  • Amazon satellites are blinding our telescopes!
    Jun 19 2026

    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 streaks in astronomical images.

    For amateur astronomers, these satellites are described as an "inconvenience fixed by math". By using shorter sub-exposures and pixel rejection algorithms like sigma-clipping, hobbyists can mathematically remove satellite trails from their final stacked images.

    In contrast, professional astronomy faces a structural threat. Sensitive facilities like the Vera C. Rubin Observatory suffer from sensor saturation and "ghosting" that ruins data. Also, space is no longer a sanctuary; simulations suggest that once these constellations are fully deployed, nearly 40% of Hubble Space Telescope exposures will be contaminated, while next-generation wide-field missions could see contamination rates exceeding 96%.

  • Understanding Telescope Focal Length & F-Ratio
    Jun 18 2026

    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 here: https://astroforumspace.com/telescope-focal-length-f-ratio-explained-for-astrophotography-and-stargazing/

  • Aperture: Is a Bigger Telescope Always Better?
    Jun 18 2026

    n this tutorial, we explain why telescope aperture matters, but also why just buying the biggest aperture telescope tube out there might not be the best thing for you. The tutorial explains what aperture is, how it relates to light-gathering power and resolution, and we briefly discuss the various telescope types that could deliver such a large-aperture view of the night sky, along with their pros and cons.

    Enjoy and keep looking up!
