Hy has all!
I think of changing my setup, my choice it carry between the TOA 130 and the TEC 140 by knowing that I possede a CCD QSI540 WSG.
I shall replace also my 80ED by the FSQ85ED.
Thank you in advance!

Bye @lex

I would suggest replacing your 80ED with FSQ-106EDXIII....

Looking at your mount setup, it should be able to handle either one of the scopes you mention nicely; my choice would be TEC 140; flexure being the concern with TOA 130 focuser. Thx

The advantage of the TOA-130 is the availability of dedicated reducers. What f/ratio would you like to achieve?

I have a QSI-583wsg. Flexure has not been an issue with the 4" focuser on my TOA-130. I did make a minor adjustment to the focuser and the CAA before first light.

Hello, thank you for your answers.
I wanted to go towards the 85EDX for a wider field, without having has to change my CCD and to buy a reducer of focal.

As regards the comparison of the TEC and the TOA, for the moment, I have two different notices thus I thinks that I am going to wait for other answers, it will allow me to have several notices.

Thank you has you.

I use a TOA130NFB and a QSI583ws. I use the 67 flattener. For me the TOA is an imager's scope. Dedicated flattener, reducer and extender. The imaging accessories are readily available. I have used all three accessories with success. I now have a FSQ85 and the reducer to compliment the TOA but have not yet had first light due to weather. IMO, the TOA130 is the better choice. The B focuser is very robust, no sag! You can check out my web site for images with the TOA.

FSQ-106EDXIII has a wide field of view and you shouldn't require a reducer with it.

A quote... "By adding a second doublet inside the tube, the optical wave front can be optimized to remove any astigmatism - this in turn acts as a field flattener."

Thank you mmalik
It is true that this evolution of 106 is interesting, but its price is also more brought up, the field is very too big.
I shall like having a field equal has that of one 85 with a reducer, because certain Nebulas are very vast and I shall like avoiding losing too much time has to make mozaics.
