Hi mpopo,
Looks like so far you have not got a very informative answer to your question about the difference between the 85mm and the 95mm objective module, and unfortunately even some dodgy statements from Jason.
I attach a link to a table by Swarovski which will give you some factual information regarding magnification range, field of view, apparent field of view, weight etc when used with the ATX or STX eyepiece module.
You will see that the magnification range with the 85 mm objective module is 25-60x with a field of view ranging between 41m-23 m/1000m.
Therefore at lowest mag it provides a wider field of view (41m/1000m) than the 95 mm module (35m/1000m), which has a magnification range of 30-70x and a field of view ranging from 35m-19m/1000m.
This puts the 85 mm module at an advantage when it comes to first acquiring your target, if you are scanning or when observing at closer range.
The apparent field of view is the same for both modules (57-71 degrees).
The weight difference is 240 grams. (Advantage 85 mm module)
The advantages of the 95 mm module are:
1) bigger max magnification of 70x (if you need that)
2) it gathers more light
I have no personal experience with the ATS scopes but I believe that they are fine instruments too. Obviously 80 mm gathers a little less light again. They have a choice of 2 different eye pieces: a 20-60x and a 25-50x wide angle.
Here's a link to a table with their specs:
Hope that helps!
Not true, see above

? How exactly is that different between the 85 and the 95 mm module please?
and I get to see more details with my 43 years old eyes (using STX and BTX modules) with the 95mm when I compared with friend's 85mm during dusk and dawn in the rainforest where I usually lead birding tours
