We have collected the main nebulae located in the southern sky of the Milky Way in summer, but there is one that was left behind, the nebula called Rim Nebula (NGC6188) at the southernmost tip. The name Fighting Dragons Of Ara is probably more famous now than the name Rim nebula. At first I aimed at Rim, but there were "Thai King's Tree", "12-3 electric wires", and "Palm Leaf" between the telescope and this nebula, which was impossible at wide angle. So I took a picture of this dragon's egg just west of Rim.
In fact, this nebula, a blue nebula spreads thinly around this red egg. I wanted to fit that much, but the total exposure wasn't enough. I want to be exposed for another one and a half hours. I will try again next season until the blue part.
It's difficult to get blue,,,,
