A Rosette by any other name . . .

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.
