Welcome to Stellar Products


 

Astronomy is one of my Hobbies

 

My 2017 measurement of the solar-induced gravitational deflections of some stars seen during a total eclipse was certainly a highlight, but I’ve been busy with other telescope projects since then. Einstein originally suggested to astronomers that they look for this small deflection during the day, but it was impossible to image stars with the required precision. With modern technology, I did my best to do this, but still failed. Einstein also suggested that astronomers look for stellar deflections near Jupiter, where the deflections would be 100x smaller, but nighttime measurements could last hours, not just a few minutes. I am in the middle of trying this!

 

During lulls in imaging for these deflections, I’ve contributed to some occultation events and have done some imaging of Mars. I also captured the Great Christmas Conjunction of Jupiter and Saturn in December 2020. Planning ahead, I am assisting in preparing for the 2024 total solar eclipse.

Stellar Products was the first company to manufacture standard adaptive optics systems to both amateur and professional astronomers. The AO-2 adaptive optics system provided image stabilization for planetary photography. The AO-5 adaptive optics system will provide correction of defocus and astigmatism as well as image stabilization. Either of these systems allows the astronomer to improve his images to the limit of his telescope.
