Actually no problem, seeing was very good and on a whim, those are the best, I slewed to epsilon Lyra to split the famous quad. Last subject of last night and didn't bother to take out the dso rig, just shot with reducer and big chip camera in place.

One of my favorite doubles. When I'm introducing people to the telescope, I like to use this target to make sure they understand focusing for their vision. I don't tell them it's a double-double, I let them discover it.
