Confirm Syncs option remains checked, since
accidentally clicking Sync instead of Map during a mapping run
is easy to do (especially late at night), and doing so ruins the
current TPoint model.
Session to Session Pointing Repeatability
In subsequent sessions, TheSky6 Professional Edition can accurately compute the current
equatorial and horizon coordinates of the telescope using the stored hour angle and
declination of the mount and the local sidereal time. In fact, the Paramount ME’s pointing
accuracy should be virtually identical from session to session.
As a test, you can verify the repeatability of the Paramount ME’s pointing accuracy:
1. Turn the mount off.
2. Turn the mount on.
3. Home the mount (this terminates communication between TheSky6 Professional
Edition and the Paramount ME).
4. From TheSky6 Professional Edition, click Telescope > Link > Establish. When you
re-establish the link with the mount, the telescope cross hairs appear at the home
position.
5. Slew the mount to the star you just synced on. The mount should slew back to this
star; that is, it should return to the same position in the eyepiece, video or CCD
detector. In practice, there may be small pointing errors that are introduced by
mirror flop, or slight differences in time, so the star may not be in exactly the same
position, but it should be very close.
Note that during the process of polar alignment, you will be required to “sync” the mount
several times (each time the mount is adjusted to a new altitude and/or azimuth). Once
the mount is sufficiently aligned with the celestial pole, you should not have to sync again
unless you change optical tube assembly or somehow change the telescope’s mounting.
