NGC 5033 and others
So when planning this imaging session I wanted to choose something that may not be images alot....taking the road less travelled potentially and boy am i happy i did I have spent multiple weeks under botle 4 skys and an average of 25% moon to capture this gem. In this craft of astrophotography there are always ups and downs and things to learn within and without I have come along way but am still learning every time i sit out under that night sky. let me know your thoughts and i hope you enjoy my attempt at NGC 5033

NGC 5033 is an inclined spiral galaxy located in the constellation Canes Venatici. Distance estimates vary from between 38 and 60 million light years from the Milky Way. The galaxy has a very bright nucleus and a relatively faint disk.
NGC 5033 contains a Seyfert nucleus, a type of active galactic nucleus. Like many other active galactic nuclei, this galaxy's nucleus is thought to contain a supermassive black hole. The bright emission seen in visible light (as well as other wavebands) is partially produced by the hot gas in the environment around this black hole.
Integral field spectroscopic observations of the center of NGC 5033 indicate that the Seyfert nucleus is not located at the kinematic center of the galaxy (the point around which the stars in the galaxies rotate). This has been interpreted as evidence that this galaxy has undergone a merger. The displacement of the Seyfert nucleus from the kinematic center may destabilize the rotation of gas in the center of the galaxy, which could cause gas to fall into the Seyfert nucleus. The gas would be compressed by the enormous gravitational forces in the center of the Seyfert nucleus and become hot, thus making the nucleus appear bright or "active".

Story:

This picture was taken on march 25, 2023 at 21:15 from the slopes of Llaima volcano (Conguillío National Park) in Araucanía region in Chile. We can see the moon and pleiades conjunction, Venus, Urano, Mars and Orion among others.
In the foreground we can see some araucaria trees, commonly called the monkey puzzle tree, monkey tail tree, piñonero, pewen or Chilean pine, which is an evergreen tree native to central and southern Chile and western Argentina, in fact the distribution is bouded between the 37th parallel south and 40th parallel south, mostly in the chilean part of the Andes. Because of the prevalence of similar species in ancient prehistory, it is sometimes called a living fossil; individuals can achieve ages beyond 1,000 years. In this park was filmed the BBC documentary "Walking with Dinosaurs" (1999) for it resemblance to prehistoric landscapes of volcanoes, lagoons and araucaria trees. More recently it was part of the 2022 Netflix documentary "Our Great National Parks" (Episode 2: Chilean Patagonia), presented by former president of the United States Barack Obama.
