David Charles Fanning, 40, of Vacaville shined a 50mw Green Laser Pointer at a Southwest Airlines passenger jet getting ready to land at Sacramento airport, according to the California Highway Patrol.He then shined the laser at a CHP plane that went looking for the source of the light, authorities said.

CHP pilot Jim Andrews, who estimates he's been lasered dozens of times in his career, says it's possible people assume that when they shine a device at an aircraft, that's the beam is just the size of a little dot -- when in fact it' s swath of blinding light that's now six to eight feet wide.

An amateur astronomy club based near San Antonio, Texas even coordinated signaling the International Space Station with a pair of powerful searchlights and a 1mw Laser Pointer in 2012, just to prove that it was possible.

As I have often stressed, an uncollimated telescope is no telescope at all — although it may serve as a flux collector, if fuzzy viewing is what you are into. A good telescope will have optics that have transmitting or reflecting surfaces that have been perfectly formed to within fractions of a wavelength, Their respective alignments must reach an accuracy commensurate with these proportions. HTPOW 300mw laser pointer collimators allow this to be accomplished. The Howie Glatter makes available improved alignment of a reflector's primary mirror.

HTPOW is a charming contraction of 'HTPOW collimation plug' and it does something remarkable to the already acutely useful 5mW laser pointer light being emitted from the collimator. After the laser beam passes through its anti-reflection negative lens, this neat little devil (placed at the base of the focuser tube), casts a returned shadow of the collimation target on its angled face, making adjustments of the primary mirror clearer and therefore more accurate.


Laser Sights for Handguns

There can be no sweeter sense of achievement than when you can see that an optical system is 'closed', with all elements in-line and on-axis — an achievement that is readily apparent in use, too. After all, once your responsibility of arranging the mechanics has been met, you can leave physics to do the rest.

Laser safety is a key pointing whenever users are use it in work, entertainment, projection or presentation. It is no kidding and never point it at human or animal body, eyes, moving vehicles, or aircraft. Do be cautious with your laser pointergadget in hands and enjoy the fun in life.
