A difficult nebula!

This was one of my favorite objectives and finally I got it! 
The Crab Nebula, located in the constellation of Taurus, is a supernova remnant, the result of a cataclysmic supernova explosion in the year 1054. This explosive death of a star was so bright that it could be seen in the daytime sky for 23 days, and was documented by astronomers in China.
It was not an easy night, so wet! For the first time I used a hairdryer against the dew on the corrector plate and it worked pretty well. I made two sessions of 30 1 min shots each, using the hairdryer before and in between the two sessions.
