New data on interstellar object 3I/ATLAS reveals 'improbable' 120-degree symmetry and organised jets, defying standard ...

The 400,000-kilometre anti-tail of 3I/ATLAS is one of the most remarkable aspects that have ever been seen on an interstellar object. The particles in it are too large to be typical cometary dust, and ...

I/ATLAS’s enigma continues as its closest approach to Earth is nigh ...

In my opinion, the Bahtinov mask is one of the most useful inventions for astrophotography. The traditional use of a Bahtinov mask is for focusing a telescope only and is not used for collimation of ...

Dr. Jeffrey Smith began his academic passion in the field of Accelerator Physics. After building a cyclotron, a small particle accelerator, as an undergraduate at Knox College, Jeff matriculated at ...

Introduction: Myocardial perfusion imaging (MPI) with a multifocal collimator, such as the SMARTZOOM, has been using the same iterative reconstruction with additive update, driven a pre-conditioned ...

Learn how to optimize a budget Newtonian telescope for astrophotography with collimation tips and more. AOC Is Running Out of Time Bryce Harper leaves Phillies-Braves game after Spencer Strider ...

Background The eye lens is particularly vulnerable to radiation during endovascular treatments for intracranial aneurysms due to prolonged exposure under high magnification. This study presents a lens ...

We're excited to announce the addition of Shear-Plate Collimation Testers to our growing catalogue of precision optical components. These new testers are designed to ensure accurate laser collimation ...
