Is it possible to remove the dove tail on the Skywatcher 127/1500 ? Or will you wind up with two nuts inside the tube? I ask because if I can remove it I can use tuberings. Which makes it much easier on my 130SLT mount.

The 127mak does not have nuts inside.

Champagne color 150 180 doesn't have nut too.

Black diamond 180 are improved with washers on the inside to increase contact area.

Not sure if you are doing this to put the focuser in a better position, but I lossened the rear screws, turned the rear cell so that the focuser knob is in a better location when mounting on the right, and then tightened the screws again.  I my case collimation stayed good, however you may need to tweak it (which is not hard). I then used a RACI finder and a Telrad on top.

It's not that hard.  You just have to make sure that the rubber o-ring between the rear cell and tube remains in place properly because it can shift a bit when you rotate the tube. And if it does, no big deal, you just put it back.   If you want, PM me and I will send you the collimation instructions I prepared for my scope in a small word doc.  

 

You will love that scope.  It seems to be the same as mine (Skywatcher). The optics are great and the views very Sharp.

Great. I have the 130SLT and love it. But for the moon and planets this one might be better. That way I have both. Depending on what's to see. And when it comes to tinkering I will almost certainly come for help. First things first... trying to sleep... we allready have clouds for weeks, maybe this buy will clear things up a bit.

Ordered. So it will be in on monday. And guess what accuweather predicts? Thunderstorms. Which will be, to be honest, very very welcome. No rain whatsoever this summer and everything looks mummified.

AAArrggHHHH that took a while...

 

I ordered a SkyWatcher 127/1500 2". However they send the 1,25 ".

Now they say they are the same tubes, but the 2" has a 2" diagonal, but the tube and connection is the same.

If I send the 1,25 diagonal back they´ll send a 2". But I don´t feel that´s ok.

But when I look at the specs at the website it says everything is 2". (http://skywatcher.co...hp?cat=15&id=72).

So does anyone knows these two tubes and can tell me if they are bullsh*tt*ng me.

If I look at pictures I would swear they were different.

 

I have the tube here, and am in discussion with them right now. Any help would help.

The scopes should be the same.  Does yours have a 2" visual back on it? If so they just included the wrong diagonal, otherwise they will also need to send you the 2" VB.

From what I understood is that the 2" version is a scope specially adapted for 2". Not a 1.25 with an adaptor so you can you use 2". Anyway, sending it back, and on the hunt again for the one that's advertised.

It is actually a 1.25" opening with a 2" adapter. They cannot make a 2" opening with the 127 otherwise the central obstruction ( ie secondary mirror) would be too big. But don't worry, the view will still be amazing with a 2" EP. I use a 2", 32mm 70 degree EP in mine and it is stunning. I don't notice any vigneting at the edges.

Great! I'll take their offer then to replace the diagonal. I also have a 32mm 70degrees 2" and it'a blast in my 130slt. A huge bucket of stars.
