Description

I really like this beautiful cosmic flower, but I can't decide if I like the crop better or the widefield.
Now, as the nights are getting longer and cooler, the images are getting better and less noisy.

Yippee!!! My "Tulip in the Swan" has become NASA's "Astronomy Picture of the Day"😃
So cool😎 already my second APOD this year. That has to be celebrated, a clear sky is forecasted tonight😄
