I need to get an artificial star for collimation on the ES David Levy Comet hunter mak-newt. I also know better than to shoot with M81 not only too low, but partially in the Indianapolis light dome. Still, here's one from last night. I was picking up some IFN, but due to my processing skills when stretching it got a bit splotchy so I kind of edited it out. I used the K1 in crop mode.
