Telescope Reviews: 4 Pinholes For A Revolutionary Artificial StarS!!!

The star test is the ultimate method for the collimation and quality verification of your telescopes. Sadly, a real star is not always available, and you really may not want to spend your precious observation time doing collimation and verification even when it is available. Of course, you will also need a good tracking system for doing star test with the moving star. After all the troubles, due to the turbulence, the real star may not even reveal the true quality of your telescopes.

An artificial star will provide you an excellent alternative mean to do the star test anytime and anywhere you want, without all the drawbacks of the real stars. However, the problem with artificial star is that you really need different size of artificial stars for different telescopes of different apertures with different F/#, and even for the same telescopes but at different distances, and under different lighting environment.

Our 4-pinhole module (P5123A) is a perfect solution to this problem. It is a piece of extremely thin stainless steel sheet square of 50mm * 50mm, with 4 precision pinholes (50/100/200/300 microns). It will enable you to test practically all the telescopes of different apertures with different F/#, from any reasonable distances needed! It will enable you to build a revolutionary Artificial Multi Star, so you can instantly find out which star is best for your particular telescope at that particular distance under that particular lighting environment.
