Description

This mosaic was stitched together from a total of seven overlapping photos using Microsoft's Image Composite Editor (ICE). Each of the panels is a one-minute exposure at f/5.6. No darks, bias or flats were used but I did employ LENR.

The camera was mounted only on a tripod; tracking was provided internally using the camera's Astrotracer feature. This mosaic is accidental because I did not plan it. I just happened to take overlapping shots around that area in the course of evaluating the Astrotracer feature on my first night of using it.

(Note: This mosaic was actually assembled from the out-of-camera jpegs as a test. More detail and less noise should be possible when I redo from the raw files.)
