5.3.6.1  RA/DEC Display 
Upon selecting "RA/DEC Display," Gemini switches to the Telescope Control Mode and 
displays the telescope's current RA and Dec. coordinates.  Then, while observing the 
display, you can move the telescope to a new position via the RA and DEC directional 
buttons.  As the telescope moves, the display will continuously change to show the new 
position. 
5.3.6.2  Enter RA/DEC 
This command allows you to enter the RA and Dec. coordinate for a point in the sky.  As 
in the previous menu item, selecting "Enter RA/DEC" displays the telescope's current RA 
and Dec. coordinates.  You can now enter a new set of coordinates by changing the 
displayed numbers. 
To enter new coordinates, navigate from digit to digit with the RA buttons and change 
their values with the Dec. buttons.  After you have completed the entry, navigate to the 
far right digit and press the RA+ button.  The new coordinates will be stored as a selected 
object that you can slew to via Gemini's GoTo function (provided the object is above the 
horizon). If Setup >Coordinate Epoch >Epoch J2000.0 was selected, the input 
coordinates are interpreted as referring to the IAU standard epoch J2000.0, and are 
precessed to the equinox of the date. As when selecting catalog objects, entering RA and 
Dec. coordinates with this function causes Gemini to display the object's hour angle (in 
minutes) and elevation (in degrees). 
5.3.6.3  Set Bookmark #n 
This menu item allows you to store as retrievable bookmarks, the coordinate position of 
up to 10 objects.  To mark the first object, center it in the telescope's field of view and 
execute "RA/DEC Coordnt
Set Bookmark #0," where 0 is the number of the first 
Bookmark.  The process can be repeated 9 more times for Bookmarks #1 to #9.  Any 
Bookmark can be overwritten by scrolling to it with the DEC buttons before setting the 
new Bookmark.   
Note:
 The bookmark does not replace the selected object, so slewing to the 
bookmarked position can only be done by executing the "GoTo Bookmark #n" menu 
item. 
5.3.6.4  GoTo Bookmark #n 
To GoTo the object at stored Bookmark #n (where n is an integer from 0 to 9), merely 
execute "RA/DEC Coordnt
GoTo Bookmark #n."  This function is exceedingly useful
