We had to install a stronger motor to the focuser (the focuser tube weights 30kg) and
after the repair we used the clear night to take some more pictures.
The extreme tracking performance of this telescope allowed to track the
telescope blind without any tracking corrections for 2m integration times. After a better
polar alignment maybe 10m will be possible.
Professional astronomers have measured, that the center of M64 is rotating in the
opposite direction than the outer regions! Stranger still - there is a middle region where
the stars rotate in the opposite direction from the surrounding dust and gas. They think,
that this could be the the result of a collision between a small galaxy and a large
galaxy - where the resultant mix has not yet settled down.
