NGC 5907 (3-3-2018)-2j.jpg

 

This fascinating edge-on galaxy lies off the handle of the Big Dipper in the constellation of Draco (The Dragon). Called the Splinter Galaxy, this galaxy shows a notable dust lane, but no significant central bulge. Very deep images reveal an expansive loop of faint stars that are a remnant of an encounter with a smaller galaxy in the distant past. If you look carefully just to the upper right of the Splinter you’ll find a tiny smudge; the distant galaxy PGC 4541551 glowing faintly at Mv 16.8.

That appears to be NGC 5907 also in Draco. Regardless a very nice capture.

Doh! You're right. This is the second time that I have done this, which is why I have no record of imaging NGC 5866, But I have previously imaged 5907. :)

 

Thanks!

Very well done!  I can see some fine detail of the dust tendrils around the edge.  I enjoyed imaging this last year.
