Indeed, wide open. Strange thing, the green and red channels are pin sharp but the blue channel's stars is almost always bit bloated. Focusing was difficult just because of how short the focus throw is.

I think you have to step the f-stop back to 4 or above to get rid of that. I usually go to 5.6 for a lens. I't amazing how big some of the stuff is in the night sky.

since you have image editing marked as ok, I went over your image in PS. I used Gradient Xterminator, and worked on the colors to bring them near what would be visible. Neat widefield....
