Sombrero Galaxy is an spiral galaxy in the constellation Virgo located 31 million light-years from Earth. Smaller than the Milky Way, M104 has a diameter of approximately 50,000 light-years and has a bright nucleus. A prominent dark dust lane and a central bulge give this galaxy the appearance of a sombrero.
I am really liking the Synthetic Flat-Layer gradient removal method described by Trevor Jones from AstroBackyard to cleanup the gradients. Since I do not use flats yet, my stacked image is loaded with vignetting and gradients. I used to spend an enormous amount of time trying to make a decent image, however, this new method described by Trevor has cut my time in half and produces better results. Of course using flats will make a world of difference as well but I have not been able to do it properly yet. I need to see a video of somebody actually doing it in the field.
This represents number 76 on my catalog of Messier objects, only 34 remain.
