M51 "Whirlpool" Galaxy
I shot M51 between cloud bands tonight, having about three hours to shoot, but needing about an hour to set up and running out of camera battery power about 40 minutes into shooting the object :-(. Will try and get some more data later in the week and add to it. It's still not as sharp and bright as I am aiming for. I think I need to take longer exposures using autoguiding, but can't really do that until I have a good outdoor power supply for my laptop. In any case, light pollution at the local observing spot really keeps me limited to two minute exposures. Maybe two hour's worth of exposures might do the trick.
