image quality will blow you away.
These are made from average units (Mechanically they function well). With
the eyepieces replaced. Normally binocular eyepieces are 3-4 element
with marginal correction for color and edge sharpness. But the correction on
Siebert 6 element eyepieces are exceptional. The eyepieces used for
refit are shown in the picture below when compared to a
Japanese made Meade 26mm Super plossl. The eyepieces used do not add to the color correction
problem (but in fact minimizing it.) False color is almost
completely absent under most viewing conditions.
A little doubt is
Many people think that the
Objectives and prisms have more to do with the quality of view then
the eyepieces. Is this true? NO!, not
at these magnifications. A quality 50mm objective could be pushed to
100 times without a failure. Most binoculars objectives can easily
be pushed to half of that. These binoculars do not have to go nearly
that high but as you see in the pictures at the bottom of the page
they could go to 40x. In this case prisms are not the bottleneck. It
is the failure of the eyepieces that brings down most binoculars
which in this case is easy to fix.
I have never felt comfortable with
a pair of binoculars under $400. But after refitting one of my own I
could immediately see a big difference in terms of comfort,
sharpness and eyerelief which is 22mm in this case. The
stars never looked like pin points in the field and the images in
both eyepieces never seemed to blend well at night. Their
was always a spike of flair I could not get rid of. The stars always
looked a little different for each eyepieces which was unacceptable.
eyepieces are not wide field at 50deg but are razor sharp to the
edge of the field and have be given a lot of attention as to collimation
so the stars blend into one without problems.
So you have 60 days to determine if the views these
provide are good enough to justify the cost. They also have separate
adjustable eye focus and a user collimation adjustment. The units
shown have their rubber eyecups removed so you can see the optics
better. Every unit is tested under the stars before they can be
shipped so there might be some shipping delays. This is important so
as to assure a perfect star test.
The criteria I use for
determining which units I use to convert is they must mechanically
function well. I have to be familiar with the quality of the
objective lenses and prisms that are being used. These may not be
for everybody, but if interested feel free to contact me. I will
even pay your return shipping* if you do not like them. Try getting
that from any other company. I am confident that after you use them
once you will not want to be without them.
Remember 60 Day return policy and free return
shipping if not satisfied, you simply can't go wrong.

pictures below are to give an idea of the color correction mainly even
though you also can see the fact that the binoculars do not bend the edges
of the FOV. Since the camera was hand held in front of the binocular
eyepieces, these pictures tell you little about the sharpness of the binos
which is better then any pair under $500 and as good as pair costing much

the edge. They have 19mm ER. and 55deg FOV.
The 8x model has a field of 340 ft@ 1000 yds.
The 10x is 290 ft . They deal with impacts better then most because they do
not use binocular cement to hold the prisms in place. The are light weight
They have most of the same
basic design benefits mentioned above but are much less expensive. They are great for
every day use as well as for
Astronomy. They have become my favorite grab
