Caldwell 49 is one of the objects in my catalog of images that I’ve wanted to capture for a good long while. It is absolutely massive and generally lends itself well to grab and go wide field imaging. Polar alignment is less critical than at high f/ratio and field rotation is thus less obvious. I still strive for zero rotation and translation and in this case I got that. I only got to capture 35 minutes of data before it disappeared behind a tree so there is still much to be desired. Another attempt at this will be made next year.
