Description

I decided to double the exposure time of RGB even they are shot with bin2. That pays off well, SNR has been improved quite a lot. F7 of TEC140 is bit of slow and can use more time.

M100 is one of the brightest and largest galaxies in the Virgo Cluster and is approximately 55 million light-years from our galaxy, its diameter being 107,000 light years, and being about 60% as large. It was initially discovered by Pierre Méchain in 1781 and 29 days later seen again  by Charles Messier. He then added it  in his catalogue .
