Takahashi FSQ106ED v FSQ106EDX
« on: 18:01:34, 13 February, 2017 »
Just as I'd made a decision to go for the Takahashi FSQ106ED I saw the EDX!  I've read that the EDX is both optically and mechanically improved  but don't know the substance of this so would be grateful for some advice.  I would intend to initially use the scope with DSLR's but thinking seriously about moving to a CCD.

There have always been variations of the 106 and the newest one in the EDX line up is actually the EDX IV! Tak have made a few changes to the optics so if you can afford the EDXIV I would go for it.

Thanks Chris - it's cheaper than the ED - not much though!

I have just purchased a EDX IV, which at the time was the best part of a grand more than the ED.  The price of the ED has gone up a lot, I suspect so that TAK can delete the ED and streamline production IMHO. There are also differences in the back end so that the original reducer or extender can no longer be used. Naturally there are new replacements albeit at a cost.

I would also say that if going to image at f/3 an auto focuser is essential not just to have nice sharp stars but also make the most of the flat field which can be affected by less than perfect focusing.

The good news is all versions of the 106 work well and really it is your budget that will influence your selection. That said the main differences between the EDX IV and the ED are:

Improved optics
Different mechanical connection for reducer or extender as part of the new 4" focuser.
Addition of a CAA camera angle adjuster which replaces the captains wheel a more basic means of camera rotation.
Price
Both yield a 88 mm image circle
