Dumbbell Nebula M27

Lights from ... Strasbourg Observatory (France)

Doing astrophotography with a digital camera is one thing, but doing imagery with a monochrome CCD camera is another!

Here is my first image taken with such a configuration, from the educational platform 2T36 of the astronomical observatory of Strasbourg, with Patrick G. , astronomer

The night was quite foggy, and of course, the light pollution very present. That said, we still had a total of 47 minutes of exposure.

The only problem is a bad focus with the OIII filter ...
