I set up my camera on a tripod and programmed it to take 10 second exposures all night long from my light polluted yard. This focuses on the northern portion of the Milky Way, capturing satellite after satellite, a few planes, faint nebulae and dust, and a huge distant galaxy.

On one of our few clear and smokeless nights, I set up a camera to try to capture the Perseids. I ended up taking over 1200 shots that I will be using for a couple projects. Browsing through the images to see how many meteors made it in front of the camera, I came across this neat one leaving a wispy dust trail after it vaporized.

Galaxy Season! The Little Pinwheel Galaxy is a face on spiral galaxy in the Ursa Major constellation approximately 40 million light years away.

The Croc's Eye Galaxy is in the Canes Venatici constellation and has two ring structures that astronomers do not understand how or why they formed.

The Leo Triplet is a group of spiral galaxies approximately 35 million light years away. They are gravitationally locked and are slowly reshaping each other.

A surfboard in space! The Surfboard Galaxy is a spiral galaxy seen partly edge on. It is 46 million light years away, which means we can only see what this galaxy looked like 46 million years ago because that is how long the starlight took to reach earth and land on my camera sensor or our eyeballs through a telescope. It is right "beside" a dying star known as the Owl Nebula, which resides in our own galaxy.

For stargazers, spring is known as galaxy season. Through the summer and winter months, our night sky is dominated by different parts of our own galaxy, the Milky Way, but in the spring, our night sky is dominated by distant galaxies as we are peering out into the universe in the constellations Leo, Virgo, Coma Bernices, and all around Ursa Major.

The Big Dipper, part of Ursa Major, is in the sky in the northern hemisphere all year round, but imaging this region is most favourable in the spring when it is high overhead. I'll be giving a galaxy tour each day for about a week or so of the hidden gems in this part of the sky. Today's is the Pinwheel Galaxy, a stunning spiral galaxy just above the handle of the Big Dipper.

Happy to see the astronauts home safe!!

Wow, this is incredible! Astronauts on Artemis 2 took this shot of the night side of earth lit up by the full moon. The auroa borealis and aurora australis can be seen and, I'm not sure, but the bright star up to the left could be Venus.
