M90 Galaxy

This is my first image of Messier 90. It is not yet as good as I would like it to be. Which is due to bad weather preventing further imaging. As the moon is already too bright, I will have to postpone further imaging at least to the next new-moon phase.
Nevertheless, this image shows already a beautiful spiral galaxy with its companion.
