Thanks, Tom. I already have both.

Doesn't make it any easier to match pixel pitch to FL thought. Mutliple CCDs are beyond my ability to support this hobby. One camera has to do!

Well, it's here.
Picture is just for show . . . no intention of actually mounting an FSQ106 atop the TOA-150 like this.
I gott'a be the only person in the world with these OTAs and absolutely not a mount in sight to put 'em on.

C'mon, A-P! Start shipping those AP1100s!!

Hi,

I can't give any advise on 150old vs 130new. However, I have some information for you about 150's focuser.

I have a TOA150, with the new focuser. I have used it for roughly 3 years. Just to show you that I am at least a semi-serious user, here are some pictures I took with this telescope:
http://www3.asiaa.sinica.edu.tw/~whwang/gallery/picutres/M101.htm
http://www3.asiaa.sinica.edu.tw/~whwang/gallery/picutres/NGC7000.htm
http://www3.asiaa.sinica.edu.tw/~whwang/gallery/picutres/Eta_Car_2012.htm

Now, on the focuser, to my surprise, this new version focuser is not as good as the old one. Last year, I was evaluating its capability to hold a heavy camera (FLI 16803 Pro plus a large filter wheel). I found that there is a clear tilt of the focuser once it is loaded with the heavy camera. The tilt is so large that I can see it with my eye (no fancy measurements, just by eyes I can see it). A friend who works for a local TAK dealer told me that it is common for the new focuser, and the old one is better. I couldn't believe him. So I found an old TOA150 and tested it. And he was right, the old focuser is more solid than the new one. I cannot guarantee that there is absolutely no tilt with the old focuser, but it is totally clear to me that the old one works better in terms of holding heavy cameras. I asked how much it will cost to get an old TAK focuser, and it is very expansive. So I just ordered a Feather Touch Focuser, and I am still waiting for its arrival.

So, please don't consider the old focuser a disadvantage. It may not be as good as the FTF, but it is better than the one on a new TOA150.

Cheers,
Wei-Hao

Hi Wei-Hao:

Beautiful images! Especially Eta Car as we don't get to see it here up north.

Certainly your observations about the old vs the new "Type B" focuser are a revelation. My own camera is unlikely to tax either but I may not have such a light camera for ever.

No input here on the 150 focuser (I own the 130) but wow, nice images! Typical TOA style beautiful color and high contrast!
I have to say, I bought the TOA130 because I couldn't get the AP130 right away....now I am not sure that I will ever give up the TOA, even when my name comes up on the AP list.

I can't imagine why Tak can't fix this problem on a 11K scope, My cheap AR had that prob. but I started tightening the little hex key screws around the focuser, fixed it right up. you would thing the tak would have something similar.

Hi Andy,
Excellent scope. I suspect you will be tickled with its performance.

I have the TOA-150 and I mounted my FSQ-106ED on top of the TOA-150.
