Science EN ↓ 6 episodes

Hi there! I'm Wido Oerlemans and I'm an amateur astronomer and astrophotographer from Utrecht, The Netherlands :-). In 2016, I took my first steps into this hobby and I've been hooked ever since. I'm producing FREE content about astrophotography and space. Any SUPPORT is greatly appreciated! On this AI podcast, you can listen to the contents of my astroblogs where I share: - Essential knowledge about Telescopes, mounts, and astrocameras - Tutorials about how to photograph The Planets, Moon and the Sun - Tutorials about how to photograph deep-sky objects (nebulae, galaxies, star clusters...) -...

Strain Wave Mount vs Classic GEM: My 8-Year Verdict | From AVX & EQ6-R to AM5N 02.07.2026 26:14

Are you trying to decide between a modern Strain Wave (Harmonic Drive) mount and a classic German Equatorial Mount (GEM)? In this video, I take you on an 8-year trip down memory lane—from my beginnings in 2018 with the Celestron AVX, to upgrading to the heavy-duty Sky-Watcher EQ6-R Pro in 2020, and finally transitioning to the ZWO AM5 and AM5N strain wave mounts. We break down the real-world pros...

Amazon satellites are blinding our telescopes! 19.06.2026 19:01

IN this podcast we discuss the recent launch of 36 Amazon Project Kuiper satellites aboard an Ariane 6 rocket, marking a major expansion of low Earth orbit (LEO) mega-constellations. This growth introduces a significant "twilight penalty" ; because Amazon’s satellites orbit at 630 km—higher than Starlink—they remain illuminated by the sun much longer after sunset, creating persistent bright streak...

Understanding Telescope Focal Length & F-Ratio 18.06.2026 24:02

In this podcast episode, we take a deep dive into telescope physics. We break down how focal length and f-ratio influence your stargazing, from determining magnification for visual observers to optimizing image scale for astrophotographers. Learn the practical trade-offs between different telescope designs and access interactive calculators for field of view and light speed in the original article...
