The star next door.

A progression of photos taken at 15-minute intervals from 10:30 PM to 12:15 AM on the evening of Jan 20-21, 2019. Click to zoom in – there’s a lot of detail!

That massive sunspot group rivals the size of the one that triggered the Carrington Event in 1859. So far it has kicked off some large coronal mass ejections heading our way, but fortunately nothing on that scale. Let’s hope we just get some pretty auroras from this, and nothing more damaging!

Imaged in narrowband filters from my suburban driveway. This object lives up to its name with the right color mappings!

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…

Located about 1,300 light-years away, the Iris Nebula is a reflection nebula – unlike most of the nebulas on this site, it’s not made of ionized gases emitting light of their own. It’s just starlight reflecting off clouds of dust. Reflection nebula are harder to image in light-polluted skies, since the narrowband filters we use…

A lot of things have to come together for a good image of the planets. The air needs to be as still as possible, the planet you’re imaging needs to be as directly overhead as possible, and the planet itself should be as close to the Earth as possible. And then, all your equipment has…
