IMAGE DETAILS

NGC 2903 IS A VERY NICE SPIRAL GALAXY WHICH WAS FIRST DISCOVERED BACK IN 1784 BY WILLIAM HERSCHEL. IT IS AT A DISTANCE OF ABOUT 20.5 MILLION LIGHT YEARS FROM US AT A MAGNITUDE OF 9.09.

AT THE BOTTOM OF THIS IMAGE THERE IS A PASSING OBJECT WHICH COULD BE MINOR PLANET HEDDA (MAG 12.7) (THANKS DUNCAN). IT IS MOVING TO THE RIGHT AND THE COLOURS CORRESPOND TO WHAT FILTER I WAS USING AT THE TIME OF ITS PLACEMENT.
