It will certainly give a widefield of view. It will however suffer quite a bit from chromatic abberation (false colour) when viewing anything bright like the moon or planets. Are you planning on using it for visual, imaging, DSO, planets or lunar?
I do not really know anything or have experience of the Ioptron ZEQ25GT mount. It seems that it is a bit more substantial than a SW EQ3 Pro but at a substantially greater price. In fact it seems that it is really only £100 less than a SW NEQ6 SynTrek.

Are you looking to buy the scope and mount as a package? Of the prices I have seen for each item - scope £465, Mount £849 - giving a total of £1314. In my opinion that is a significant amount of money.

It is very hard to suggest what else to consider without knowing what you hope to do with it.

Andy,
There is an excellent review of the IOptron Z25-mount in next month's March Sky and Telescope magazine (not out in the shops yet). Broadly it seems a good mount and being light is easy to carry out. However, they only recommend it for up to 4-inch refractors - there's more to what a mount can carry than just a payload suggestion.
If you are going the refractor route (sensible for imaging) then several members have got Apos (more suitable than achromats) on a variety of mounts so it would be worth asking around at the next meeting.

I want the mount for it's portability and the scope for galaxies, star clusters and nebula's the payload capacity is 27lb and with the ota being 4.5-9 kgs i thought that would be suffice.
just watched this video https://www.youtube.com/watch?v=_cIOTROXEpQ and this one

A lot of money for what appears to be a Meade with a different sticker on it. Have a look at Altair Astro - several members have scopes from this supplier and so far they have all been excellent ones. Our society's own 80mm is from them and when the flattener is added it is a quadruplet!

Had a look at all the different 80mm triplet scopes, & they all have a similar specs using the
FPL-53 elements and 1:10 dual focuser. the acension is £50.00 cheaper than the Meade & £100.00 cheaper than the altair wave 80mm, skywatcher & vixen and others are near the £1000.00 mark.
The other thing was one mentioned strehl Numbers ( acension ) and the altair (abbe ) did'nt have a clue no good at maths I also have read lots of reviews on triplets & there some good & some bad, hence the me asking the question on the acension :?

P.S thanks for taking the time to answer
