This is my second go around with these objects. The first time I shot these was almost two years ago when my processing skill were much more limited, not only that, I only collected 33 minutes of data. This time around I collected 102 minutes of data with the modified camera. Of course I would have liked to get more time but M81 and M82 only are visible for 35 minute windows from my dedicated concrete pier at the Happy Frog so that 102 minutes is over the course of four nights. I hate to take the scope off the pier since it perfectly set but until I get another mount I will have to for some objects.
Although this will not help my overall Messier count since I captured it already, I am much happier
with the results this time around.
