This is a spiral galaxy in the northern constellation of Canes Venatici and is about 25-29 million light-years away. It contains about 400 billion stars, as compared to 250 billion stars in our own Milky Way galaxy. The 'Sunflower' sports a bright yellow core, hence its name. This deep space object is high in the ENE around 1 am in early March. This is a two-hour exposure plus an additional 30 minutes from March 1 added to the luminance channel. The sky was crystal clear Tuesday night (March 5).
