The Dolphin Nebula (いるか星雲) SH2-308  2 Panels Mosaic

I shoot this OBJECT every year because I love dolphins, but this year I had to use Mosaic because I was shooting with RC10.
To be honest, I still don't have enough Signals to reach my goal this time, so if there are no clouds, I'd like to collect more during this bright moon.

22nd/Feb =>イルカが好きという理由で毎年このOBJECT撮影してるが、今年はRC10での撮影のため
Mosaicで対応せざるを得なかった。
正直今回の目標点にはSignalがまだまだ足りないので、雲さえなければこの明月の時期にもっと集めたいな。
23rd/Feb==>そこそこSignalは集まったが、星がイマイチだな〜。RGB足したいな。
