Hi all,
after several months without imaging opportunity because of poor weather on the riviera, I was finally able to shoot again my favorite Hydrogen alpha targets!
Because of the heavy light pollution in my area and the high temperatures at night (impossible to cool below -10C), I used long total exposure time to keep good signal.
Here is the result of 6 hours on two nights, on may 26th and 28th.
AP155EDF with Baader Ha 7nm filter.

Comments and criticisms are welcome,
Best regards,
Gilles
