5.5. Align

This function is used for aligning the telescope. The system provides three alignment methods: “One Star Align”, “Two Star Align” and “Three Star Align”. The mount has to be at Zero Position before perform any star alignment.

5.5.1. One Star Alignment

Press MENU button and select “Align”. Select “One Star Align” and press ENTER. A list of alignment stars that are above the horizon is computed based on your local time and location. With the mount at the “Zero Position,” use ▲ and ▼ buttons to select a star and press ENTER. Center the target in your eyepiece using arrow key. Press ENTER when finished. If your mount is well set up and polar aligned, one star alignment should be sufficient for good GOTO accuracy. To increase the accuracy you may choose to do two star alignment.

5.5.2. Two Star Alignment

Two star alignment will increase the GOTO accuracy of the mount. Two star alignment requires a wider view of the sky, since the two align stars need to be far apart. Press MENU button and select “Align”. Select “Two Star Align” in the align menu. A list of alignment stars that are above the horizon is computed based on your local time and location. With the mount is at the “Zero Position,” use ▲ and ▼ buttons to select first alignment star and press ENTER. Center the target in your eyepiece using arrow key. Press ENTER when finished. The hand controller will prompt you to choose the second star. If the star you choose is too close to the first one, the system will let you choose another one. When you are aligned with the second star, the two star alignment is finished. You can reject the suggested star if it is blocked by a tree or other obstruction.

After the two-star alignment, a pointing error between the R.A. axis and the polar axis will be recorded. This number can be used to fine tune the R.A. axis.
