This a 15 hour integration of the Lambda Centauri Nebula, or the Running Chicken Nebula ( no clue where is the chicken though), I shot this one from Mar del Plata City in Argentina, a bortle 8 city by the sea over the course of 3 nights. I stacked and preprocess with AstroPixelProcessor, then Pixinsight and finally Photoshop.

Taken with an Esprit 100ED and an ASI2600mm pro with Antlia 2.8 filters.

It has been so long since I had a clear night that I thought I would try a target I have not looked at before. The result may not look as spectacular as some I have posted, but the detail in there is staggering.

 

In the constellation of Coma Berenices there is a cluster of thousands of galaxies. The centre is about 320 million light-years away and is flying away from us at the rate of about more than 15 million mph (24 million kph)!

 

The Coma Berenices galaxy cluster is one of the most populated galaxy clusters known. Scientists estimate that it contains as many as 10,000 or more members. Indeed, there are more individual galaxies in this cluster than there are stars visible to the unaided human eye on a clear, dark night.

I have posted another image which is not annotated so you can see the objects more clearly.

 

Most galaxies in the central part of the cluster are elliptical. Elliptical galaxies are the result of galaxy mergers. The two brightest members are NGC 4889 and NGC 4874, both of which are giant ellipticals. They are at least two to three times larger than our own Milky Way galaxy. Farther out from the centre are several spiral galaxies.

 

Above the centre of this image NGC 4921 is a large barred spiral galaxy. That galaxy is three times as large as the Milky Way.

M 106 (conosciuta anche come NGC 4258) è una galassia a spirale visibile nella costellazione dei Cani da Caccia; sembra che il suo interno ospiti un buco nero supermassiccio.

La distanza della galassia è stimata sui 21-25 milioni di anni luce e la sua massa totale è pari a circa 190 miliardi di masse solari; si allontana da noi alla velocità di 537 km/s.
