Gemini Users Manual 38
• Cold Start
• Warm Start
• Warm Restart
When the Gemini is powered up for the first time or after a CMOS reset, "Cold Start" is
the only menu choice since there was no valid model in memory. Once a model has been
established, subsequent power-ups will add "Warm Start" and "Warm Restart" to the
startup menu.
"Cold Start" is the "start-from-scratch" startup choice because it deletes all previously
established model parameters of the current model derived from previous alignments. It
is the startup mode that must be used anytime the mount has been moved from its
previous polar-aligned position.
Upon selecting "Cold Start,” Gemini allows you to change the UTC Date/Time,
Longitude, and Latitude. You should enter these parameters at this point unless they are
still valid from a previous observation, or were provided by a GPS receiver that was
connected to the Gemini when it was powered on.
Assuming Gemini was powered on with the telescope in Startup Position, you can easily
find a first alignment star using the Align Telescope→GoTo Bright Star command which
displays a list of well-known bright stars currently above the horizon and slews to the
selected star. Alternatively, you can select a star by navigating to the "Databases" menu,
selecting a star from the Bright Star Catalog, and performing a GoTo operation. In either
case, you should then center the star in the telescope's field of view, and select the
“Align→Synchronize” menu item. Synchronizing on this object constitutes the initial
star alignment in the process of building a pointing model. Subsequent star alignments
can then be performed one at a time by slewing (via GoTo) to other Bright Stars,
centering, and executing "Additional Align."
“Warm Start” is used to tell Gemini that the mount itself has not been moved since it was
powered down, but the clutches were loosened and the telescope was moved by hand.
Gemini keeps all of the modeling parameters from the previous session, but resets its
assumed position to the startup position (counterweight down and OTA pointing to the
pole). For this reason, you must make sure you have moved the telescope to the Startup
Position before selecting “Warm Start.”
Finally, if the Gemini is subsequently powered on without the telescope or mount having
been moved in any way since the last observation, "Warm Restart" is the startup mode of
choice, and the telescope is immediately ready for use. All modeling parameters and
positional information is retained from the previous session. This startup mode is most
useful for permanent installations, multi-night star parties, and daylight observing.
IMPORTANT: If you use the “Setup” menu to change Gemini's Geographic Location
or UTC Date/Time immediately after a Cold Start, the new values are not used to set the
initial pointing model or calculate Local Time until Gemini is powered off, powered back
