Hi Everyone, Last year I imaged this beautiful object with a 400 mm of focal length apo refractor, this year I use a 250 Newton with 1086 mm of focal length.

I hope you enjoy it, in this time, I dedicate this image to the love of my life, Cecilia Vazquez, who is celebrating her 37th birthday today!
