Revisiting the Crescent Nebula
I’ve imaged this one before, but for whatever reason I picked up way more detail on it last night. Part of it’s a better camera and better tracking on the telescope mount, but I think conditions may have just been really awesome last night. It’s not normal to have this many good nights for astrophotography…

Revisiting the Northern Pinwheel Galaxy (M101)
Somehow I’ve neglected to go back to one of the showcase galaxies of the spring sky with newer equipment and software: M101, the “Pinwheel Galaxy.” Located about 21 million light-years away within Ursa Major, this relatively close galaxy shows lots of active star-forming regions revealed by red HII gas. Those red spots are nebulae in…

The Butterfly Galaxies
The galaxies NGC4567 and NGC4568 are colliding 60 million light-years away. This is really pushing the resolution limits here; we had good “seeing” last night meaning not a lot of turbulence to smear out the light reaching my telescope, and I carefully collimated and calibrated things prior to imaging last night. About as good as…

Back to the Bubble Nebula
The Bubble Nebula still has a soft spot in my heart… it’s what really got me going with astro-imaging years ago. It’s just such a fascinating, gorgeous object and it really inspired me the first time I saw it. Here’s my deepest exposure of it yet: over 20 hours of exposure time, in the “Hubble…

M64, The “Black Eye Galaxy”
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 galaxy M91
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.
