Designed for domes with a diameter of 10~25m, compatible with the MEGASTAR-FUSION

The optical planetarium projector MEGASTAR – IIA was developed using the latest technology and fits for domes from 10 up to 25 meters in diameter. In order to project a plenty of stars as separate fine particles, even those which can not be distinguished with the naked eye, we use a star plates with holes of 700 nanometers minimum size. A system of such star plates makes possible to reproduce the real Milky Way with the depth specific to MEGASTAR optical projectors.

The projector system has as many as 32 lenses. Also, the brightest 40 stars (can be optionally increased up to 62) are projected independently each with its own color and magnitude.

MEGASTAR-IIA is the first planetarium in the world to implement LED lamp as light source for middle-to-large domes. Due to maintenance-free oriented design there is no need of lamp replacement.


Number of projected stars

From 1 million up to 20 million stars. You can choose for yourself a sky with 1 million stars with easily distinguished constellations, or go up to 20 million stars for a magnficent starry sky that you can also search for star clusters using binoculars.

Bright star projectors

Each bright star is reproduced with its color and magnitude. Bright stars can be controlled independently allowing smooth fade, twinkle , on/off, and variable stars simulation.

Solid state shutter

It is an electronically controlled shutter without mechanical parts, which makes possible to mask an arbitrary range of the starry sky or to display only an arbitrary range. The solid state shutter can be used for both horizontal and tilted domes, and remarkably improves compatibility with a digital video.

Equatorial camera & laser

The camera and laser device are mounted in the central belt part of the main body. It makes possible easy calibration of the star projector and precise position alignment with a digital planetarium.

Manual console

The optional Manual console enhances operability. Motion, brightness and custom controls become available within touch with analog feeling.
