By shifting the phase of light wavelengths, spikes generated from the secondary mirror fixed spokes of Newton and Cassegrain reflection gateways, which were previously thought to be impossible to eliminate, can be prevented.

This binary appotizer technique, which superimposes the maximum and minimum values, has been further improved to the point where some have wondered why telescope makers have not adopted it. It eliminates the spikes in the spider and makes stars appear round, just like a refracting telescope.

Stray light is also reduced, and this makes it possible to see parts of the sky that were previously invisible and stars such as double stars that are close together. The dispersion caused by the diffraction rings is improved by 30-50%, resulting in more improved contrast and resolution compared to the unattached version. Spider diffraction disappears especially in photography.

In the photograph of the Bubble Nebula provided by AM in Gunma, the inside of the bubble can be seen more delicately, all the star images have no spikes, and the faint stars are well represented thanks to the reduced glare.

Thank you very much for your previous product for BKP150. I made a few adjustments to the installation. I recently observed Jupiter and Saturn. After installing this product, I was able to see even the Great Red Spot and was impressed by the improved contrast. I am very satisfied with the results. I am very satisfied with this product. Thank you very much.

When I took a picture of it, the diffraction of the spider was no longer visible. Thank you again for the opportunity.

Last night, it was a beautiful sunny day, so I did a live-action test in my yard. I photographed Antares and it disappeared almost perfectly. However, I took one frame at a time under the same conditions for comparison photos. The spikes are likely to remain, but it works well enough.

When I checked the other day in actual shooting, the spider light stripe disappeared, and I realized again that it is effective. I am a successful bidder for the BKP300,F5 reflector, which has been dropped by the

Sorry for the delay in reporting. I have just recently confirmed the effect. It is true that the diffracted image caused by the secondary mirror support spoke disappears. I was always concerned about the direction of the diffracted image when I used to use the "A" system, but it seems that I don't have to worry about it anymore (I haven't seen it yet because of the season). I will take the opportunity to look at the "4" stars, but I was able to see Hercules' ζ star, Antares' companion, and Soli's ν quadruple without any problems. I feel a bit sad without the 。。。。
