The Andromeda Galaxy - M31 (and companion galaxy M32)
I captured multiple frames at ISO 6400 with a Nikon D5000.
These were stacked in Deep Sky Stacker.
I used various processing to highlight dustlanes in some images, galactic core in others.
The image with vertical bars is from a trial run in 'Nebulosity', thanks to a tip from Robin.
Finally I puzzled over two bizarre objects North East of the Galaxy in the final image.
I confirmed these are not processing artifacts by finding them on published images.
Historical images From LAROUSE 'Encyclopedia of Astronomy'
Revised Edition 1966
I inherited an Astronomy book published in 1966
and it contains historical images from Mt Wilson, Yerkes and other
famous observatories. The images below were taken in 1920 and 1901 respectively.
Its interesting to compare the dust lane detail from over 100 years ago!
