    Description

    This is a 16-frame mosaic. This time, I decided to go relative narrow-field with high resolution. The consequence is it is not very deep.

    The original mosaic has 683 Mega pixel, and it's not practical to upload such a large image. The version uploaded here is a 25% reduction.

    Astrobin seems to have some problem displaying images at this moment. If you have trouble seeing this image, you can go to my Flickr page:
