Help! 130GT - Dumb Newbie
Posted 01 February 2004 - 08:36 PM
Now, the really stupid thing is that in trying to fix the darn thing, all the flat screws are now off (don't ask). Looks like the main mirror is just loosely laying in the back of the tube.
So, how do I go about reassemling the scope? There are three phillips-head screws on the sides of the tube, but I'm not sure if I should take those apart to access the mirror and reassmble the main mirror.
Ok, folks. No laughing, please. :o Please, just help me out the hole I just dug for myself.
P.S. Amazon kept saying that the "NexStar User Guide" wouldn't be shipping for another four weeks...but as soon as I came online to ask for help, Amazon notified me that the book shipped yesterday! I should have waited

You might also try just loosening one or two of the lean screws to see if the mirror tilts far enough for you to reconnect one of the collimation screws.

Whew! Thanks. We took the back assembly off by taking out the phillip-head screws and that made it easy to reassemble. In hind-sight (now that it's all back together again), I'm glad I messed up because I see how it works.
Thanks for verifying my thoughts that the phillips-head screws held the back assembly onto the tube.
Now, I'll go back to my first attempt at collimating...much, much more gingerly.

I guess I'll be referring back to this thread when I get my 130GT. It's due to be on my doorstep this Friday. I feel like a kid waiting for Christmas!

Congratulations! It's great to have another 130GT person in the group! I hope you have better viewing conditions with your scope than I have had with mine.
My 130 was an Xmas present...and it's now Feb. 2nd and I still have not had one night without heavy clouds. The moon was visible for about 10 minutes a few weeks ago and we ran around with the scope trying to view it. We did, for about one minute. It was amazing -- we saw craters -- and that was through tinted windows with the scope straight out of the box and just picking a lens at random. Alas, it's snowing tonight (again) and I'm still waiting for my first "partially" cloudy night.
It's been quite cold in NJ. Have you had any clear nights? It must be quite cold for night viewing right now. Puxitawny Phil isn't optimistic about warm weather anytime soon!

just my 2 cents.

As a new 130 user, have you checked out the following sites?
The nextar and baby nexstar Yahoo groups?

My idiocy was quite apparent when I did access the primary mirror to discover that Celestron had already marked the center spot with a binder reinforcer. I didn't need to do that step at all! I just didn't know what I was looking at through the Chesire Collimator.
I still don't understand exactly how to align the secondary mirror. I'm hoping the NexStar book will make the process clearer. There's not much to tweak, but I just want to learn how to do it.

I downloaded the 130's manual and the info in it is sparse, indeed. Looks like I'm going to order the "NexStar User Guide" soon. I'm a rank newbie, myself, although I did some unguided poking around with a cheap refractor when I was in junior high.
Yeah, it's been frigid and nasty here in NJ as of late. The way my luck holds, there won't be any good conditions for weeks after I get my scope Oh, well, it will give me some time to devour as much background reading as I can handle.

Collimation should be a little easier in the 130, as it doesn't have the internal corrector(barlow) lens in the focuser as does the 114.

My 130GT arrived about 2 hours ago. Forecast: Rain
I must admit that I seem to have received quite a bit of bang for my buck. I must also admit that I had to do some head scratching trying to figure out how the mount would ever take the telescope anywhere near zenith. Then I realized that they had the OT clamped in backwards...for packing purposes, I guess.
I'm very excited as this is a HUGE step up from my Costco Bushnell Voyager Newt. If only the rain would go away before Orion goes away!!

It's just what I needed!
Posted 03 February 2004 - 09:23 PM
Yup, you convinced me....the "NexStar User's Guide" will be ordered here. You're three steps ahead of me here with the 130. I think it will be GREAT to compare notes as we go! I should have my 130 this Friday!
Are we there yet?

The scope is assembled and it works. I tried a dummy alignment inside the house just to watch it try to do it's thing. I borrowed a friend's GPS receiver, so I have an accurate present position (my back deck) to put in for the alignment...maybe tonight!

I was out last night, well out for 20 min in for 20 min...you know to warm up!!
Posted 08 February 2004 - 04:38 PM
I'm DETERMINED! It's a brand new scope and I'm dying to get it out for longer than a 20 minute tease!
Cold or not, I'm out there!
