Why use Gemini.net ASCOM Driver with the Gemini-2 (or Gemini-1)?
- Gemini.net ASCOM Driver implements a standard ASCOM interface to contol telescope mounts. Many software packages support this ASCOM interface allowig you to try and use many of them. The ASCOM Driver is a convenience and, in many cases,
- If you need to share the connection to Gemini across two or more software packages, ASCOM is the only game in town today.
- Moreover, most astronomical software from small companies or independent developers use ASCOM to control astronomical equipment. This enables them to concentrate on one implementation that works across various equipment brands, and
avoids the cost of developing, testing, and supporting separate custom interfaces.
- You can control the mount via a Serial Cable, a USB connection or Ethernet (Preferred). (Gemini-1 supports serial only.)
- You can guide and control the mount using the same Ethernet cable.
- When a UDP Ethernet connection is used, the speed is extremely fast (faster that a USB connection) while minimizing the load on the computer.
- The Gemini.net ASCOM Driver allows multiple clients connected to the telescope at the same time. The Gemini.net ASCOM driver is a HUB.
- You can use other ASCOM drivers to control focusers, cameras, observatory, etc., and the Gemini.net ASCOM Driver to control the mount at the same time.
- Guiding through the ASCOM Gemini-2 Driver provides many advantages:
- The guiding is synchronous (two-way): Gemini-2 will acknowledge the guiding commands, something that is not possible when using the Guider ST-4 port.
- The Autoguider program can tell the mount how much to move, instead of sending fixed guide pulses via the ST-4 port. The Guider ST-4 port relies on an interrupt for the RA signal, but a timer for the DEC signal. This
means that DEC guiding pulses could be missed if they are too short. This problem does not exist when using the Ethernet port to guide.
- No guider cable is necessary, therefore almost any camera can be used to guide as long as you have a driver for the camera. The camera does not need a guider output plug.
- Less cables means less chances of a ground loop, which can cause possible damage to electronics. the Ethernet connector has a built in transformer that isolates its input and prevents ground loops.
