When M 77 was discovered by Mechain, in 1780, he described it as a nebula. When Messier incorporated it to his catalog, he assigned it the category of a star cluster (by the way, Herschel also did the same mistake…). It was Lord Rosse who identified it as a “spiral nebula” mid XIX Century. M 77 is larger than the Milky Way and it is an active Seyfert galaxy. Being the closest such galaxy to us, it is a thoroughly studied galaxy. This image was taken with the Schulman Telescope (32″) from Sky Center, Mount Lemmon, AZ. This one is my version.
