đŸ“· First Light: Saturn and Mars with the Canon PowerShot SX240 HS

Posted on September 7, 2018Mai 22, 2025 by admin

After days of waiting, the sky finally cleared. A few friends joined me for an evening under the stars, and after spending some time admiring late-summer favorites like M31 and M13, we turned our attention to the planets.

Saturn came first — and what a moment that was. If you’ve never seen it through a telescope, you’ll understand what I mean when I say we gazed at Saturn. That distant dot in the night sky suddenly became a world: a sphere, suspended in space, encircled by delicate rings and flanked by tiny moons. Without thinking much, I grabbed my smartphone and held it up to the eyepiece — and just like that, I had taken the very first astrophoto of my life.

Inspired by that moment, we decided to give the old Canon PowerShot SX240 HS a try. Using ocular projection, we clipped the camera in front of the 10mm eyepiece, now paired with a Barlow lens. We refocused on Saturn and fired off a handful of .jpeg images, followed by a short .mov video. The Canon’s video mode is fully automatic and offers little control, which made the footage dark and blurry. Focusing was tough, especially with such low light.

Still eager, we shifted to Mars. It was sitting low on the horizon — very low — and even through the eyepiece it appeared as a dancing reddish blur. We tried the same capture method, snapped a few shots, and decided that was enough for one night. It was time to see what we had.

Back inside, I opened up Autostakkert!2 and Registax for the first time. Processing those full-resolution .jpeg files was slow — each image was about 4MB, and I had no idea what half the buttons did. Drizzle? ROI? Alignment points? It was a world of its own. Eventually, I managed to stack a few frames, and then spent what felt like hours in Registax trying to sharpen them.

The results? Technically unimpressive — blurry images of Saturn and a soft red disc for Mars — but emotionally? Huge. You can clearly make out Saturn’s rings. Mars is a visible disk, not just a twinkling dot. These weren’t polished results, but they were my results. The very beginning of a journey that I now know has no end.

Clear skies,
Chris

SPACE NEWS

June 1:
Venus reaches its greatest western elongation, shining brilliantly in the pre-dawn sky. Ideal for morning planetary imaging—look east just before sunrise.

June 2:
The Great Hercules Cluster (M13) reaches its highest point in the sky. Excellent for telescopic astrophotography from dark-sky sites.

June 5:
Celebrate Galactic Tick Day—a quirky astronomical milestone marking our Solar System’s orbit around the Milky Way.

June 7:
The Arietid meteor shower peaks. While mostly active during daylight, early risers may catch a few bright meteors before dawn.

June 11:
The Strawberry Full Moon reaches its peak. It will be the lowest full moon in 18 years—look for its large golden glow near the horizon.

June 16:
Mars and Regulus appear close in the evening sky. Also, the Butterfly Cluster (M6) in Scorpius is at its best for deep-sky imaging.

June 19:
The Moon and Saturn meet in the early morning sky. A beautiful conjunction for wide-field or planetary setups.

June 21:
The June Solstice arrives at 02:42 UTC. The longest day in the Northern Hemisphere and shortest in the Southern—welcome the new season!

June 22:
The Lagoon Nebula (M8) in Sagittarius is ideally placed for observation. Use wide-field optics to capture its glowing clouds.

June 23:
The Moon passes near Uranus and the Pleiades before dawn. A great triple subject for wide-field astrophotography.

June 25:
New Moon. The sky is at its darkest—perfect conditions for Milky Way and deep-sky imaging.

June 27:
The June Boötid meteor shower peaks. Usually low in activity, but dark skies may reward patient observers with unexpected bursts.

June 29:
A conjunction of Saturn and Neptune offers a rare opportunity to frame two distant giants together.

June 30:
The Moon occults Mars in a dramatic celestial event visible from select regions—ideal for a lunar-planetary time-lapse.

All Month:
The Milky Way core is rising higher each night. Use the new moon week for wide-field shots from southern skies or dark rural locations.
