to go back to the previous digit. After you have entered the last digit, press the RA+
button again to finish entering the coordinates.
By default, Gemini assumes that any coordinates you enter are for the epoch of the
current date. However, you can change Gemini' s default epoch to J2000.0 using the
Setup
Coordinate Epoch
Epoch J2000.0 menu item. You can find more details on
this in chapter 5.
2.4.4.2 GoTo Operation
After an object has been selected (either from the internal catalogs or by entering its
coordinates) a new menu item appears: GoTo
currently selected object). Simply select this menu item to cause Gemini to slew to that
object. As the telescope approaches the object, it will ramp down from slew speed and
finish pointing at centering speed. When the GoTo is complete, the display will show
FINISHED. If you have correctly built a good pointing model, the object should be
within a few arc minutes of the center of the field of view. You can then center it using
the Hand Controller, and either Synchronize, or perform an Additional Align if you want
to continue to refine the pointing model.
2.4.4.3 Tracking
By default, Gemini will track at the sidereal rate. This should be sufficient for visually
observing nearly any object if you are roughly polar aligned, but the tracking can be
changed to other rates if desired. It is important to note that continuous tracking will
occur while in either the Menu Mode or the Telescope Control Mode.
2.5 Next Steps
The steps outlined above are sufficient to get you started and provide you with many
hours of observing pleasure. However, we have only scratched the surface of the
Gemini' s many capabilities. Please take some time to read through the rest of the manual
for information regarding such topics as:
