What is boresight angle?
The angle from boresight refers to the angle of the SM in relation to the centre-line of the AP antenna.
What is the purpose of boresighting?
Boresighting is a method of visually pre-aligning a firearm barrel’s bore axis with the target, in order to more easily zero the gunsight (optical or iron sights). The process is usually performed on a rifle, and can be accomplished either with the naked eye, or with a specialized device called a boresighter.
How does a laser bore sight work?
The laser bore sight fits into the chamber of the firearm. Once the laser is turned on, the firearm is aimed at the target and the scope or sights are aligned to aim at the laser dot on the target. In an ideal world without wind, air resistance or gravity, the firearm would be dead on without further need for sighting.
How accurate are bore sights?
First, they are a far more precise method than using your eye. While visually bore sighting a firearm may get you on paper at 100 yards, laser bore sighting will put you much closer to center and will require less ammo in the long run when zeroing the rifle.
How accurate is a bore sight?
How far should you laser bore sight?
about 25 yards
Laser Boresighter These devices emit a laser, which should be pointed at a target about 25 yards down range (always in a safe direction).

What is the best distance to zero a red dot sight?
For handgun users with red dot sights the 15 yard and 25 yard zeroes are most popular because the chances of people engaging targets at distances much further than this doesn’t happen very often, if ever.
What causes telescope eyepieces to fail?
Typical causes include the poor positioning of baffles within a refractor, a secondary mirror that is too small to fully intercept the light cone from the primary mirror in a Newtonian reflector or the use of narrow adaptor tubes to attach the eyepiece or camera to the telescope.
Can I Fix my Telescope’s aberrations?
Unfortunately, not all aberrations can be eradicated: some are caused by manufacturing or assembly errors, others are simply a limitation in the telescope’s design. Of the six we have looked at, chromatic aberration and astigmatism are unlikely to be fixable at home. However, the other four can be tackled successfully.
Why are spherical mirrors not used in telescopes?
Spherical mirrors suffer from spherical aberration in which light falling toward the edges of the mirror is focused at a different point to light falling closer to the centre. This means that with the exception of very long focal length telescopes, they are unable to focus the whole field of view at the same plane.
Why do I need a baffle tube for my Telescope?
Catadioptric scopes like Schmidt-Cassegrains, Maksutov-Cassegrains or Ritchey-Chrétiens require a baffle tube to prevent light from the front of the telescope falling directly onto the focal plane before reflection from the primary mirror and this can cause vignetting.
