NGC4565 is supposed to be very similar to what our Milky Way would look like if you whizzed 31 million ly away and flipped it on its edge. This selection was inspired by Jim Thommes' recent image of this object. It was just a "quick look" at the target, which turned out a lot better than expected. It was a challange to fit this long target on the CCD chip - next time (if there is one, and I hope there is) I will rotate the camera so that the galaxy lies horizontally. Also, my dust collection is building up nicely on the ccd chip, but I didn't capture the required flat field, so you will just have to live with the dust marks (I've tried to hid them as best I can). Time to get out with the mop+bucket methinks.

Captured in k3, stacked in registax with dark. Exported as tiff to photoshop. Curves and minimum filter on bright stars. Slight unsharp mask of dust lanes.
