(External Adjustments)
SN-9. Variable and fixed powers with external W&E adjustments. Lots of elevation travel, great resolution, rugged, and dependable.
Long eye relief eyepiece option can be added to most of the product line. Adds about an inch. Great for larger caliber's like .50 BMG.
90 click knob option can be added to most of the product line. For .308,
100-1000+ yards in one revolution.1/2MOA per click.
BDC and custom knobs available.
Second run of M40 scopes due to success and demand of the first run.

Problem:
MOST current, state of the art telescopic sights, are basically unchanged from the 1920's. They use and internal adjusting erector tube with very small lenses to magnify, erect and modify the image from the objective lens. These designs have many serious faults. They are: |
|
1. In a 1" dia.
Tube the erector tube has to be about .500" dia to have any serious
long-range capability and the 30mm tube about .600". This means
they have erector lenses of about .385" to .500" max.. This
means there is poor performance in the erectors or simply that when
higher magnification is pumped through the system it can't handle it.
This is defraction limitation or "empty magnification" and
the higher the magnification the poorer the "seeing power".
|
|
2. Because
of the condition mentioned above, there is not enough room in the smaller
tubes, using large erector lenses to get large amounts of elevation
tavel for long ranges; and when that is accomplished, there is tremendous
"vignetting", or optical interference.
|
|
3. When poor performing
erector tube and lenses above fail worst, is when vignetting occurs.
This occurrence is a result of the erector tube adjusted to a radical
angle where the angle of incidence of incoming radiation is so great
that is poorly utilized. That means you can't see well in that circumstance.
|
|
4. Another poor aspect
of current competitive design that our competition is using, is that
the scope must be made to accomodate current state of the art designs
made for tubular scopes. These designs and the small diameter tubes
mandate poor preformance, particularly in the shorter "compact
scopes" and the very high power "percision scopes".
|
|
5. Inaccurateness "built
into" the design itself, comprimised by the geometry and methodology.
Conceptual purpose are not proven by consistent and empirical results.
|
Solution:
leave the current state of the art scopes behind and build a scope without
these flaws.
Summary:
A "0" ACCURACY MOVING ERECTOR TYPE LENSMATIC SCOPE IS AN OXY-MORON.
SN-9 Asaerts EA (Externally Adjustable Windage & Elecation)
In this optical system the entire telescopic sight moves to accommodate windage
and elevation changes, rather than just moving the internal erector tube,
as in most hunting and general service type of telescopic sights. Some very
impressive performance features of this system, as applied to long ranges
shooting are: Total Movement In M.O.A.- means longer-range elevation capabilities.
External W&E adjustments are not limited by the erector tube
diameter fitting the I.D. of the tube itself. This unit has more M.O.A. capability
than any long range scope made in the world today!!!
More Light Transfer
means that because of larger (lenses or prisms) capacity on the inside of
the scope with a lack of an erector more light gets through.
Better Light Transfer
means that there is less Vignetting or simply that the erector that is normallly
at an angle is now straight and lets better light through.
More Accurate Adjustments
means that when an erector moves on an angle in any direction from the optical
axis, the erector tube-W&E shaft foot, being flat and square, changes
angle of incline, and also it's performance value per click. The ASA-ERTS
"no erector tube - full lens diameter" cancept has no such change.
Stronger-More Reliable
means what without the erector tube, not only can we use larger, better seated
lenses, but we make the tube larger, stronger and with
more inside clearance.

Knob Values
E&W knob click values are variable. By sliding the rear turret farther
rearward, a finer click value is achieved. Preliminary tests indicate values
of
aproximately 1/20 MOA to 1/2 MOA are achieved depending on thread pitch and
clicker values. A table of power and subtentions will be included.
