After many months of hibernation, today I finally imaged the Sun in H-alpha again, and I was rewarded with a fantastic view. Learn more in the article below. 👇👇👇 https://www.wondersofthesky.com/the-sun-today-2025-04-27/ #solarimaging #astrophotography #H-alpha #solarprominences

Just checked off a long-time bucket list project: imaging Markarian’s Chain-an iconic string of galaxies in the Virgo Cluster-right from my backyard! 🌌 I fully automated the session using NINA’s advanced sequencer: cooled the camera, calibrated guiding, set up a meridian flip, autofocus triggered by HDR changes, dithered every 5 frames, and got real-time progress updates via Groundstation and LightBucket plugins-all running on a mini PC I controlled from indoors. After 90 minutes of total integration, I captured this breathtaking view where you can count 23 galaxies! You can scroll to the next image to see the annotations. So thrilled to finally share this result! ✨ #astrophotography #markarianschain #virgocluster #backyardastronomy #nina #automation #galaxyseason

It's galaxy season, and I captured a portrait of M81 and M82 - Bode's elegant spiral and the Cigar's fiery core - in just 40 minutes from my backyard. Read the article to learn more 👇👇👇 https://www.wondersofthesky.com/galaxy-season-favorites-bodes-and-the-cigar-galaxy/

My 2024 Astronomical Retrospective. Despite significant obstacles like persistent bad weather and clouds, pervasive fire smoke, poor atmospheric transparency, and the demands of a busy life, I managed to capture some remarkable celestial moments. I made a YouTube video to collect some of the highlights. To learn more: https://youtu.be/0LXEoGU6PAc #astrophotography #andromeda #northernlights #comet #rosettenebula #veilnebula #solarimaging

November 9, 2024: I captured the Sun in its glory through a Hydrogen-Alpha Telescope! 🌞🔭 I enjoyed an incredible view of our star, with dozens of prominences, intricate filaments, and massive sunspots. Some prominences were bigger than our own planet Earth! Technical Details Gain: 0 Exposure: 1.929 ms Telescope: Lunt 40mm B600 Mount: Celestron AVX Camera: Player One Mars-M II Processing: Captured with FireCapture (best 30% of 1000 frames) Processed with AS!4, Autostitch and Astrosurface Final edits in GIMP #astronomy #solarphotography #hydrogenalpha #astrophotography

November 18, 2024: my first images of Jupiter for this planetary season. The atmospheric turbulence was very bad, but with some perseverance I was able to capture some fine details. #jupiter #planets #astrophotography

A few days ago, while re-organizing my old imaging sessions, I found some images of the Comet C/2020 F3 (NEOWISE) I took from a dark location (Port Elgin) on July 17, 2020. I re-processed those images with PixInsight and this is the final result. #cometneowise #astrophotography #comet

Another perfect night for astrophotography showed up, and skies were so clear it was impossible for me to resist the call of the cosmos. I decided to capture the Pleiades. Also known as Messier 45 or the Seven Sisters, it is a prominent open star cluster located in the constellation Taurus, with an approximate distance of 444 light-years and an apparent magnitude of 1.6, making it one of the brightest clusters visible to the naked eye. Equipment Setup Date: 2024-10-24 Lens: Rokinon 135mm Camera: ZWO ASI533MC-PRO Mount: Celestron AVX Filter: Optolong L-Pro (Light Pollution) Integration Time: 1 hour total (30x120 seconds exposures) #pleiades #starcluster #astrophotography #rokinon

As fall settles in, the constellation Cassiopeia rises high in the northern sky, bringing with it two of the most beautiful nebulae visible to astrophotographers in the Northern Hemisphere: the Heart and Soul Nebulae. On the crisp, clear night of October 21, I decided to revisit these cosmic wonders using my Rokinon 135mm lens paired with an OSC camera. The final image was nothing short of spectacular! #narrowband #astrophotography #heartandsoul #nebula

Yesterday night the sky was crystal clear. With the Moon rising early I decided to go narrowband and this is the California Nebula (SH2-220). I used a Rokinon 135mm lens, my ASI533MC PRO cooled at -10°, and a Celestron AVX mount. Total integration time: 1 hour (12x300 sec.) #astrophotography #californianebula #narrowband #optolonglextreme

Success! After a few failed attempts because of the clouds, on October 14 I was finally able to image Comet C/2023 A3 (Tsuchinshan–ATLAS) with my DSLR camera. I couldn't spot it with the naked eye, but it was very bright on the screen of my camera and with a long tail. Will stack and process the images later. #comet #comettsuchinshanatlas #tsuchinshanatlas #astrophotography
