GALAXIES

The following images are "thumbnails" of a few large spiral galaxies that can be observed from my Arizona residence.

For brevity only a 1-line description for each image is given on this web page.  For most of the objects a link is provided that will present a larger image, usually cropped, with a description of equipment, exposures and processing.  The thumbnails will all be at the same scale ["arc/pixel], which should afford a quick way of comparing sizes of the different galaxies. Some cropping is usually made for all images on this and linked pages, and most images will have been processed to show faint spiral arm features as well as contrast within the bright central region. I use MaxIm DL's digital development for most of these processing enhancements.
