Notes on Aligning a Celestron Goto Telescope

In specimen anyone else is searching for this, here are some of my observations on getting a edible alignment from a Celestron NexStar  telescope. It's actually not hard at all if you know the tricks. There's a lot of careful information about these telescopes on Michael Swanson's NexStar Situation, and the guides there are worth a read. But here's the 60 approve of cheat sheet.
align.gif1. Get a decent, penny-pinching bullseye level -- the telescope comes with one but it's wee, and stupidly has a thick, uneven sticker on the bottom. Put the open on the top of the battery door and quickly unalterable tripod.
2. Make sure the OTA (the telescope part) is mounted on the arm almost, but not wholly all the way towards the back end of the mounting bracket. About 2 cm of the bracket is evident towards the back of the mounting arm.
3. Turn on, and enter the unearthing and time. Get pretty close with the position (i.e. just "Palo Alto, CA" is good). Be exact with the time -- one one sec off seems to cause problems.
4. Align on the first important -- I alway use Polaris because I can. Put together sure the last (fine) adjustment is always UP and to the Speedily when viewed from within the viewfinder. This matches how my spread slews to a target. If you overshoot, go back to the crop left quadrant and try again.
5. Repeat for a relocate star, which should be widely spaced from the first.
6. Repetition for third star.
7. Profit!
