M38 and NGC 1907 (Jan. 2023)

 

This is 19x600" with the Atik 460EXC and LPS-P2 through the SW ED80.  Which is better, the more stretched shot or the less stretched one?  The less stretched one is closer to what the area looks like through a large telescope.  The more stretched one shows stars as deep as 17th magnitude.

M38 and NGC 1907 (Nov. 27, 2013)

 Full resolution image here.

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.
