    No experience with the vixen, but I did see one at a show . It's about as fast on its own as the FSQ106 is with a reducer, and apparently you can further reduce it to something like 300mm at f3.

    I guess one thing to consider is the camera you plan to use, and how it frames the sort of objects you want to image.

    One of the nice things with the fsq106 is that you can run it at f5 (native), f8 (with extender) or f3.x with the reducer, so you have a choice of focal lengths/image scales. It also makes an excellent scope for visual use.

    I have not directly used either scope, but some friends of mine purchased the Vixen and I helped them get set up. I am a Tak fan and personally would have gone for an FSQ as the Tak is a known performer with lots of available accessories to automate focusing, rotate the camera, etc. That said, the Vixen is a very nice scope, and they were able in pretty short order to get very nice pics from it. They were not using a very large chip (8300-based camera), so I didn't get to see how the Vixen worked with a very large sensor but I believe Tony Hallas did test this in his review and found that the Vixen did well. I also can't comment on whether the Vixen has better focus stability over temperature than the Tak. The helical focuser seemed to work well for manual focusing, though you need to be a bit careful of ring placement/tightening or it seems to bind a bit. Once they got ring placement down, focus action was very smooth. I don't know if anyone is yet marketing an electronic focusing solution for the Vixen, but seems like it shouldn't be difficult to do with a belt/motor and a mechanical fixture to hold everything in place.

    As Jerry points out, the Tak has a bit more flexibility (F8,F5,F3.x) and there are currently more off-the-shelf options/accessories available for the Tak. But I came away impressed by the Vixen, so really don't think you can go wrong with either choice for wide field imaging.

    I think I'm siding with the tak . Im not overly convinced with the helical focuser on the vixen and as you've kindly mentioned the tak has many accessories for focusing etc etc. Thanks for your help

    By the way - if you do end up going with the FSQ106, for native mode, you can use the fat (82mm?) extensions ahead of the 2" eyepiece holder instead of 2" extensions after it - or go 82mm to an 82mm camera adapter. For some reason, they don't show some of the possible combinations on the system chart.

    (And for some reason, European part numbers for things like extension tubes etc are different from the USA part numbers, which can be confusing if you're taking to someone using the other set ).

    I went for the fsq 85 in the end . A proven performer ! I also want to take it abroad which is partly the reason for the smaller scope . Thanks for input everyone
