DESCRIPTION
Like the Newtonian telescope, the Newtonian projection device uses two first-surface mirrors: a curved mirror and a flat mirror. In the Newtonian™2 projection system, the curved mirror is convex and displays the image from a projector over a dome. (The primary mirror of a Newtonian telescope in concave and designed to gather light and focus it onto an eyepiece).
In both the Newtonian™2 projector system and the Newtonian telescope, the flat mirror transfers the image to the mirror in the projector and to the eyepiece in the telescope. The Newtonian™2 projection system uses the Go-Vex™ first-surface convex mirror. It’s most critical design criterion is protection of the primary mirror during transport and while in projection mode.
ADVANTAGES
1. The Newtonian™2 is less expensive that fisheye solutions. There is no debating this fact.
2. The Newtonian™2 eliminates chromatic aberration associated with the horizon of fisheye lenses.
3. Newtonian™2 projection solutions are resolution independent with the only limited to the resolution being the projector you have chosen to use.
4. Newtonian™2 projection solutions are infinitely upgradable. You are not stuck with the initial projector you have chosen. As projector technology continues to improve in lumens and resolutions, you are free to change out for a new projector while repurposing the original projector for classroom or other uses without penalty. This makes Newtonian™2 mirror solutions green and better for the environment.
5. More pixels on the dome! A fisheye lens coupled with a high definition projector looses over 50% of the available pixels due to the round nature of the dome master that the fisheye lens must project. A warped image, designed for a mirror captures 84% of the available pixels giving you more pixels on the dome and higher resolution regardless of what ever apples to apples projector comparison you choose to make. One of the product images illustrates this,showing 3 images.
MISSINFORMATION
1. The Newtonian™ 2’s Go-Vex Mirrors are criticized for being so delicate that you can not even blow on then. Not true. We maintain a caucus approach to the care and maintenance of the Go-Vex™ Mirror, but it is the only cleanable first surface mirror available to the market today.
2. The Newtonian™2 coverage is distorted and not complete at the back of the theater. We want to point out that with the Newtonian™2 system, when properly aligned in portable domes, cover over 95% of the dome without distortion. And in fixed domes using, Newtonian™2 systems ALL distortion and coverage issues can be eliminated by careful alignment. As evidence, note the product photo provided by Paul Bourke. Using a Newtonian™2 projection system, with a Go-Vex Mirror. Paul is covering 100% of the dome without distortion and is projecting at the cove line allowing for the star ball projector to be used without causing a shadow.
