    This is maybe an usual image but I've tried to make it unusual in some way. I've noticed, using the Microsoft virtual telescope, a certain amount of Ha presence in that area. The image itself it's nothing fancy, just 10min RGB frames of the double cluster in Perseus, acquired two years ago during an astrocamp in Italy. So I've managed to add about 4 hours of Ha data acquired from the city and in bin 2x2 using 40 minutes subframes. This is the result, a well known subject with a very unknown extent of Ha nebulosity.

    Hope You like it.
