Gemini Users Manual 70

For example, setting the GoTo limit to 95 degrees means that a GoTo command to any

object 5 degrees or further west of the meridian will cause Gemini to point to this object

with the telescope tube on the east side of the mount (doing a meridian flip if needed).

The telescope will still track an object past this point if the tube is on the west side of the

mount, but once an object has passed the GoTo limit, a subsequent GoTo command to

this object will force a meridian flip.

A value of 90 sets the GoTo limit to the meridian itself; meaning that a GoTo command

to any object west of the meridian will force the telescope to the east side of the mount.

The default value of zero means that the GoTo limit is set 2.5 degrees east of the western

safety limit.

Note: Use caution when setting the GoTo limit to values between 1 and 89 degrees.

Such values would indicate points east of the meridian, and would mean that Gemini

would try to point to objects between the GoTo limit (now in the eastern hemisphere) and

the meridian with the telescope tube on the east side of the mount. It is possible that such

objects would be unreachable without violating the eastern safety limit. Attempts to

GoTo such objects in this situation would result in the telescope not moving, and

“*Interrupted*” being displayed on the hand controller.

5.3.10.2.7 Set Home Posit. (Set Home Position)

This menu item allows you to set a Home Position for the telescope that is different from

its Startup (CWD) Position default. This is the position to which the telescope will slew

when "Park Mount!→Park @Home Pos!" is executed from the "QuickMenu" (see this

Chapter, section 5.4)

If not expressly changed, the Home Position defaults to the Startup (CWD) Position.

Either position can be slewed to from the “QuickMenu.”

5.3.10.2.8 {Pointing Model}

• Undo Last Align

• Store Model #<n>

• Reload Model #<n>

The Pointing Model menu item is available only after you have performed at least one

Additional Align. The first submenu item allows you to remove the data of the last

Additional Align from the modeling data set, undoing the last alignment. This is useful if

you misidentified an alignment star. The other submenu items allow you to store and

reload, as the current model, one of 10 permanently stored models. This function is

especially useful while testing several models or while using several OTAs from the

same permanently setup mount.
