M101 Windmill galaxy


Recently I made images of M101. Color was not perfect yet, but then I got a message from Irving Pieters who offered to share his data. We combined our data and stacked them together. He also had good colordata, with as a result the attached image. Some of the weak structures around M101 already start to show up. I hope in May, when I go for holiday to the Eifel, to grab some more very deep data to make these faint structures even better visible.
