Technically this nebula is called IC63, but its common name “The Ghost of Cassiopeia” seems much more timely, given Halloween is just around the corner!
Imaged all night last night, mostly in true colors with some Hydrogen emissions added in to enhance it.
NGC253 is most commonly known as the “Sculptor Galaxy,” because it’s found within the constellation Sculptor. You probably haven’t heard of Sculptor – that’s because it is considered a Southern-hemisphere constellation, and it’s only visible in the US from Southern states such as Florida. It’s also known as the “Silver Coin Galaxy.” It’s part of…
This galaxy is only known as M74. At 32 million light-years away, it’s about as far as you can get for a halfway decent image taken from Earth. It is a “grand design” face-on spiral galaxy. Look closely and you’ll see a few more galaxies in the background that are much more distant, and therefore…
The iconic Horsehead Nebula, near Orion’s belt. Shot in narrowband over two evenings.
This week’s target was Thor’s Helmet (NGC 2359), an emission nebula in Canis Major a rather distant 12,000 light-years away. It’s formed by a Wolf-Rayet star in its center, which is a crazy-hot star whose immense stellar wind is bunching up and ionizing the gases around it in these complex patterns. It’ll probably go supernova…
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!
The Heart Nebula is a little too big to fit within the field of view of my telescope, but its inner “heart” is interesting in its own right. This is star cluster Melotte 15, formed from the gases within the Heart Nebula – and some of that gas remains, forming interesting clouds and formations where…
