Just ordered a Z12

Just bought a Z12 can't wait for it to get here. I do need some advice on what to get for a good collimating tool though.

Congrats on the 12" scope. I have a XX12 and DSOs really come alive at this aperture.

For collimation I use CatsEye tools. There is no substitute for precise collimation and cool down if you want to get the most from your scope. Howie Glatter tools are very nice as well. His combo of a laser and a TuBlug make collimating the primary mirror very easy. I have a 1.25" TuBlug which does a great job on my 6" dob.

Congrats, on your Z12. I have one too. It gives great views and has great motions. I have the Glatter tools also 2 inch laser and tublug. But, for the longest I used the supplied laser after collimating it it worked fine. I also used a barlow with the laser for primary mirror adjustment. Also have a celestron sight tube to line up the secondary under focuser.

First things I would add would be a telrad, something comfortable to sit on and star chart.
Be prepared to be wowed if you are going from your c6 to a 12. THX.

i had one about 6 months ago, for the $ i dont think you can beat it. its very well constructed and the views are great! i sold it shortly after because i needed something with goto or pushto because my sky isn't dark enough to star hop so i went with a orion 10" intelliscope. the 10" is much more manageable and not really a lot of difference in what you can see. take it to dark skies and it will blow your mind!!!!!!!!!!! good luck. donnie

Congratulations on your purchase of the Z12! I've owned one for over 3 years and enjoy using it. I second what someone else said about adding a Telrad plus its 4 inch riser mounting bracket. Really makes it easier to sight through.

The Glatter and the Catseye collimators are some of the best from what I hear. I use the Hotech 2 inch collimator plus I do a final check with a Cheshire sight tube collimating tool. Works for me!

When it comes to packing the most performance into the simplest, most easily used package, it's hard to beat the 12 inch F/5 GSO Dobsonian. There are a lot of fancier scopes out there but not many that will show you more..

As far as collimating tools. It one is careful to be sure the collimator is collimated and fits reasonably well in the focuser and if one uses the Barlowed-Laser technique of Nils Olof Carlin to adjust the primary mirror, then the stock laser is workable.

I am a big fan of Howie Glatter's collimators. I bought my first one about a dozen years ago, it's still going strong thought I have since added a 2 inch Howie Glatter. It's nice having a solid, reliable tool that is accurately made and needs no attention itself.

+1 on the Glatter Laser/Tublug. You'll never have to buy another...stay away from the cheap lasers....and the one that comes with the scope makes a great cat toy....but not much else.....

Another vote for the Glatter laser/tublug, and also consider getting Bob's Knobs or some other thumbscrews for the secondary mirror collimation...that way you can do away with using a screwdriver (they don't play well with primary mirrors).

Thanks for the advice guys. I was definitely planning on getting Bobs Knobs and upgrading the springs, from what I have heard the springs are kind of weak. I will also look into the Telrad. Thanks again guys!

Spend a little time on the "Mega-Mods for Zhumell" thread here in the Reflectors forum. It is full of good ideas and potential new friends.

here is what you need for Collimation. They have really good optics but keep going out of collimation. I solved it once and for all by going to the hardware store and getting some much heavier springs to go onto the mirror adjustment bolts. The stock ones are just not stiff enough!
After doing this I hardly EVER had to touch it again untill
the day I bought my 12" LX200!
The guy that bought it drove 4 hrs 1 way to get it.
He called me a few days later and even tho it was on its side bouncing in back he didn't even have to touch collimation!
