The galaxies NGC5566, NGC5569, and NGC5560 form a triplet known as Arp286. This triplet is an extension of the Virgo cluster. The redshift of the 2 smaller galaxies are almost identical , thus very probably at the same distance of 78 millions light years.

Red 20subs@180s -20°C gain zero
Blue 20subs@180s -20°C gain zero
Green 20subs@180s -20°C gain zero
Light subs@180s -20°C, gain zero

4 nights were necessary to get the subs: 25/26 , 26/27, 31/01, and 02 of June

Don't hesitate too look at the full field :-)
