OBJECT DESCRIPTION AND IMAGE SESSION

A faint and small planetary nebula in the constellation of Sagittarius located almost at the middle distance of Gamma and Eta Sagittarii. this object can be seen with a telescope at 87x with adverted vision. Larger apertures (8 to 10 inches) could detect its round shape and with the help of narrowband filters the thin arc at the limb can be visualized.

Moon was almost at full phase however I was impressed by the background stars capture by the C8 considering also that the transparency was not very good
