The evening of 19 May 2025 was cool, partly cloudy to clear, with variable thin clouds after midnight. Draco is full of double stars. My favorites are Nu Draconis (STFA 35), 17 Dra (STF 2078) and Mu Dra (STF 2130) The latter two I was able to observe at 104x with 81mm refractor. 

 

The following are 29 targets of interest in the celestial dragon.
