M49 Galaxy

Messier 49 is an elliptical galaxy belonging to the Virgo Cluster of galaxies. Magnitude 8.4 makes this galaxy the brightest in whole Virgo Cluster. Due to its brightness, it’s possible to observe it just by using binoculars. Distance of M49 from Solar system is 52 million light-years.

The picture is a stack of 40 photos with exposure time 5 minutes each. This means more than 3 hours of exposure time.

Markarian’s Chain

Only few locations on the skies contain so many galaxies as Markarian’s Chain. It belongs to the Virgo galaxy cluster. The brightest galaxies in the center (M84 and M86) were discovered by Charles Messier already in 1781. The smaller one on the left is called NGC 4388, on the right NGC 4402 and at the bottom NGC 4438. These galaxies are located in constellation Virgo between two bright stars Danebola (constellation Leo) and Videmiatrix (Virgo) and they are 50 – 60 million light-years far from the Solar System.

This picture makes me think how big the universe is. Each galaxy contains billions of stars and there is so many of them…

Even though I used my smallest telescope (focal length 600 mm) the whole Markarian’s chain didn’t fit into the field of view. This means I will do mosaic, but probably next year.
