Telescope Reviews: FUJINON 40X150ED first impressions

Last Thursday the Giant Fujis arrived after a long month of shipping, US clearance, shipping to Colombia, etc....
Fortunately everything arrived in perfect condition which made all the waiting (and worrying) worth.
Unfortunately, as with appears to happen with all new optics, weather is not contributing to any astronomical observation, but I'll be into it as soon as the clouds move over

Physically, the 25x150 and the 40x150 are almost exact, except for the 40x being 1.5cm shorter due to shorter eps.
Both have the same fast focus (meed less than a full ep turn to focus near to infinity), but the 40x is even faster (less turn distance from diopters).
The original mount (pedestal and tripod) is excellently built and steady as a rock, but is better suited for terrestrial observation. Since it was a whole package deal, I dont care much, but I'll be buying another Sirius P-mount unless Santa comes early whit a Starchair 3000

The binoculars are surprisingly easy to setup, a one man job. You only need another hand to carry the binoculars in their original case around. What a nice case! this one sure will not wear out easily or loose a handle, but at a U$1000 it is very expensive; if it where not included in the deal I would certainly had not buy it separately.
Now the optics. Very sharp! but no so different than the 25MT's. A bit of color is shown in some objects, but definitely less than in the MTs. Not 100% apos, but the ED correction is very important at this magnification, maybe that is the reason a 40x MT doesn't exist.
Their eye relief is shorter so I have to press my eyes to the eps to get the full FOV, but if I remove the winged style eyecups then it is far more comfortable. It is just a nose issue.
At this magnification, heat waves are more noticeable, so it makes detailed observation a bit harder at noon than at evening (beyond 3 or 4pm) on sunny days.
In terrestrial viewing, the 40x is sharp at least to 95% of the Fov, but this is a subjective estimation; star testing will tell more accurate readings in sharpness.
On Saturday night I had tree 10 to 15 minutes intervals of clear patches in the sky. Unfortunately, clouds get illumination from the city (Bogotá) so they act similarly as observing with a full moon, but where good enough to notice some things.
In the 25x, very dim stars appeared barely visible in the limits of their magnitude capacity (at the time, clearly diminished for the weather and illumination conditions..) When looking at the same target at 40x, those stars where considerably more clear (contrast), and others (not much and only in the 40% center), dimmer, appeared. This small test made me realize the investment was worth, since what I desire the most is to get a bit more detail of some DSO's, specially galaxies and dark dust over bright nebula.
Will I be able to see another component (E) of the trapezium??? who knows... will have to wait some months until Orion appears again... For the record, since EDJ mentioned the horse head nebula, I've observed it (barely) only twice under good conditions with the 25x150MT's, and at the same time I wasn't able to see it with the Chinese 150's, not at 25x, and barely at 39.5x, Fujinon Rocks!!
Is to be noted that 1.7º, different from what I thought first, are difficult to handle and this monsters do need a Telrad or similar, no wonder why Gordon R mentioned that this 40x was not used in fishing, 2.7º better for that purpose.
For now, I can conclude that the way I use them those two giants complement each other; the 25x for rich wide fields and the 40x to get more detail of some of my preferred DSO's, so I'm keeping both, specially because that way it is also easier and enjoyable to share views with the friends I observe. My other preferred binocular that I use as a finder, is the 10x42EL Swarovski, a perfect companion for the big Fujis; Those, a coupe friends, a comfortable chair and hot chocolate (or some shots of brandy) and we are ready to go!
Will post more stellar impressions as soon a weather permits. Now, some pictures of the Fujis
