Why use the Gemini.net ASCOM Driver with the Gemini-2: (or Gemini-1)
- It provides a standard interface to the mount that many other software packages can use.
It's a convenience and in many cases a requirement.
- If you want to share the connection to Gemini across two or more software packages, ASCOM is the only game in town today.
- What's more, nearly all programs from small companies and authors require ASCOM because it makes it much easier
to develop for a wide variety of mounts (and cameras, and observatory equipment) without investing tens or
even hundreds of thousands of dollars to develop and test for each individual mount.
Small developers do not have the resources to do so. By developing their software for ASCOM,
they automatically provide support for all types of mounts without a major investment.
- It can be controlled via a Serial Cable, a USB connection
or Ethernet (Preferred). (Gemini-1 Serial Only.)
- Able not only control the mount with Ethernet, you can also guide
through the same cable.
- If UDP Ethernet connection is used. The speed is extremely fast,
even faster that an USB connection. Also the load on the computer is
- ASCOM Driver and Gemini.net ASCOM Driver provides for having many clients
connected to the telescope at the same time. The Gemini.net
ASCOM driver is a HUB.
- You can use ASCOM drivers along side the Gemin.net ASCOM
driver, such as for focusers, Camera's, and Observatory and
guiding programs. They will share information between
themselfs as needed.
- Guiding through the ASCOM Gemini-2 Driver provides many
- The guiding is Synchronous - which means two-way, the
Gemini-2 will acknowledge the guiding commands. Using the
Guider input this is not possible.
- The guide program can tell the mount how much to guide,
instead of a fixed guide pulse. The Guider input relies on an
interrupt for the RA signal, but a timer for the DEC, which
means DEC guiding pulses possibly can be missed if they are too
short. This problem does not exist when using the Ethernet port
to guide, using Pulse guiding.
- 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 guider output plug.
- Less cables means less chances of a ground loop, which can
cause possible damage to electronics. Ethernet has a built
in transformer to help isolate it's input, thus preventing
