Description

On the 15/16th of March I was imaging Leo's Triplet with a 200mm lens (320mm cropped).
At this time I was not impressed with the results so the data went to a hibernation mode.

Since the current weather went from superb to usual , I searched my image stack again and discovered a strange artifact on the stacked image of Leo's Triplet. It reminded me of my Catalina images. A blink image showed it more clearly. Yes, something was moving here !!

I got curious about the object. One of the astronomy magazines helped me to find a possible candidate. 28 Bellona, a main-belt asteroid of ~125km diameter. Named after a Roman goddess of war by a guy who lived almost 200 years ago.

In realation to the surrounding stars, the moving object has a magnitude of ~10,45

I downloaded the MPC data into Stellarium and compared it with the images. It is most probably Bellona, altough I'm not 100% sure. I'm not a planet guy, I lost my soul to galaxies :-)

The PGC annotated image shows the galaxies around Leo's Triplet. They are plentiful, as usual. The universe is a very generous thing...
