M51 was the last picture from this season that I managed to get light to all filters. I am certain that I come back to this target later. Ha-data was very thin, only 10 frames. And also luminance and color could use some more. But very happy for the picture as it is now. And perhaps next fall or one after that it is even better. Now it's time to do some maintenance for the next 4 months with no dark nights.
