Bode’s Galaxies (M81 & M82)

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!

I’ve imaged the Rosette Nebula several times, but this is the first from the dark skies of Central Texas and with some better optics as well. I took a lighter touch on the processing this time, since the data was better – and it results in a smoother, more natural look than previous takes.

Combining 25 hours of data shot over two years, here’s M64. It’s an odd one, with counter-rotating disks that seem to have funneled all that dust in the center there. They think it’s the result of a merger of two galaxies that were spinning in opposite directions. Located about 17 million light-years away, in the…

The Rosette Nebula is about 5,000 light-years away in the constellation Monoceros. It’s the birthplace of the cluster of stars it contains. While it doesn’t look much like a Rose in this view, the false-color narrowband image below brings out more of its structure. 7 1/2 hours of total exposure time, on New Year’s Eve…

Here’s another galaxy with no nearby neighbors, and no catchy nicknames either: NGC 3344. It’s about 22.5 million light-years away within the constellation Leo Minor. Although it doesn’t get the love it deserves, it’s a glorious face-on barred spiral galaxy that’s about half the size of our own Milky Way. Explore the space around it,…

M104 is known as the “Sombrero Galaxy” due to its visual appearance – but a deep, long-exposure image reveals its true structure. It’s a lenticular galaxy about 30 million light-years away, about 30% the size of our own Milky Way galaxy.
