strong wind and bad seeing
Philipp Keller and Christian Fuchs
This is a very nice object located in Perseus. IR-exposures show that in the center
of the nebula new stars are born.
We had tracking errors in this exposure due to the strong wind (about 5Bft) that caused
vibrations inside the tube structure. The telescope is standing free and the wind puts a
strong load on the newtonian light shroud. Also the seeing was a mess as it was all the 3
days during this clear period.
