Another object I've imaged before. I'm repeating these so that I have a record of improvements I've made in the different objects as I learn more about capturing and processing these images. The Rosette Nebula, SH2-275 or Caldwell 49 is a hydrogen rich region in the constellation Monoceros. Monoceros is located one constellation east of Orion.
This is a big object, over 1 degree in diameter. It almost will not fit in the field of view of a 700mm focal length telescope imaged by an APS-C crop sensor DSLR.
