Aligning a Celestron
Hi!
I have an entry-level Celestron telescope with an electronic controller. I believe that it is their '60' model. I took it out to take a gander at Mars during this time, and while I was setting it up, I started to tinker about with it's 'auto-alignment' funcitonality. I can not get auto-align to work worth a darn. Essentially, I point it north and level, and then I get asked a bunch of questions, date, time, city, state, etc. So I do this, and it is supposed to point to a 'bright star' - one visible by the naked eye. Not a chance. Even when I think I get it aligned right, I'll try my luck by using the keypad to select Polaris or the moon or some other star that is blindingly obvious. Well, when the thing stops moving, it may be pointing at my intended target if it was on some other planet, but on planet earth, it's pointing somewhere that is not even close to where it should be. It's obviously operator error. The question is what is the error? My idea of North (I live in New England) is either use a compass and grab magnetic north, or point the thing at the North star. Level - well I eyeball it and make sure that the tripod is pretty close, but I'm not out there with a bubble level or anything fancy like that. As far as plugging in the 'location', I've tried both city and state, as well as long and lat from a gps receiver. The scope itself is a long tube type - I've tried the collaring the scope both at the midsection, as well as at the hilt - directly in front of the viewing assembly. I'd really like some insight - if anyone can help, it would be greatly appreciated. -a. |

The scope might be working off the local standard time. L. |

Ends up that there is a 'bug' with the Celestron 60 series controllers that
were manufactured before 2001, I think. I found a fix at 'nexstarsite.com'. Essentially, when you first setup the software, it asks you what kind of scope you have. Well the settings for the 60 are way off base. This site had some funky code that you entered in - once done, the auto-align worked well. Just took a little research that's all. I was distressed to see that this was not mentioned anywhere on the official celestron site. "Llanzlan Klazmon The 15th" wrote in message 7.6... "Al Gartner" wrote in link.net: Hi!

Dito on the batt pack! The design could have been better engineered. I've
hung mine on the view finder. Also, I didn't like the way the try fit, the screw that holds it on, screws completely through the try. I've found that if you don't tread it completely through, and the rotate the screw along with the try it holds in place much better. I still have trouble with aligning; time will heal my ignorance. Hopefully. "pinkling" wrote in message ink.net...

It will make a difference. Also, check that power cord where it plugs into the mount, if it's loose, and it can be so loose that the plug literally falls out on it's own, use a small screwdriver to carefully bend that pin inside the hole--just a little--to put some friction on the plug when it's inserted, so it will stay in with good contact. Find a place to hang the battery pack so it rotates with the scope, and never puts pressure on the cord. Maybe none of this will help (although I think levelling will), but it can't hurt. Those plugs drive me nuts, that battery pack is really a **** poor design. Good luck, don't get discouraged. |

Okay, it looks like that not only can I not spell, I should stay away from
putting things together, with or without instructions! Each time I wrote "try," I meant to write "tray". The tray wasn't assemble correctly because I tried to fit it on the tripod below instead of above the bracket that it should be connected to. Somehow, I don't think this is going to imporve my viewing, but I do feel better about it. I purchased a David H. Levy's planisphere to help me locate and align my scope.

Hopefully. I got some velcro patches at the store, stuck one part on the battery pack (reinforced with a staple), and the other piece on the side of the mount. Wrap the wire from the pack around the mount a couple times to take up some of the slack, and plug it in.... it's out of the way, not hanging on the scope, and rides right along with any adjustments I make. A good solution for about a buck. "pinkling" wrote in message link.net...

Thanks, I'm glad I'm not the only one. The only problem now is that the
tripod will not fold without removing the tray first. "pinkling" wrote in message ink.net...

I figured out what you meant, because I did the same thing. I screwed the thing on--all the way through (looking nothing like the diagram in the manual), looked at it and thought "wtf? that can't be right!" I finally figured it out. Duh. |
