Yesterday's Splinter Galaxy NGC number was confusing, but this Southern Pinwheel Galaxy was also a mess for me.

Looking at the Stellarium, I see the Southern Pinwheel Galaxy all year round. I didn't care about it before, but when I checked it a few days ago, I found that I could see M83 (NGC5236) now and C70 (NGC300) in autumn. Just like the relationship between Orion and the scorpion, if you can see one, you can't see either.

That's why I added Spring to the title to make a distinction.

Two small galaxies in the east are cute like UFOs.

This is my first LHaRGB photo.
