Yes I did mention the FLT110 first in my post...

The quality of the lens design plays a big part in color correction, and yes, there are some very well corrected scopes with FLP-51.. Made by TBM/TEC/Takahashi and some other (very expensive) scopes..

A well made triplet will almost undoubtably beat a well made doublet, Just as a well made doublet will likely outperform a poorly designed triplet... Yes, the seemingly lesser scope can on occasion come out on top, but it can't be considered the norm.

Comparing 2 scopes designed by the same company, both doublets, 9 times out of 10 you can safely assume that the type of glass will have an impact on color correction..

I agree 100% on the comment about the FLT110, being of TMB design, and seeing the results other imagers are getting, its safe to say that it will outperform either the M110 or the M90.

If it were me I'd want to go to a star party and see both in action on some of my favourite targets - to do a side by side comparision. A decision based on the priase of each organisations marketing department's flair is a weak substitute for informed consideration.

Matthew is completely right... Nothing compares to real world experience.. and remember, reviews on the net are written by people, people whom may have different needs/wants and criterion to yourself... A lot of people said I'd be better off with a 10~12" newt rather than the 11" SCT, I however looked through a few, and decided that for my needs, the longer F/L was more of a plus than a negative that so many reviews mentioned.. They also never mentioned that because this scope is about 1/2~1/3 the length of an equal aperture newtonian, that my mount would handle it much better despite the weight being the same... Things like whether or not a scope will suit your indivual style of imaging/observing, your current equipment or your lifting/transport capabilities are things that only ONLY!! you can decide... No review will tell you if you can lift a scope, they can tell you the weight, and if its awkward, but is it too awkward? or is the reviewer a 60kg 6ft tall gangled creature who has trouble lifting a bowl of weet-bix?

Matthew is spot on... Go and have a look at a few scopes both in stores, and if possible at star parties to get the best idea of what suits you..

I can not imagine anything worse than buying a 2k~3k scope, then finding out in a couple of weeks that its not for you...

I'll ask around and see who has anything similar to what I'm looking at. I have an LX90, so I can already guess what a SCT will be like, and a 10in reflector is what I want to replace as it has problems, so I know what one of those is like also. I'm just not really keen on refractors and if I do get one as a "necessary evil" for wide field, I only wanna spend 2k plus an electric focuser and I really, really hate blue fringing around bright objects and stars. I know it can be removed with software, but sometimes you can glimpse the result. Thanks for all your help, guys!!

I think a main difference with imaging in mind is that SCT's/Refractos do not have a spider to hold the secondary in place. hence you don't have diffraction spikes. Newts have these, if you like them then happy days, if you don't like these then your choice is narrowed.

Thats my 2 bob worth.
