Welcome back to Saimons Astronomy! I am thrilled to announce the official release of Moon Phase Widget 3, an application designed for those who recognize that the Moon is more than just a rock in the sky, but a beautiful phenomenon affecting our daily lives.

We are excited to announce that the latest versions of Collimation Circles (4.1.x and 5.x) now feature dedicated support for ZWO ASI cameras! This significant update enhances our Electronically Assisted Collimation (EAC) tool, helping astronomers achieve "near perfect" telescope alignment with ease. Many thanks to Mathieu Carbou to make all this possible!

Achieving sharp, high-contrast images with a Newtonian telescope often comes down to one critical task: collimation. In his latest video, Dave Aldrich explores a game-changing DIY approach to this process, moving beyond standard laser collimators to a camera-based system he calls the "DECAL." While the hardware build—a clever $30 assembly using an Arduino USB webcam and 3D-printed parts—is impressive, the real star of the show is the software that makes it all work.

Collimation Circles application enters a beta stage. All features are finished. There will be no major changes in this version. It's ready for daily usage, but some minor bugs may still be present.

Michael DUBOIS (https://www.michaeldubois.be/astronomie) has done some great work by collimating his dobsonian telescope, 305 mm Explore Scientific with focal length of 1525 mm, with Collimation Circles applicaton.
