Matthias Juchert, 8", fst 6m7:
A wonderful object full of details! At 126x very large, very long. The galaxy is divided into 3 parts by 2 dark lanes. All in all the galaxy appears very mottled. The southern part between the two dark lanes is characterized by obvious bright knots. Three more knots are visible in the western part of the nebula. The eastern part is not structured that much.
