Lunar Eclipse Jan 2019

Deep-sky astrophotography is the ultimate hobby for nerds; it combines endless tinkering with highly specialized technology, exploration of the cosmos, and constant challenges, achievements, and learning. But, could this hobby be automated to the point where anyone can do it? Products such as Stellina and Unistellar promise to deliver an experience where you can plop…

Located 63 million light-years away in the constellation Coma Berenices, M91 is part of the Virgo cluster of galaxies – and if you zoom in and explore this image, you’ll find many other galaxies surrounding it, and also far in the distance beyond it.

Like the Bubble Nebula, and Thor’s Helmet, this is formed by the fast stellar wind of the extremely hot star at its heart – which interacts in complex ways from the wind left over from when this star was a red giant. This is roughly 5,000 light-years away. These images were taken over the span…

Formally SH2-155, the Cave Nebula lies about 2,400 light-years away within the constellation Cepheus. It’s part of a much larger region of gas and dust (called a molecular cloud). This region is mostly ionized Hydrogen, but there’s just enough Oxygen – blue in this image – to make for a pretty picture. Capturing that Oxygen…

This morning, my cat woke me up at 3 AM, and I noticed it was clear outside. But, the sun would start rising in just a couple of hours, so doing some super-long-exposure shot of a faint nebula wasn’t in the cards. However, globular clusters don’t take long to image, as they are relatively bright…

This dim nebula in the constellation Perseus has no name, apart from its catalog numbers NGC 1491 and LBN 704. I think it deserves one. It reminds me of the Bubble nebula – if you look closely, you’ll see a “bubble” at center being created from the stellar wind of the hot star that is…
