M38 and NGC 1907 (Nov. 27, 2013)


Here is M38 and the nearby NGC 1907.  Both are about 5,900 light years away in the constellation Auriga.  The two clusters have similar ages, but a study of their motions through the sky suggests that they are merely flying by each other.

I shot this while waiting for the Alnitak to make it over the trees; the M38 data came out well enough.  This image is shrunk about 25% from original.

Nice guiding on this one. This is one of my favorite targets. I want to hit the clusters in Auriga again if I can ever get back out to the observatory.

Yes, I'd like to, too, with a nice smallish Newt that will throw up diffraction spikes and make the stars look like a Christmas card. Also M35, which also has an interesting companion nearby.
