Description

NGC 4565 (also known as the Needle Galaxy or Caldwell 38) is an edge-on spiral galaxy about 30 to 50 million light-years away in the constellation Coma Berenices.

It lies close to the North Galactic Pole and has a visual magnitude of approximately 10.

It is known as the Needle Galaxy for its narrow profile.

For this picture I selected only the best 257 images (from initial 404 frames of 180s.) on Luminance channel to stack.

It was a long and detailed process to confirm only the best of the best captures, I called them superframes
