Description

I could not resist to have a try at this very nice group of 4 galaxies about 100 million light-years distant toward the constellation Leo.

For the Light , I selected around half of the best Fwhm subs and combined them with all the subs to get sharper details and smaller stars
4 nights were necessary to get the subs: 09/10, 26, 27 and 30 of mars
