Does the Cat's Eye (NGC 6543) look like a broken sprinkler? 💦
23 hours of exposure reveals magnetic fields twisting the gas jets in wild ways.

NGC 6543 - Cat's Eye Nebula
I first tried imaging this nebula back in August 2023, with the RASA 11. With such a wide field setup, and 4 hours of exposure, the Cat's Eye was tiny. I could barely make out any detail. But it was a...

This image of the Dumbbell Nebula gives us a glimpse of what our Sun may become when it runs out of fuel in the distant future. We're seeing the death throes of an aging star, expelling its outer layers into an expanding shell of debris - its final farewell to the galaxy.

We're looking at the tail-end of the witch's broom - part of the Veil Nebula within the larger Cygnus Loop. The shock wave from a supernova explosion provides more than enough energy to ionize the oxygen in the debris, resulting in the lovely blue strands visible here.

This is C7, a spiral galaxy 12 million light years from here. It's a little smaller than our own galaxy, with a diameter of 80,000 light years. Seen from Earth, C7 is tilted at a rather pleasant angle toward us, which I think accentuates its lovely spiral arms.

My first attempt at f/11 photography with the EdgeHD 14" telescope. Imaging at such a long focal length presented some new challenges, but I think the result is promising. This is a close-up of the Cygnus Wall - an area of star formation within the North American Nebula.

Red dwarf K2-18 may harbor extraterrestrial life. It's the home star of the first habitable-zone planet found to have water along with an atmosphere that shows signs of life. I thought it would be fun to take a picture of it. You'll need to zoom in to see it.

The iconic Horsehead, clearly silhouetted against a beautiful scarlet curtain of ionized hydrogen alpha.
At just 1500 light years, it's quite amenable to being photographed. Requiring minimal processing, it looks like a work of art right out of the gate.

Explosions of the kind that gave birth to this Jellyfish are the means by which atoms are manufactured and distributed into the cosmos - a process essential for the development of planetary systems and the evolution of life. Without these nebulae, we wouldn't exist.

The Fossil Footprint contains a number of massive stars whose UV radiation ionizes the hydrogen clouds making them glow brightly. I especially love the bright yellow walls at the top, formed when gases are compressed by shock waves - real gates of heaven stuff!

At the suggestion of astronomer Paul Bailey, I added a small batch of 30-sec exposures. This made the core less blown-out, while preserving detail in the darker regions. Whoever said you can't teach an old dog new tricks?

At 1,344 light years away, the Orion Nebula is the closest big star factory to Earth, making it one of the brightest deep space objects in the sky. It can even be seen with the naked eye, as a hazy patch of light surrounding the middle star in Orion's sword.

I refrained from making the stars blink on and off.

The dark nebula running up the middle forms the butterfly's body, with the bright wings stretching out to the sides in a sort of teal color. Some lovely star clusters are distributed around the nebula like colorful glistening pearls, and more than a match for any holiday decorations!
