I finally found some time to you process this interesting group of galaxies : the largest NGC3718 with warped arms and NGC3729, both interacting gravitationnaly at around 52 millions light-years, but also Hickson 56 , the group at the bottom of NGC3718 at over 400 millions light-years.

Red 46 subs@180s -20°C gain zero
Blue 25 subs@180s -20°C gain zero
Green 30 subs@180s -20°C gain zero
Light 142subs@180s -20°C, gain zero

3 nights were necessary to get the subs: 07/08, 08/09 , and 11/12 of March
