🦉 Messier 97 (M97), the Owl Nebula, is a planetary nebula in the constellation Ursa Major, approximately ~2,030 light-years from our planet. It spans about 3.4' in apparent size, which corresponds to a physical diameter of ~2.4 light-years, making it one of the larger planetary nebulae observable from Earth. 🛰️ The fastest spacecraft ever built is NASA’s Parker Solar Probe, designed to study the Sun’s outer corona. It reaches speeds of up to 690,000 km/h as it swings close to the Sun—faster than any previous human-made object. Despite this incredible velocity, covering a distance of those 2.4 light-years would still take around 3,760 years! 🏛️ If NASA's Parker Solar Probe had been launched back then—around 1735 BCE— at a time the Minoans 🐂 had palaces like Knossos with running water and frescoed walls, it would still be flying (!) through interstellar space today, just now nearing a star 2.4 light-years away. ✨ M97´s central star (see photo) is a hot white dwarf with a surface temperature exceeding 120,000 K, illuminating the ejected outer layers of ionized gas that form the nebula. M97 has an apparent magnitude of 9.9, and its low surface brightness (~13 mag/arcmin²) can make it challenging for small instruments; observers should use an 8-inch telescope to resolve structural features. The nebula emits strongly in the [O III] (495.9 and 500.7 nm) and Hα (656.3 nm) lines, making it ideal for narrowband imaging or visual observation using an OIII filter, which greatly enhances contrast against the background sky. My attached photo of M97 was captured using a Vaonis #Vespera II robotic EAA telescope, without any filters, and later post-processed manually by me, demonstrating that even under modest conditions, careful technique and processing can reveal the soft, haunting glow of this ancient stellar remnant. M97 is estimated to be around 8,000 years old, representing the late evolutionary stage of a low- to intermediate-mass star (~1–2 M☉), and is expanding at a rate of roughly 27 km/s. Best viewed from the Northern Hemisphere tonight around midnight, M97 offers a technically rich and visually rewarding target for us #stargazing and #astrophotography enthusiasts alike. 👋 Hey friends!

Photo challenge: show me a cityscape! 🌆

Hello Everyone, here is my latest capture - a wide field view of the galaxy M77 (far left), NGC 1055 galaxy (upper middle), and the bright blue star on the right - Delta Ceti. I used my Celestron RASA telescope and ZWO ASI533MC color camera.

The Medusa Nebula 📸 Here is my latest picture of Abell 21, a large planetary nebula in the constellation Gemini. This is a tough target that requires much more overall exposure time than I collected, but I just couldn't help myself 😊 This version is in the HOO palette, using only 2 filters (H-Alpha and OIII) to create. This is one of many test images captured with one of the most affordable monochrome astronomy cameras on the market (585MM Pro) It's an excellent choice for anyone looking to dive into mono imaging!

I think I just captured one of my best moonshot ever 😍 Extreme moonshot captured at 900mm with Sony A7IV+ Sony 200-600mm. Just look at the compression 🔥
