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!

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.

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.

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. @lex Post Extras:       mariobmd professor emeritus Reged: 07/14/07 Loc: Jackson, Ohio Re: Choose my setup new!!

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. Post Extras:       mmalik Carpal Tunnel Reged: 01/13/12 Loc: USA Re: Choose my setup new!!

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."

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. @lex Post Extras:       SANDRO78 super member Reged: 06/12/12 Loc: RP PARIS Re: Choose my setup new!!
